Alternate Choice
- The connective tissue that anchors the spinal cord to the coccyx is called the cauda equina / filum terminale (circle one).
- The cervical / brachial (circle one) plexus innervates the muscles and skin of the shoulder.
- Nerves which innervate most of the deep muscles of the back and are responsible for the movement of the vertebral column arise from the dorsal / ventral (circle one) rami.
- Cranial nerves are named using the Roman numerals I through XII going from anterior- to posterior / posterior-to-anterior (circle one).
- The tibial nerve supplies the anterior / posterior (circle one) thigh.
- The tibial / common fibular (circle one) nerve supplies the anterior and lateral leg.
- The coccygeal / sacral (circle one) plexus supplies the pelvic floor.
- The phrenic nerve, which supplies the diaphragm, arises from the brachial / cervical (circle one) plexus.
- The intercostal nerves arise from the dorsal / ventral (circle one) rami.
- The radial nerve arises from the lateral / medial / posterior (circle one) cord.
- The connective tissue that anchors the spinal cord to the coccyx is called the conus medullaris / filum terminale (circle one).
- The thalamus / hypothalamus (circle one) is the major control center for maintaining homeostasis and regulating endocrine function.
- Motor areas of the cerebrum are located in the frontal / parietal (circle one) lobe(s).
- Nerve fiber tracts in the white matter are myelinated / non-myelinated (circle one).
- Ventral roots of the spinal cord consist of motor / sensory (circle one) neurons.
