There are 7 cervical vertebrae which are the bones that make up the neck region. This is a fundamental fact about human vertebral anatomy.
Which vertebra directly supports the skull, allowing the nodding motion?
Coccyx
Sacrum
Axis
Atlas
The atlas (C1) supports the skull and allows the nodding motion. It is uniquely shaped to articulate directly with the occipital condyles.
Which feature is unique to the cervical vertebrae when compared to other spinal regions?
Fusion of vertebrae
Costal facets
Transverse foramina
Large vertebral bodies
The transverse foramina, which house the vertebral arteries, are distinctive to the cervical vertebrae. This feature helps differentiate them from thoracic and lumbar vertebrae.
What is the term for the inward curvature of the cervical spine?
Kypholordosis
Scoliosis
Kyphosis
Lordosis
Cervical lordosis refers to the natural inward curve of the cervical spine. This curvature is important for proper weight distribution and balance.
What does the term 'vertebrae' refer to in human anatomy?
Bones of the spine
Bones of the arm
Bones of the skull
Bones of the rib cage
Vertebrae are the individual bones that form the vertebral column, or spine. They provide structural support and protect the spinal cord.
What is the primary function of the intervertebral discs in the cervical spine?
Provide cushioning and shock absorption
Facilitate nerve conduction
Increase vertebral size
Support muscle attachment
Intervertebral discs act as shock absorbers, cushioning the vertebrae during movement. They help distribute loads evenly across the spine.
Which cervical vertebra is characterized by its ring-like shape and lack of a vertebral body?
C4
C7
Axis
Atlas
The atlas (C1) is uniquely shaped as a ring-like structure that supports the skull. It lacks a vertebral body, distinguishing it from other vertebrae.
On which cervical vertebra is the odontoid process (dens) found?
C7
Atlas (C1)
C3
Axis (C2)
The odontoid process, or dens, is a key feature of the axis (C2) vertebra. It provides a pivot point for the rotation of the atlas and the head.
What structure passes through the transverse foramina of the cervical vertebrae?
Spinal cord
Vertebral artery
Jugular vein
Nerve roots
The vertebral artery travels through the transverse foramina, supplying blood to the brain. This pathway is a unique feature of cervical vertebrae.
Which cervical vertebra is known for having a particularly prominent spinous process?
C3
C6
C4
C7
C7 is recognized as the vertebra prominens due to its elongated and prominent spinous process. This makes it a key landmark for identifying the cervical spine.
What is the main function of the facet joints in the cervical spine?
Support weight-bearing only
Transmit blood vessels
Serve as attachment points for ligaments
Allow movement while providing stability
Facet joints in the cervical spine allow controlled movement between vertebrae while ensuring stability. They are crucial for the spine's range of motion.
Cervical lordosis represents which of the following?
A lateral bend in the spine
Normal inward curvature of the neck
A reversed curvature of the spine
A straightened spinal alignment
Cervical lordosis refers to the natural inward (anterior) curvature of the cervical spine. This curvature is essential for proper load distribution and posture.
Which factor is a common cause of cervical spine injury in young athletes?
High-impact sports
Moderate exercise
Balanced stretching
Desk work
High-impact sports can lead to collisions and falls, increasing the risk of cervical spine injuries in young athletes. These injuries may result in strains or more severe damage.
What anatomical feature distinguishes the C7 vertebra from other cervical vertebrae?
A more prominent spinous process
Its smaller size
An extra vertebral body
Absence of transverse foramina
C7 has a distinctly prominent spinous process that sets it apart from other cervical vertebrae. This feature makes it a useful landmark in physical examinations.
Between which two cervical vertebrae is disc herniation most commonly observed?
C3-C4
C5-C6
C6-C7
C4-C5
The C5-C6 segment is highly mobile and often subject to degeneration and herniation. This region is thus a common site for cervical disc issues.
Which of the following best describes the significance of the transverse foramina in cervical vertebrae?
They serve as attachment sites for muscles
They reduce weight by creating openings
They provide cushioning between vertebrae
They allow passage of the vertebral arteries
The transverse foramina are openings specifically designed to allow the vertebral arteries to ascend into the brain. This unique anatomical feature is critical for cerebral blood circulation.
Which structural feature of the axis (C2) facilitates the head's pivot rotation?
