Which opening in a vertebra allows passage of the spinal cord?
Transverse foramen
Spinous process
Body
Vertebral foramen
The vertebral foramen is the central opening formed by the vertebral body anteriorly and the vertebral arch posteriorly, creating the vertebral canal that houses the spinal cord. The body is primarily for weight bearing, while the spinous and transverse processes serve as muscle attachment sites. Transverse foramina are only present in cervical vertebrae and transmit the vertebral artery. Learn more
Which bony projection is located posteriorly on a vertebra and serves as a site for muscle attachment?
Lamina
Transverse process
Spinous process
Pedicle
The spinous process projects posteriorly from the junction of the two laminae and serves as a crucial attachment point for muscles and ligaments of the back. The transverse processes extend laterally for muscle and ligament attachment as well. Pedicles connect the vertebral body to the arch, while laminae form part of the arch itself. Learn more
Which structure connects the vertebral body to the transverse process?
Lamina
Pars interarticularis
Pedicle
Articular process
The pedicle is a short, stout process projecting posteriorly from the vertebral body to join the transverse process, forming the sides of the vertebral arch. Laminae join the pedicles to complete the arch posteriorly. The pars interarticularis is the region between superior and inferior articular facets. Articular processes are projections that articulate with adjacent vertebrae. Learn more
Which vertebral structure forms the posterior wall of the vertebral foramen?
Lamina
Pedicle
Vertebral body
Spinous process
The laminae are paired plates of bone extending from each pedicle to the midline, forming the posterior portion of the vertebral arch and thus the posterior wall of the vertebral foramen. The spinous process projects at the junction of both laminae. Pedicles form the lateral walls of the foramen, and the vertebral body forms the anterior wall. Learn more
Which process on a vertebra contributes to the zygapophyseal (facet) joint?
Spinous process
Pedicle
Articular process
Transverse process
Articular processes (superior and inferior) extend from the junction of the pedicle and lamina and articulate with adjacent vertebrae, forming the zygapophyseal (facet) joints that guide and limit spinal movements. The spinous and transverse processes serve muscle attachment roles but do not form these joints. Pedicles connect the body to the arch. Learn more
Which feature is unique to cervical vertebrae?
Sacral foramina
Costal facets
Mammillary processes
Transverse foramina
Cervical vertebrae (C1 - C7) uniquely contain transverse foramina in each transverse process, through which the vertebral arteries ascend toward the brain. Costal facets are a feature of thoracic vertebrae, mammillary processes are found in lumbar vertebrae, and sacral foramina are in the sacrum. Learn more
The atlas (C1) differs from other cervical vertebrae by lacking which structure?
Transverse process
Facet
Vertebral body
Lamina
The atlas (C1) lacks a vertebral body and spinous process; instead it consists of anterior and posterior arches. It supports the skull at the occipital condyles and allows the nodding motion of the head. All other cervical vertebrae have a distinct body. Learn more
Which typical cervical vertebra often has a bifid spinous process?
C5
C2
C7
C1
Typical cervical vertebrae (C3 - C6) often feature a bifid (split) spinous process, which serves as an attachment for ligaments and muscles in the neck. C5 is a representative typical cervical vertebra. C1 and C2 are atypical, while C7 usually has a long, non-bifid spinous process. Learn more
Which vertebra articulates directly with the occipital condyles of the skull?
C7
C3
Axis (C2)
Atlas (C1)
The atlas (C1) vertebra has superior articular facets that articulate with the occipital condyles of the skull, forming the atlantooccipital joint which permits the nodding motion of the head. The axis (C2) articulates with the atlas, not directly with the skull. Learn more
How many vertebrae are fused to form the adult sacrum?
Five
Four
Seven
Six
The adult sacrum is formed by the fusion of five sacral vertebrae (S1 - S5), creating a triangular-shaped bone that connects the spine to the pelvis. Fusion begins during adolescence and is usually complete by the third decade of life. Learn more
Through which opening does the vertebral artery ascend in the cervical spine?
Intervertebral foramen
Spinous foramen
Transverse foramen
Vertebral foramen
The vertebral artery enters the transverse foramen of C6 (and sometimes C7) and ascends through successive transverse foramina of cervical vertebrae to reach the skull. Intervertebral foramina transmit spinal nerves, not arteries. Learn more
At which vertebral level does the spine of the scapula lie?
T5
T1
T3
T7
The spine of the scapula lies at the level of the T3 vertebra posteriorly, serving as a useful surface landmark during physical examination. T7 corresponds to the inferior angle of the scapula. Learn more
Which joint permits rotation of the head around the dens?
Atlantoaxial joint
Atlantooccipital joint
Intervertebral disc joint
Zygapophyseal joint
The atlantoaxial joint, formed between the atlas (C1) and axis (C2), allows for approximately 50% of cervical rotation through articulation of the dens (odontoid process) with the anterior arch of the atlas. The atlantooccipital joint allows nodding. Learn more
Which spinal curvature is present at birth?
Cervical
Lumbar
Thoracic
Pelvic
Primary spinal curvatures - thoracic and sacral - are concave anteriorly and are present at birth, reflecting the original fetal C-shape. Secondary curvatures (cervical and lumbar) develop as the infant lifts its head and begins to sit or stand. Learn more
The lumbosacral angle is normally around which value?
15°
60°
30°
45°
The lumbosacral angle - formed between the long axis of the lumbar spine and the sacrum - averages about 30° in healthy adults, influencing posture and load transmission. Deviations can contribute to back pain. Learn more
The facet joints of the lumbar spine are oriented primarily in which plane?
Transverse
Horizontal
Sagittal
Coronal
Lumbar zygapophyseal (facet) joints are oriented in the sagittal plane, which allows flexion and extension while limiting rotation. Thoracic facets are more coronal, and cervical facets are more horizontal. Learn more
Which ligament runs along the anterior surfaces of vertebral bodies and intervertebral discs?
Posterior longitudinal ligament
Anterior longitudinal ligament
Ligamentum flavum
