| superior vestibular nucleus | 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) |
|---|---|
| inferior part of vestibular ganglion | The lower part of the vestibular ganglion that receives fibres from the macula of the saccule and the ampulla of the posterior saemicircular duct. Synonym: pars inferior ganglii vestibularis. (05 Mar 2000) |
| inferior vestibular area | The area of the fundus of the internal acoustic meatus inferior to the transverse crest through which the interior portion of the vestibular (saccular) nerve passes. Synonym: area vestibularis inferior. (05 Mar 2000) |
| inferior vestibular nucleus | Nucleus vestibularis inferior. See: vestibular nucleus. (05 Mar 2000) |
| intermediate part of vestibular bulb | A narrow median band that connects the two masses of erectile tissue (the bulbus vestibuli) on either side of the vaginal orifice. Synonym: pars intermedia commissura bulborum, commissura bulborum, intermediate part of vestibular bulb, pars intermedia bulborum. (05 Mar 2000) |
| external aperture of vestibular aqueduct | The external opening of the vestibular aqueduct on the posterior surface of the petrous part of the temporal bone near the groove for the sigmoid sinus. Synonym: apertura externa aqueductus vestibuli. (05 Mar 2000) |
| lateral vestibular nucleus | Nucleus vestibularis lateralis. See: vestibular nucleus. (05 Mar 2000) |
| lesser vestibular glands | A number of minute mucous glands opening on the surface of the vestibule between the orifices of the vagina and urethra. Synonym: glandulae vestibulares minores. (05 Mar 2000) |
| little fossa of the vestibular window | A depression on the medial wall of the middle ear which has the fenestra vestibulae (oval window) in its lower portion. Synonym: Huguier's sinus, little fossa of the vestibular window, little fossa of the vestibular round window. (05 Mar 2000) |
| abdominal canal | A passage in the lower anterior abdominal wall which in the male allows passage of the spermatic cord and in the female contains the round ligament. Because of the weakness it creates in the abdominal wall, it is the most frequent site for a hernia. (12 Dec 1998) |
| accessory canal | A channel leading from the root pulp laterally through the dentin to the periodontal tissue; may be found anywhere in the tooth root, but is more common in the apical third of the root. Synonym: lateral canal. (05 Mar 2000) |
| adductor canal | The space in middle third of the thigh between the vastus medialis and adductor muscles, converted into a canal by the overlying sartorius muscle. It gives passage to the femoral vessels and saphenous nerve, ending at the adductor hiatus. Synonym: canalis adductorius, Hunter's canal, subsartorial canal. (05 Mar 2000) |
| Alcock's canal | The space within the obturator internis fascia lining the lateral wall of the ischiorectal fossa that transmits the pudendal vessels and nerves. Synonym: canalis pudendalis, Alcock's canal. (05 Mar 2000) |
| alimentary canal | <anatomy> The digestive tract. (27 Sep 1997) |
| anal canal | The terminal portion of the alimentary canal; it extends from the pelvic diaphragm to the anal orifice. Synonym: canalis analis. (05 Mar 2000) |