Transverse process
Shoulder facet
Bifid spinous process
Odontoid process (dens)
The odontoid process, or dens, of the axis serves as a pivot for rotation, allowing the atlas and head to turn. This unique structure is essential for head rotation.
A reduction in the normal cervical lordosis is most often indicative of which condition?
Vertebral fusion
Muscle spasm or strain
Improved posture
Increased flexibility
A decreased cervical lordosis typically signals muscle spasm or strain as the muscles contract to protect an injured area. It is considered an abnormal finding compared to the normal curvature.
Which of the following best highlights the differences between cervical and thoracic vertebrae?
Cervical vertebrae are fused whereas thoracic vertebrae are separate
Cervical vertebrae have costal facets while thoracic vertebrae do not
Cervical vertebrae have transverse foramina while thoracic vertebrae have rib facets
Cervical vertebrae are larger and support more weight than thoracic vertebrae
The major distinguishing feature is that cervical vertebrae have transverse foramina for the vertebral arteries, while thoracic vertebrae have rib facets for rib attachment. This difference reflects the distinct functions and structures of these spinal regions.
Which imaging technique is most appropriate for assessing cervical spine alignment and curvature?
X-ray
CT scan
MRI scan
Ultrasound
X-rays are commonly used to evaluate the alignment, curvature, and structural integrity of the cervical spine. They are accessible and effective for assessing bony structures.

Cervical Vertebrae & Column Cheat Sheet

  1. The seven cervical vertebrae - The cervical spine has seven vertebrae (C1 - C7) that support the skull and enable head movement. The atlas and axis have unique shapes for nodding and rotation. Together they balance stability and flexibility in the neck. TeachMeAnatomy: Cervical Spine Overview
  2. Typical cervical vertebrae (C3 - C6) - Typical cervical vertebrae (C3 - C6) have small bodies and bifid spinous processes for muscle attachment. Their transverse foramina allow vertebral artery passage to the brain. These features enhance neck flexibility and blood flow safety. Easy Anatomy App: Typical Cervical Vertebrae
  3. Structure of the atlas (C1) - The atlas (C1) lacks a vertebral body and a true spinous process. It consists of anterior and posterior arches connecting lateral masses. This ring-like design supports the skull and enables the "yes" nodding motion. TeachMeAnatomy: C1 Atlas Structure
  4. Role of the axis (C2) - The axis (C2) features the odontoid process or dens, a tooth-like projection. The dens acts as a pivot allowing the atlas to rotate around it. This setup makes the "no" head movement possible while protecting the spinal cord. TeachMeAnatomy: C2 Axis Anatomy
  5. Vertebra prominens (C7) - The seventh cervical vertebra (C7) is called the vertebra prominens for its long spinous process. Its non-bifid spine is easy to feel at the base of the neck. Clinicians use it as a landmark to count and identify other vertebrae. Elsevier: Cervical Vertebrae Overview
  6. Intervertebral discs - Intervertebral discs sit between cervical vertebrae, acting as shock absorbers. They consist of a gel-like nucleus and a tough outer ring. These discs cushion impacts and help maintain neck mobility. Cleveland Clinic: Cervical Spine Discs
  7. Facet joints - Facet joints are small synovial joints at the back of each vertebra. They have smooth cartilage surfaces for pain-free gliding movements. Facet joints work with discs to give the neck a wide range of motion. Verywell Health: Cervical Vertebrae & Facet Joints
  8. Cervical ligaments - Ligaments like the anterior and posterior longitudinal and nuchal ligaments stabilize the cervical spine. The ligamentum flavum connects adjacent laminae, adding spring-like support. These ligaments prevent excessive movement and protect the spinal cord. TeachMeAnatomy: Cervical Ligaments
  9. Cervical nerves - The cervical spine houses the spinal cord and eight pairs of nerves (C1 - C8). These nerves exit through foramina to deliver sensory and motor signals. Proper nerve function is crucial for head, neck, shoulder, and arm movement. NCBI: Cervical Spine and Nerves
  10. Posture & exercises - Good posture and neck-strengthening exercises reduce the risk of cervical disorders. Ergonomic work setups and regular movement help prevent pain and degeneration. Strong neck muscles support spinal alignment and long-term health. Cleveland Clinic: Cervical Spine Health Tips