Supraspinous ligament
The anterior longitudinal ligament runs along the anterior aspect of vertebral bodies and intervertebral discs from the occiput to the sacrum, preventing hyperextension of the spine. The posterior longitudinal ligament lies within the vertebral canal on the posterior aspect of the bodies. Learn more
The intervertebral foramen is bounded superiorly and inferiorly by which structures?
Pedicles
Spinous processes
Laminae
Transverse processes
Each intervertebral foramen is formed by the superior vertebral notch of the vertebra below and the inferior vertebral notch of the vertebra above, both located on the pedicles. This foramen transmits spinal nerve roots and vessels. Learn more
Which of the following ribs is classified as a false rib?
Rib 1
Rib 2
Rib 7
Rib 8
False ribs (ribs 8 - 12) do not attach directly to the sternum; ribs 8 - 10 connect via costal cartilage of the rib above. Ribs 1 - 7 are true ribs with direct sternal articulation. Ribs 11 and 12 are floating ribs. Learn more
The sternal angle marks the junction between which two parts of the sternum?
Body and xiphoid
Manubrium and clavicle
Manubrium and body
Body and costal cartilage
The sternal angle (angle of Louis) is the palpable ridge formed at the junction of the manubrium and the body of the sternum. It is a key surface landmark corresponding to the second rib and the T4 - T5 vertebral level. Learn more
Which rib articulates with the body of the sternum directly and a single vertebral level?
Rib 1
Rib 2
Rib 7
Rib 10
Rib 1 articulates only with the manubrium of the sternum at the first sternocostal joint and with the body of T1 vertebra. Ribs 2 - 7 articulate directly with the sternum but span two vertebral levels (the vertebra above and the corresponding vertebra). Learn more
In lumbar vertebrae, the mammillary processes arise from which structure?
Transverse process
Pedicle
Superior articular process
Lamina
Mammillary processes are paired projections on the posterior aspect of superior articular processes of lumbar vertebrae and serve as attachment points for the multifidus muscle. They are unique to lumbar vertebrae. Learn more
The anulus fibrosus of an intervertebral disc is rich in which collagen type?
Type IV
Type II
Type I
Type III
The anulus fibrosus consists of concentric lamellae of fibrocartilage that are rich in type I collagen in peripheral layers, providing tensile strength to resist torsional and shear forces. Type II collagen predominates in the nucleus pulposus. Learn more
Luschka's joints are found between which structures in the cervical spine?
Spinous processes
Articular processes
Transverse processes
Uncinate processes
Luschka's joints, or uncovertebral joints, are formed by the uncinate processes on the superolateral edges of the vertebral bodies of C3 - C7 articulating with the vertebral body above. They help guide cervical motion and can develop osteophytes. Learn more
The dens (odontoid process) of the axis projects into which feature of the atlas?
Posterior arch
Superior articular facet
Transverse process
Anterior arch
The dens of C2 (axis) projects superiorly into the anterior arch of C1 (atlas), held in place by the transverse ligament of the atlas, allowing pivot rotation. The superior articular facets of the atlas articulate with the occipital condyles, not the dens. Learn more
Thoracic vertebrae have costal facets located on which parts of the vertebra?
Spinous process and lamina
Body and transverse process
Pedicle and lamina
Body only
Typical thoracic vertebrae feature costal demifacets on the lateral aspects of the vertebral bodies and a full facet on the transverse processes, which articulate with the heads and tubercles of ribs respectively. No costal facets are on the spinous or pedicle regions. Learn more
The ligamentum flavum connects which structures?
Adjacent laminae
Vertebral bodies
Transverse processes
Spinous processes
The ligamentum flavum is a series of elastic ligaments connecting the lamina of one vertebra to the lamina of the vertebra above, helping to preserve normal curvature and assist in returning to extension. It lies within the vertebral canal posterior to the spinal cord. Learn more
Which vein collects blood from the vertebral bodies and drains into the internal vertebral venous plexus?
Basivertebral veins
Great anterior radicular vein
Anterior spinal vein
Accessory hemiazygos vein
Basivertebral veins run within the vertebral bodies and drain into the internal vertebral venous plexus, providing a valveless pathway for blood flow and potential metastasis. They exit through basivertebral foramina on the posterior surface. Learn more
The neurocentral synchondroses of vertebrae typically fuse at approximately what age?
At birth
20 years
3 - 6 years
Puberty
Neurocentral synchondroses are cartilaginous growth plates between the vertebral body and arch portions in children, fusing by around 3 - 6 years of age to form a continuous bone. Failure to fuse can predispose to scoliosis. Learn more
Which spinal curvature develops when an infant begins to lift the head?
Pelvic curvature
Thoracic curvature
Cervical curvature
Sacral curvature
The secondary cervical curvature develops as an infant starts to lift its head when prone, creating a concave anterior curvature. The lumbar secondary curvature appears when the child begins to stand and walk. Primary curvatures (thoracic, sacral) are present at birth. Learn more
In adults, the intervertebral discs account for approximately what percentage of the spine's total length?
5 - 10%
40 - 45%
20 - 25%
30 - 35%
Intervertebral discs (23 discs) account for about 20 - 25% of the total spinal column length in adults, providing flexibility and shock absorption. Loss of disc height can contribute to reduced stature and back pain. Learn more
The nucleus pulposus of the intervertebral disc is embryologically derived from which structure?
Dermatome
Notochord
Neural tube
Sclerotome
The nucleus pulposus is derived from remnants of the embryonic notochord, while the anulus fibrosus and vertebral bodies arise from sclerotome. This embryologic origin explains the gelatinous nature of the nucleus and its resistance to compressive forces. Learn more
Basivertebral veins drain the vertebral bodies into which venous network?
Internal vertebral venous plexus
Hemiazygos vein
Azygos vein
External vertebral venous plexus
Basivertebral veins collect blood within the vertebral bodies and drain into the internal vertebral venous plexus located in the epidural space. This valveless plexus communicates with pelvic and cranial veins, facilitating metastatic spread. Learn more

