| pars superior ganglii vestibularis | Rostral part, the superior part of the vestibular ganglion that receives fibres from the maculae of the utricle and the saccule and the ampullae of the anterior and lateral saemicircular ducts. Synonym: pars superior ganglii vestibularis. (05 Mar 2000) |
|---|---|
| pars vestibularis nervi vestibulocochlearis | <anatomy, nerve> The vestibular part of the acoustic (8th cranial) nerve. The vestibular nerve fibres arise from neurons of scarpa's ganglion and project peripherally to vestibular hair cells and centrally to the vestibular nuclei of the brainstem. These fibres mediate the sense of balance and head position. (12 Dec 1998) |
| glandula vestibularis major | One of two mucoid-secreting tubuloalveolar glands on either side of the lower part of the vagina, the equivalent of the bulbourethral glands in the male; ensheathed with vestibular bulbs by ischiocavernosus muscles. Thus erection and muscle contraction cause secretion into vestibule of vagina. Synonym: glandula vestibularis major, Bartholin's gland, Duverney's gland, Tiedemann's gland, vulvovaginal gland. (05 Mar 2000) |
| membrana vestibularis | The membrane separating the cochlear duct from the vestibular canal; it consists of squamous epithelial cells with microvilli toward the ductus, a basement membrane, and a thin layer of connective tissue toward the scala. Synonym: membrana vestibularis, paries vestibularis ductus cochlearis, Reissner's membrane, vestibular wall of cochlear duct. (05 Mar 2000) |
| plica vestibularis | 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) |
| nervus vestibularis | <anatomy, nerve> The vestibular part of the acoustic (8th cranial) nerve. The vestibular nerve fibres arise from neurons of scarpa's ganglion and project peripherally to vestibular hair cells and centrally to the vestibular nuclei of the brainstem. These fibres mediate the sense of balance and head position. (12 Dec 1998) |
| nucleus vestibularis | One of a group of four main nuclei that includes: the lateral vestibular nucleus (Deiters' nucleus), medial vestibular nucleus (Schwalbe's nucleus), superior vestibular nucleus (Bechterew's nucleus), and inferior vestibular nucleus, located in the lateral region of the hindbrain beneath the floor of the rhomboid fossa. They receive primary fibres of the vestibular nerve, are reciprocally connected with the flocculonodular lobe of the cerebellum, and project by way of the medial longitudinal fasciculus to the abducens, trochlear, and oculomotor nuclei and to the ventral horn of the spinal cord. The lateral vestibular nucleus projects to the ipsilateral ventral horn of the spinal cord by the vestibulospinal tract. Synonym: nucleus vestibularis. (05 Mar 2000) |
| labyrinthus vestibularis | The portion of the membranous labyrinth located within the saemicircular canals and the vestibule of the osseous labyrinth. It is surrounded with perilymph and involved with vestibular functions. Synonym: labyrinthus vestibularis. (05 Mar 2000) |
| apex cuspidis dentis | The tip of the peaklike projections from the crown of a tooth. Synonym: apex cuspidis dentis. (05 Mar 2000) |
| apex dentis | The tip of the dens of the axis to which is attached the apical ligament of the dens. Synonym: apex dentis. (05 Mar 2000) |
| apex radicis dentis | The tip of a tooth root, the part farthest from the incisal or occlusal side. Synonym: apex radicis dentis, root apex, root tip. (05 Mar 2000) |
| canalis radicis dentis | The chamber of the dental pulp lying within the root portion of a tooth. Synonym: canalis radicis dentis, marrow canal, pulp canal. (05 Mar 2000) |
| radix dentis | That part of a tooth below the neck, covered by cementum rather than enamel, and attached by the periodontal ligament to the alveolar bone. Synonym: radix dentis, radix, root. (05 Mar 2000) |
| papilla dentis | Mesodermal tissue enclosed in the invaginated portion of the epithelial enamel organ and giving rise to the dentin and pulp. (12 Dec 1998) |
| cavitas dentis | The central hollow of a tooth consisting of the crown cavity and the root canal; it contains the fibrovascular dental pulp and is lined throughout by odontoblasts. Synonym: cavitas dentis, cavity of tooth, cavum dentis. (05 Mar 2000) |
