| mucoid medial degeneration | Loss of elastic and muscle fibres in the aortic media, with accumulation of mucopolysaccharide, sometimes in cystlike spaces between the fibres; a disease of unknown cause, which may be inherited and which predisposes to dissecting aneurysms. Synonym: Erdheim disease, medionecrosis aortae idiopathica cystica, medionecrosis of the aorta, mucoid medial degeneration. (05 Mar 2000) |

| posterior medial nucleus of thalamus | Medial part of the ventrobasal nuclear complex. See: ventral posterior nucleus of thalamus. Synonym: nucleus ventralis posteromedialis thalami. (05 Mar 2000) |
| posterior superior medial nasal branches of pterygopalatine ganglion | Usually branches of the nasopalatine nerve to posterior superior nasal septum. Synonym: rami nasales posteriores superiores mediales ganglii pterygopalatini. (05 Mar 2000) |
| cystic medial necrosis | Loss of elastic and muscle fibres in the aortic media, with accumulation of mucopolysaccharide, sometimes in cystlike spaces between the fibres; a disease of unknown cause, which may be inherited and which predisposes to dissecting aneurysms. Synonym: Erdheim disease, medionecrosis aortae idiopathica cystica, medionecrosis of the aorta, mucoid medial degeneration. (05 Mar 2000) |
| subcutaneous bursa of medial malleolus | <anatomy> The bursa between the medial malleolus and the skin. Synonym: bursa subcutanea malleoli medialis, subcutaneous bursa of medial malleolus. (05 Mar 2000) |
| nucleus of medial geniculate body | The nerve cell groups composing the medial geniculate body (corpus geniculatum mediale). Synonym: nucleus corporis geniculati medialis. (05 Mar 2000) |
| superficial branch of the medial plantar artery | <anatomy, artery> Gives rise to superficial digital arteries of medial three toes. Synonym: ramus superficialis arteriae plantaris medialis. (05 Mar 2000) |
| superior medial genicular artery | <anatomy, artery> Origin, popliteal; distribution, knee joint; anastomoses, descending genicular, lateral superior genicular, i.e., the articular vascular network of the knee. Synonym: arteria genus superior medialis, medial superior genicular artery. (05 Mar 2000) |
| decussation of medial lemniscus | The intercrossing of the fibres of the left and right medial lemniscus ascending from the gracile and cuneate nuclei, immediately rostral to the level of the decussation of the pyramidal tracts in the medulla oblongata. Synonym: decussatio lemniscorum, decussatio sensoria, decussation of the fillet, sensory decussation of medulla oblongata. (05 Mar 2000) |
| deep branch of the medial femoral circumflex artery | <anatomy, artery> Distributed to posterior aspect of femoral head and neck. Synonym: ramus profundus arteriae circumflexae femoris medialis. (05 Mar 2000) |
| deep branch of the medial plantar artery | <anatomy, artery> Branch running deep to abductor hallucis, supplying it and the flexor hallucis brevis muscle deep to the artery and the skin of the medial side of the distal foot. Synonym: rami profundi arteriae circumflexae femoris medialis. (05 Mar 2000) |
| inferior medial genicular artery | <anatomy, artery> Origin, popliteal; distribution, knee joint; anastomoses, anterior and posterior tibial recurrent and medial superior genicular, i.e., articular vascular network of knee.

| 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) |
| accessory nerve | <anatomy, nerve> The accessory nerve enervates the sternocleidomastoid muscles and the trapezius muscles. Lesions of the eleventh result in drooping of the shoulder and inability to rotate the head away from the affected side. Synonym: cranial nerve XI. (27 Sep 1997) |
