| false vocal cord | One of the pair of folds of mucous membrane stretching across the laryngeal cavity from the angle of the thyroid cartilage to the arytenoid cartilage; they enclose a space called the rima vestibuli or false glottis. Synonym: plica vestibularis, false vocal cord, plica ventricularis, ventricular band of larynx, ventricular fold. (05 Mar 2000) |

| umbilical cord | The flexible structure, giving passage to the umbilical arteries and vein, which connects the embryo or foetus to the placenta. (12 Dec 1998) |
| lumbar cord | That part of the cord that consists of the five lumbar segments and gives rise to the five pairs of lumbar nerves. Synonym: pars lumbalis medullae spinalis. (05 Mar 2000) |
| accessory portion of spinal accessory nerve | <anatomy, nerve> The roots of the accessory nerve which arise from the medulla; the nerve fibres of the cranial root join the intracranial portion of the vagus nerve and are distributed to the pharyngeal plexus, providing the motor innervation of the soft palate (except the tensor veli palati) and the pharynx. Synonym: pars vagalis nervi accessorii, radices craniales, accessory portion of spinal accessory nerve, cranial roots, vagal part of accessory nerve, vagal part. (05 Mar 2000) |
| anterior spinal artery | <anatomy, artery> Origin, intracranial part of vertebral; distribution, spinal cord and pia mater; anastomoses, spinal of intercostal and lumbar arteries. Synonym: arteria spinalis anterior. (05 Mar 2000) |
| ganglia, spinal | Sensory ganglia located on the dorsal spinal roots within the vertebral column. The spinal ganglion cells are pseudounipolar. The single primary branch bifurcates sending a peripheral process to carry sensory information from the periphery and a central branch which relays that information to the spinal cord or brain. (12 Dec 1998) |
| ganglion cells of dorsal spinal root | Pseudounipolar nerve cell bodies in the ganglia of the dorsal spinal nerve roots; the sensory spinal nerves are composed of the peripheral axon branches of these sensory ganglion cell's, whereas the central axon branch of each such cell enters the spinal cord as a component of the dorsal root.

| ventral primary rami of cervical spinal nerves | See: ventral primary ramus of spinal nerve. Synonym: rami ventrales nervorum cervicalium. (05 Mar 2000) |
| ventral primary rami of lumbar spinal nerves | See: ventral primary ramus of spinal nerve. Synonym: rami ventrales nervorum lumbalium. (05 Mar 2000) |
| ventral primary rami of sacral spinal nerves | See: ventral primary ramus of spinal nerve. Synonym: rami ventrales nervorum sacralium. (05 Mar 2000) |
| ventral primary ramus of spinal nerve | <anatomy, nerve> The larger, anterolaterally-directed major terminal branch (with the dorsal primary ramus) of all 31 pairs of mixed spinal nerves, formed at the intervertebral foramen. Most ventral primary rami, especially those involved in the innervation of the limbs, participate in the formation of the major nerve plexuses (cervical, brachial, and lumbosacral) and lose their identities. Most in the thoracic region, however, remain separate from adjacent rami to become the intercostal and subcostal nerves. Ventral primary rami provide innervation to the anterolateral body wall and trunk. Nomina Anatomica lists ventral primary rami as "rami ventrales" for each group of spinal nerves: 1) cervical (nervorum cervicalium ), 2) thoracic (nervorum thoracicorum ), 3) lumbar (nervorum lumbalium ), 4) sacral (nervorum sacralium )m, and 5) coccygeal (nervi coccygei ). Synonym: ramus ventralis nervi spinalis, anterior primary division. (05 Mar 2000) |
| recurrent meningeal branch of spinal nerves | A branch from the initial (mixed) part of each spinal nerve passing in a recurrent fashion back through the intervertebral foramen to supply spinal meninges, the posterior longitudinal ligament, posterolateral periphery of the intervertebral disc, and periosteum of the vertebrae. Synonym: ramus meningeus nervorum spinalium, recurrent meningeal branch of spinal nerves, sinuvertebral nerves. (05 Mar 2000) |
| medullary spinal arteries | A large caliber spinal or radicular artery which courses centrally along a dorsal or ventral root, perhaps supplying it and the surrounding meninges in the fashion of any spinal/radicular artery, but which continues on to reach and anastomose with the anterior or posterior (longitudinal) spinal artery. Only 4-9 of the spinal arteries are medullary spinal arteries, found mainly in the lower cervical, lower thoracic and upper lumbar levels, the largest of which is the great radicular artery. (05 Mar 2000) |
| meningeal branch of spinal nerves | A branch from the initial (mixed) part of each spinal nerve passing in a recurrent fashion back through the intervertebral foramen to supply spinal meninges, the posterior longitudinal ligament, posterolateral periphery of the intervertebral disc, and periosteum of the vertebrae. Synonym: ramus meningeus nervorum spinalium, recurrent meningeal branch of spinal nerves, sinuvertebral nerves. (05 Mar 2000) |
| groove for spinal nerve | <anatomy, nerve> The laterally directed groove on the superior surface of the transverse processes of typical cervical vertebrae between the anterior and posterior tubercles along which the emerging spinal nerve passes. Synonym: sulcus nervi spinalis. (05 Mar 2000) |
