| TCNS | transcutaneous nerve stimulation/stimulator |
|---|---|
| TENS | toxic epidermal necrolysis syndrome; transcutaneous electrical nerve stimulation |
| TMNST | tethered median nerve stress test |
| TNS | total nuclear score; transcutaneous nerve stimulation; tumor necrosis serum |
| UN | ulnar nerve; undernourished; unilateral neglect; urea nitrogen; urinary nitrogen |
| fasciculus lateralis plexus brachialis | In the brachial plexus, the bundle of nerve fibres formed by the anterior divisions of the superior and middle trunks which is located lateral to the axillary artery. This cord gives off the lateral pectoral nerve and terminates by dividing into the musculocutaneous nerve and the lateral root of the median nerve. Synonym: fasciculus lateralis plexus brachialis. (05 Mar 2000) |
|---|---|
| fasciculus medialis plexus brachialis | In the brachial plexus, the bundle of nerve fibres formed by the anterior division of the inferior trunk which lies medial to the axillary artery; it gives off the medial pectoral nerve, the medial brachial cutaneous, and medial antebrachial cutaneous, nerves and end by dividing into the medial root of the median nerves and the ulnar nerve. Synonym: fasciculus medialis plexus brachialis. (05 Mar 2000) |
| fasciculus posterior plexus brachialis | In the brachial plexus, the bundle of nerve fibres formed by the posterior divisions of the upper, middle and lower trunks which lies posterior to the axillary artery; it gives rise to the upper and lower subscapular and thoracodorsal nerves, terminates by dividing into the axillary, and radial nerves. Synonym: fasciculus posterior plexus brachialis. (05 Mar 2000) |
| femoral plexus | An autonomic plexus surrounding the femoral artery, derived from the iliac plexus. Synonym: plexus femoralis. (05 Mar 2000) |
| ureteric plexus | The autonomic plexus derived from the coeliac plexus that accompanies the ureter. Synonym: plexus uretericus. (05 Mar 2000) |
| uterine venous plexus | The plexiform veins that lie along the sides of the uterus in the broad ligament. Synonym: plexus venosus uterinus. (05 Mar 2000) |
| uterovaginal plexus | A gangliated autonomic plexus on each side of the cervix of the uterus, derived from the inferior hypogastric plexus. Synonym: plexus uterovaginalis, Frankenhauser's ganglion, Lee's ganglion. (05 Mar 2000) |
| lateral cord of brachial plexus | In the brachial plexus, the bundle of nerve fibres formed by the anterior divisions of the superior and middle trunks which is located lateral to the axillary artery. This cord gives off the lateral pectoral nerve and terminates by dividing into the musculocutaneous nerve and the lateral root of the median nerve. Synonym: fasciculus lateralis plexus brachialis. (05 Mar 2000) |
| Leber's plexus | A small venous plexus in the eye between the venous sinuses of the sclera (of Schlemm) and the spaces of the iridocorneal angle (of Fontana). (05 Mar 2000) |
| lingual plexus | An autonomic plexus on the artery of this name, derived from the external carotid plexus. Synonym: plexus lingualis. (05 Mar 2000) |
| lumbar plexus | A nervous plexus, formed by the ventral rami of the first four lumbar nerves; it lies in the substance of the psoas muscle, a lymphatic plexus formed of about twenty lymph nodes and connecting vessels situated along the lower portion of the aorta and the common iliac vessels. Synonym: plexus lumbalis. (05 Mar 2000) |
| lumbosacral plexus | The lumbar and sacral plexuses taken together. The fibres of the lumbosacral plexus originate in the lumbar and upper sacral spinal cord (l1 to s3) and innervate the lower extremities. (12 Dec 1998) |
| lymphatic plexus | A plexus of lymphatic capillaries, usually without valves, that opens into one or more larger lymphatic vessels. Synonym: plexus lymphaticus. (05 Mar 2000) |
| abducens nerve | <anatomy, nerve> The 6th cranial nerve. The abducens nerve originates in the abducens nucleus of the pons and sends motor fibres to the lateral rectus muscles of the eye. Damage to the nerve or its nucleus disrupts horizontal eye movement control. (12 Dec 1998) |
| abducent nerve | <anatomy> The abducent nerve enervates a muscle which moves the eyeball. Lesions of the sixth cranial nerve result in deviation of the eyeball outward and double vision. Synonym: cranial nerve VI. (27 Sep 1997) |
