| superior vestibular area | The area in the fundus of the internal acoustic meatus superior to the transverse crest through which the superior part of the vestibular nerve passes to reach the macula utriculus and the ampullae of the anterior and lateral saemicircular ducts. Synonym: area vestibularis superior. (05 Mar 2000) |

| 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) |
| anal region | The posterior portion of the perineal region through which the anal canal opens; bounded by a line through both isehial tuberosities, the sacrotuberous ligaments and the coccyx. Synonym: regio analis, anal region. (05 Mar 2000) |
| ankle region | The region of the lower limb between the leg (crus) and the foot (pes). Synonym: regio talocruralis. (05 Mar 2000) |
| anterior antebrachial region | The area between the radial and ulnar borders of the forearm anteriorly. Synonym: facies antebrachialis anterior, regio antebrachialis anterior, anterior antebrachial region, anterior surface of forearm, facies anterior antebrachii. (05 Mar 2000) |
| anterior brachial region | The anterior region of the arm. (05 Mar 2000) |
| anterior carpal region | The anterior part of the wrist. Synonym: regio carpalis anterior. (05 Mar 2000) |
