What is the primary function of the intervertebral disc?
Facilitate blood flow to the spinal cord
Shock absorption and load distribution between vertebrae
Conduction of nerve impulses along the spine
Production of synovial fluid for facet joints
Intervertebral discs sit between adjacent vertebral bodies and function primarily to absorb shock and distribute loads during movement. Their elastic, gel-like center and fibrous outer ring allow the spine to handle compressive forces, protecting vertebrae and spinal nerves. Discs do not conduct nerve impulses or produce synovial fluid. Learn more.
Which component of the disc is gelatinous and centrally located?
Annulus fibrosus
Nucleus pulposus
Vertebral endplate
Facet cartilage
The nucleus pulposus is the central, gelatinous component of the intervertebral disc rich in proteoglycans and water, which grants it hydrostatic pressure properties for shock absorption. It is surrounded by the tougher, fibrous annulus fibrosus. Learn more.
What type of joint characterizes the intervertebral disc between vertebral bodies?
Synovial joint
Symphysis
Gomphosis
Synchondrosis
Intervertebral discs form symphyses, a type of cartilaginous joint where fibrocartilage (the disc) unites two bones. This allows limited motion and provides strength for load bearing. Synchondroses involve hyaline cartilage and gomphoses are peg-in-socket joints. Learn more.
Which ligament runs along the anterior surface of the vertebral bodies?
Posterior longitudinal ligament
Ligamentum flavum
Anterior longitudinal ligament
Supraspinous ligament
The anterior longitudinal ligament runs down the anterior surfaces of the vertebral bodies from the occiput to the sacrum, resisting hyperextension. The posterior longitudinal ligament is on the posterior aspect of the bodies, within the vertebral canal. Learn more.
Which ligament forms the posterior wall of the vertebral canal?
Posterior longitudinal ligament
Supraspinous ligament
Ligamentum flavum
Anterior longitudinal ligament
The posterior longitudinal ligament lies inside the vertebral canal along the posterior aspects of the vertebral bodies and discs, preventing posterior disc herniation. It differs from the ligamentum flavum, which connects laminae. Learn more.
The annulus fibrosus is primarily composed of what tissue?
Elastic cartilage
Concentric lamellae of fibrocartilage
Hyaline cartilage
Dense regular connective tissue
The annulus fibrosus consists of concentric lamellae of fibrocartilage, rich in type I collagen, providing tensile strength and containment of the nucleus pulposus. It is not hyaline or elastic cartilage. Learn more.
Which vertebral joints are synovial plane joints located between the articular processes?
Uncovertebral joints
Facet (zygapophyseal) joints
Costovertebral joints
Sacroiliac joints
Facet joints, or zygapophyseal joints, are synovial plane joints between superior and inferior articular processes of adjacent vertebrae, allowing sliding movements and guiding spinal motion. Learn more.
What is the ring of hyaline cartilage that covers the superior and inferior surfaces of vertebral bodies called?
Vertebral endplate
Lamina
Pedicle
Spinous process
Vertebral endplates are thin layers of hyaline cartilage covering the top and bottom of each vertebral body, serving as the interface between the disc and bone and allowing nutrient diffusion. Learn more.
Which ligament functions to limit flexion of the vertebral column?
Anterior longitudinal ligament
Ligamentum nuchae
Supraspinous ligament
Anterior sacrococcygeal ligament
The supraspinous ligament runs along the tips of spinous processes and resists separation during flexion, aiding in limiting forward bending. It becomes continuous with the nuchal ligament in the cervical region. Learn more.
What is the anatomical term for the joints between the uncinate processes of C3–C7 vertebrae?
Costotransverse joints
Zygapophyseal joints
Uncovertebral (Luschka) joints
Interspinous joints
Uncovertebral, or Luschka, joints form between uncinate processes of C3–C7 and adjacent vertebral bodies, guiding cervical spine movements and potentially contributing to foraminal narrowing. Learn more.
Which structure primarily prevents posterior herniation of the nucleus pulposus into the spinal canal?
Posterior longitudinal ligament
Annulus fibrosus
Ligamentum flavum
Transverse ligament
The annulus fibrosus encircles the nucleus pulposus with tough concentric fibrocartilage layers, preventing it from bulging or herniating posteriorly. The posterior longitudinal ligament also offers support, but the annulus is the primary containment structure. Learn more.