Cheat Sheet

  1. Cervical Vertebrae Identification -

    Before starting a vertebrae labeling quiz, recall that C3 - C6 have bifid spinous processes and transverse foramina for vertebral arteries (Gray's Anatomy, 41st ed.). C1 (atlas) lacks a body and spinous process, while C2 (axis) features the odontoid process (dens) essential for head rotation.

  2. Thoracic Vertebrae Landmarks -

    Thoracic vertebrae T1 - T12 each articulate with ribs via costal facets on the body and transverse processes (American Journal of Anatomy, 2020). Use the mnemonic "Twelve thoracic, time for meals" to remember that T1 - T12 correspond to ribs 1 - 12 for your thoracic vertebrae quiz.

  3. Lumbar Vertebrae Characteristics -

    L1 - L5 have large, kidney-shaped bodies and short, sturdy spinous processes adapted for weight-bearing (Journal of Orthopaedic Research, 2019). Recognize their broad vertebral foramen and accessory processes to distinguish lumbar vertebrae on your vertebral column labeling quiz.

  4. Thoracic Cage Components -

    The sternum consists of the manubrium, body, and xiphoid process, while ribs are classified as true (1 - 7), false (8 - 10), and floating (11 - 12) (Netter's Atlas of Human Anatomy). Remember "True Fabulous Floaters" to ace the label thoracic cage section.

  5. Vertebral Arch Anatomy -

    The vertebral arch is formed by pedicles and laminae that protect the spinal cord, with superior and inferior articular processes facilitating intervertebral articulation (Spine Journal, 2018). Use the handy "PLIP" mnemonic - Pedicles, Lamin a, IAP (Inferior Articular Process), and PAP (Superior Articular Process) - for quick recall during the thoracic vertebrae quiz.
