Question 1: The posterior atlanto-occipital membrane is a relatively thin sheet of tissue.
A. Yes
B. No
Explanation: The posterior atlanto-occipital membrane is described as a relatively thin sheet of tissue that runs between the posterior margin of the foramen magnum and the upper border of the posterior arch of the atlas.
Question 2: The main function of the ligamenta flava is to limit lateral flexion of the vertebral column.
A. Yes
B. No
Explanation: The main function of the ligamenta flava is to resist separation of the laminae during flexion and to aid in the extension of the vertebral column back to its erect anatomical posture. Limiting lateral flexion is the main function of the intertransverse ligaments.
Question 3: The anterior atlanto-axial membrane is primarily composed of elastic tissue.
A. Yes
B. No
Explanation: The study materials describe the anterior atlanto-axial membrane as a strong band that runs between the anterior arch of the atlas to the body of the axis. It does not mention that it is primarily composed of elastic tissue. Other ligaments like the ligamenta flava are noted to be composed of yellow elastic tissue, but this is not stated for the anterior atlanto-axial membrane.
Question 4: The nucleus pulposus, known for its gelatinous nature, forms the thick outer ring of the intervertebral disc.
A. Yes
B. No
Explanation: The study materials state that the annulus fibrosus is the thick outer ring of fibrous cartilage, while the nucleus pulposus is the inner, central gelatinous core.
Question 5: The supraspinous ligament, a cord-like band, runs along and connects the tips of the spinous processes from vertebra C7 to the sacrum, and it is continuous superiorly with the nuchal ligament.
A. Yes
B. No
Explanation: The study materials state: "Supraspinous ligament: is a cord-like band that runs along and connects the tips of the spinous processes from vertebra C7 to the sacrum. It is continuous superiorly with the nuchal ligament of the cervical region."
