| fossa jugularis | An oval depression near the posterior border of the petrous portion of the temporal bone, medial to the styloid process, in which lies the beginning of the internal jugular vein (jugular bulb). Synonym: fossa jugularis. (05 Mar 2000) |

| radix ventralis | The motor root of a spinal nerve. Synonym: radix anterior, radix motoria, anterior root, motor root, radix ventralis. (05 Mar 2000) |
| rami ventralis | Rami ventralis See: ventral primary rami of cervical spinal nerves, ventral primary rami of lumbar spinal nerves, ventral primary rami of sacral spinal nerves, ventral primary ramus of spinal nerve. (05 Mar 2000) |
| ramus ventralis nervi spinalis | <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) |
| ventralis | Synonym: ventral. Origin: L. (05 Mar 2000) |
| pars ventralis pontis | The large ventral part of the pons occupied by the nuclei pontis, traversed longitudinally by corticopontine, corticobulbar, and corticospinal fibres, and transversely by pontocerebellar fibres. Pontocerebellar fibres converging laterally form the middle cerebellar peduncle or brachium pontis. Synonym: pars ventralis pontis, anterior part of pons, basilar part of pons, pars basilaris pontis. (05 Mar 2000) |
| pedunculus thalami ventralis | The massive system of fibre bundles emerging through the ventral, lateral, and anterior borders of the thalamus to join the internal capsule and parts of the corona radiata; it contains the fibres reciprocally connecting the ventral thalamic nuclei with the precentral and postcentral gyri of the cerebral cortex. Synonym: pedunculus thalami ventralis. (05 Mar 2000) |
| commissura ventralis alba | A narrow band of white substance bordering on the anterior median fissure of the spinal cord in front of the anterior gray commissure, and consisting of nerve fibres crossing over from one half of the spinal cord to the other. Synonym: commissura alba, anterior white commissure, commissura ventralis alba, ventral white column. (05 Mar 2000) |
| musculus sacrococcygeus ventralis | <anatomy> An inconstant muscle on the pelvic surfaces of the sacrum and coccyx, the remains of a portion of the tail musculature of lower animals. Synonym: musculus sacrococcygeus ventralis, musculus sacrococcygeus anterior, ventral sacrococcygeal muscle. (05 Mar 2000) |
| norma ventralis | External aspect of the base of skull Synonym: norma basilaris, basis cranii externa, norma inferior, norma ventralis. (05 Mar 2000) |
| sulcus ventralis | A deep median fissure on the anterior surface of the spinal cord. Synonym: fissura mediana anterior medullae spinalis, anteromedian groove, sulcus ventralis. (05 Mar 2000) |
| nucleus ventralis anterior thalami | The most rostral of the subdivisions of the ventral nucleus, receiving projections from the globus pallidus and projecting to the premotor and frontal cortex. Synonym: nucleus ventralis anterior thalami. (05 Mar 2000) |
| nucleus ventralis corporis trapezoidei | A cell group embedded among the fibres of the trapezoid body, the major decussation of the central auditory pathway, in the lower pons. The nucleus receives fibres from the contralateral cochlear nuclei and contributes fibres to the ascending auditory system or lateral lemniscus. Synonym: nucleus ventralis corporis trapezoidei. (05 Mar 2000) |
| nucleus ventralis intermedius thalami | The composite middle third of the ventral nucleus receiving in its various parts distinctive projections from the contralateral half of the cerebellum (by way of the superior cerebellar peduncle) and the ipsilateral globus pallidus; nearly all parts of the nucleus projects to the motor cortex. Synonym: nucleus ventralis intermedius thalami, nucleus ventralis lateralis, ventral lateral nucleus of thalamus. (05 Mar 2000) |
| nucleus ventralis lateralis | The composite middle third of the ventral nucleus receiving in its various parts distinctive projections from the contralateral half of the cerebellum (by way of the superior cerebellar peduncle) and the ipsilateral globus pallidus; nearly all parts of the nucleus projects to the motor cortex. Synonym: nucleus ventralis intermedius thalami, nucleus ventralis lateralis, ventral lateral nucleus of thalamus. (05 Mar 2000) |
