Re: Dr Evey's True/False Questions - Suboccipital region

Comments:
: : 1) The vertebral foramen transmits the spinal nerve from the spinal canal to the paravertebral region. : : F - the intervertebral foramen does this. The vertebral foramen transmits the spinal cord from the cranium to the sacral canal : Agree. "Sacral canal?" To the sacral hiatus. : : 2) The spinal canal has both bony and fibrous boundaries. : : T - bony from the vertebral bodies, fibrous from the posterior long. lig. and the ligamentum flavum : Agree. Bony from the pedicles as well. : : 3) The ligamentum flavum is named for its yellow appearance. : : T : Agree. : : 4) The obliques capitis inferioris rotates the head to the opposite side. : : F - same side : Agree. : : 5) The rectus capitis posterior major flexes the neck. : : F - extends : Agree. Extends the head. : : 6) There are 7 cervical nerves and 8 cervical vertebrae. : : T : False. Reverse. : : 7) Obliques capitis superioris rotates the head to the same side. : : T : Agree. : : 8) The suboccipital nerve enters the back inferior to the occipital bone and superior to the atlas. : : T : Agree. : : 9) At the superior nuchal line the greater occipital nerve is medial to the occipital artery. : : T : Agree. : : 10) The nuchal ligament limits flexion of the neck. : : T : Agree. : : 11 )A lesion of the suboccipital nerve would make extension of the neck impossible. : : F - lean back and gravity will do this for you...and splenius capitis could still help : Agree. Semispinalis cervicis/capitus, trapezius, longissimus, and so on. : : 12) A lesion of the occipital nerve would cause paresthesia or anesthesia of the scapular region. : : T : False. Odd question. There is not an named nerve called the occipital nerve. Occipital artery. : : 13) The ligamentum flavum extends between adjacent lamina. : : T : Agree. : : 14) The interspinous ligament extends between adjacent pedicles. : : F - between adjacent spinous processes : Agree. : : 15) Cerebral spinal fluid is located immediately deep to ligamentum flavum, between it and dural mater. : : F - between arachnoid and pia mater : Agree. : : 16) Spinal nerves can be anesthetized by injections into the epidural space. : : T : Agree. : : 17) The posterior longitudinal ligament has lateral extensions that help to reinforce the intervertebral disk. : : T : Agree. : : 18) The nuchal ligament can be considered an extension of the supraspinous ligament into the neck region. : : T : Agree. : : 19) The vertebral artery lies on the superior surface of the transverse process of the axis in the groove for the vertebral artery. : : T : False might be the better answer. Vague question. The groove for that vertebral artery is of the arch, not the transverse process. Nevertheless, it could be argued that the vertebral artery briefly lies on the superior surface of the proximal transverse process. Not a particularly defensible position but I would not want to take it on. : : 20) The vertebral artery leaves the suboccipital triangle as it passes through the posterior atlantooccipital membrane. : : T? : Agree. : : 21) The greater occipital enters the back inferior to the obliques capitis inferioris muscle. : : T? - (nerve) : Agree. Nerve. I need to correct that. : : 22) From superficial to deep the greater occipital nerve passes through trapezius, then semispinalis capitis, and finally, splenius capitis. : : T? : False. Should be medial to splenius capitus. Further, if the dorsal ramus of C2 did pass through splenius capitus it would do so before semispinalis capitus if superficial/deep is specified.