Disc herniations most commonly occur in which direction?
Lateral
Posterior
Posterolateral
Anterior
Most disc herniations occur posterolaterally where the annulus fibrosus is thinner and not reinforced by the posterior longitudinal ligament, allowing nucleus pulposus material to protrude and potentially impinge on nerve roots. Learn more.
What is the name of the fibrocartilaginous plates between vertebral bodies and discs?
Annulus fibrosus
Cartilaginous endplates
Nucleus pulposus
Vertebral rim cartilage
Cartilaginous endplates cover the superior and inferior surfaces of vertebral bodies, interfacing with the disc and facilitating nutrient diffusion into the avascular disc. They are distinct from the annulus fibrosus and nucleus pulposus. Learn more.
Which ligament connects adjacent laminae of the vertebrae?
Interspinous ligament
Ligamentum flavum
Supraspinous ligament
Intertransverse ligament

Schmorl's nodes occur when the nucleus pulposus herniates vertically through defects in the vertebral endplate into the adjacent vertebral body, often asymptomatic but visible radiographically. Learn more.
In which region of the vertebral column is the disc height relative to vertebral body height greatest?
Thoracic
Cervical
Lumbar
Sacral
The cervical discs have the greatest height-to-body-height ratio, facilitating a wide range of motion. Lumbar discs are thick but proportionally less so, and thoracic discs are the thinnest relative to vertebral bodies. Learn more.
Which spinal ligament has the highest elastin content?
Posterior longitudinal ligament
Anterior longitudinal ligament
Ligamentum flavum
Interspinous ligament
Ligamentum flavum contains a high proportion of elastic fibers, allowing it to stretch during flexion and rebound during extension, maintaining tension and stability of the vertebral canal. Learn more.
During spinal extension, which ligament may buckle and compress the spinal cord if hypertrophied?
Posterior longitudinal ligament
Ligamentum flavum
Supraspinous ligament
Interspinous ligament
Hypertrophy or thickening of the ligamentum flavum can lead to buckling into the spinal canal during extension, contributing to spinal stenosis and cord or nerve root compression. Learn more.

Cheat Sheet
Anatomy of Intervertebral Discs -
Each intervertebral disc consists of a gelatinous nucleus pulposus encased by a fibrous annulus fibrosus, which together allow spine flexibility and absorb shock - key facts you'll need for the intervertebral joints quiz. A handy mnemonic is "Nurture the Nucleus, Appreciate the Annulus" to remember their roles. University research shows the nucleus handles compressive loads while the annulus prevents bulging during movement.
Key Spinal Ligaments -
The anterior and posterior longitudinal ligaments (ALL and PLL) run along vertebral bodies to limit hyperextension and hyperflexion, respectively, bolstering spinal stability - common topics on the spinal ligaments quiz. Ligamentum flavum, interspinous, and supraspinous ligaments form the posterior tension band, with elastic fibers in ligamentum flavum aiding upright posture. Orthopedic literature emphasizes their role in protecting neural elements by guiding vertebral motion.
Zygapophysial Joint Mechanics -
Facet joints are synovial plane joints between superior and inferior articular processes, permitting gliding motions that differ by region: horizontal in cervical for rotation, vertical in lumbar for flexion/extension - essential knowledge for vertebral joint anatomy. Remember "C-spine rotates, L-spine flexes" as a quick guide to their orientation. Cadaveric studies confirm facet joint orientation dictates spinal range of motion and load distribution.
Load Distribution & Intradiscal Pressure -
Intradiscal pressure can exceed 0.5 MPa when lifting heavy weights, and disc height influences force distribution across spinal levels - fun disc trivia you'll see on intervertebral disc trivia sections. Research shows a 20° forward flexion increases anterior disc pressure by up to 50%, highlighting posture's impact on spinal health. A practical tip is maintaining neutral spine alignment to evenly distribute loads and minimize injury risk.
Spinal Curvatures & Mnemonics -
The spine's natural curves - cervical lordosis, thoracic kyphosis, lumbar lordosis - function like a spring to absorb shocks and maintain balance, a concept often tested in spine anatomy quiz. Use "Lord KY LO," which stands for Lordosis-Kyphosis-Lordosis order from top to bottom, to retain their sequence. Clinical anatomy sources explain that deviations from these curves can lead to conditions like kyphosis or hyperlordosis.
