| deep part of flexor retinaculum | <anatomy> A strong fibrous band crossing the front of the carpus and binding down the flexor tendons of the digits and the flexor carpi radialis tendon and the median nerve; in so doing it creates the carpal tunnel. Synonym: retinaculum flexorum, deep part of flexor retinaculum, flexor retinaculum, ligamentum carpi transversum, ligamentum carpi volare, volar carpal ligament. (05 Mar 2000) |

| sympathetic part | <anatomy, physiology> One of the two divisions of the vertebrate autonomic nervous system (the other being the parasympathetic nervous system). The sympathetic preganglionic neurons have their cell bodies in the thoracic and lumbar regions of the spinal cord and connect to the paravertebral chain of sympathetic ganglia. Innervate heart and blood vessels, sweat glands, viscera and the adrenal medulla. most sympathetic neurons, but not all, use noradrenaline as a post ganglionic neurotransmitter. (19 Jan 1998) |

| descending part of facial canal | Second portion of the facial canal, after the horizontal parts, beginning at the posterior end of the lateral crus where the canal begins to descend. It runs vertically downward, ending at the stylomastoid foramen. Anteriorly, the descending part of the facial canal communicates with the tympanic cavity via the canaliculus for the nerve to the stapedius muscle and the posterior canaliculus of the chorda tympani.

| distal part of anterior lobe of hypophysis | The larger part of the adenohypophysis composed of cords of epithelial cells individually specialised to secrete various tropic hormones that exert their effect on several target organs in the body. The secretory activity of these cells is under the control of either releasing or inhibiting factors elaborated by hypothalamic neurons and transported to the adenohypophysis by the hypothalamo-hypophysial portal system. Synonym: pars distalis. (05 Mar 2000) |
| dorsal part of pons | The part of the pons bounded laterally by the middle cerebellar peduncles and anteriorly by the ventral part of pons; it is continuous with the tegmentum of the mesencephalon and contains long tracts such as the medial and lateral lemnisci, cranial nerve nuclei, and reticular formation. Synonym: pars dorsalis pontis, tegmentum of pons. (05 Mar 2000) |
| quadrate part of liver | The part of the medial segment of the liver which includes the quadrate lobe. Synonym: pars quadrata hepatis. (05 Mar 2000) |
| inferior part | The lowermost portion of a structure relative to the other parts; portion closest to the soles of the feet. See: inferior part of duodenum, inferior part of lingular branch of left pulmonary vein, inferior part of vestibular ganglion. Synonym: pars inferior. (05 Mar 2000) |
