| tarsal cyst | Also called a Meibomian cyst or a chalazian. A tarsal cyst is an inflammation of the oil gland of the eyelid. (12 Dec 1998) |
|---|---|
| tarsal fold | The fold marking the attachment of the levator palpebrae superioris muscle into the skin of the upper eyelid. (05 Mar 2000) |
| tarsal glands | Sebaceous glands embedded in the tarsal plate of each eyelid, discharging at the edge of the lid near the posterior border. Their secretions create a lipid barrier along the margin of the eyelids which contains the normal secretions in the conjunctival sac by preventing the watery fluid from spilling over the barrier when the eye is open. Synonym: glandulae tarsales, meibomian glands, palpebral glands. (05 Mar 2000) |
| tarsal joints | The synovial joints which unite the tarsal bones. Synonym: articulationes intertarseae, intertarsal articulations, tarsal joints. (05 Mar 2000) |
| tarsal plates | See: superior tarsus, inferior tarsus. (05 Mar 2000) |
| tarsal tunnel syndrome | <syndrome> Compression of the posterior tibial nerve caused by thickening of the laciniate ligament or by gouty or arthritic deposits around the ankle joint leading to symptoms of pain or paresthesia over the sole of the foot. (12 Dec 1998) |
| transverse tarsal articulation | The synovial joints between the talus and navicular bone medially and the calcaneus and navicular bones laterally which act as a unit in allowing the front of the foot to pivot relative to the back of the foot about the longitudinal axis of the foot, contributing to the total inversion and eversion movements. Synonym: articulatio tarsi transversa, Chopart's joint, midtarsal joint, transverse tarsal articulation. (05 Mar 2000) |

| lateral tarsal artery | <anatomy, artery> Origin, dorsalis pedis; distribution, tarsal joints and extensor digitorum brevis muscle; anastomoses, arcuate, peroneal, lateral plantar, anterior lateral malleolar. Synonym: arteria tarsea lateralis. (05 Mar 2000) |
| anterior interosseous artery | <anatomy, artery> Origin, common interosseous; distribution, deep parts of the forearm anteriorly; anastomoses, posterior interosseous. Synonym: arteria interossea anterior, arteria interossea volaris, volar interosseous artery. (05 Mar 2000) |
| anterior interosseous nerve | <anatomy, nerve> A branch of the median arising in elbow region, running on interosseous membrane, supplying the flexor pollicis longus, part of flexor digitorum profundus and the pronator quadratus muscles, as well as radiocarpal and intercarpal joints. Synonym: nervus interosseus anterior, ramus profundus nervi radialis, nervus antebrachii anterior, anterior antebrachial nerve, volar interosseous nerve. (05 Mar 2000) |
| palmar interosseous artery | <anatomy, artery> One of the three arteries springing from the deep palmar arch and running in the three medial interosseous spaces; they anastomose with the common palmar and dorsal metacarpal arteries. Synonym: arteria metacarpea palmaris, palmar interosseous artery. (05 Mar 2000) |
| palmar interosseous muscle | <anatomy> Three muscles in the hand; origin, first: ulnar side of second metacarpal; second and third: radial sides of fourth and fifth metacarpals; insertion, first: into ulnar side of index; second and third: into radial sides of ring and little fingers; action, adducts fingers toward axis of middle finger; nerve supply, ulnar. See: flexor pollicis brevis muscle. Synonym: musculus interosseus palmaris, musculus interosseus volaris. (05 Mar 2000) |
| recurrent interosseous artery | <anatomy, artery> Origin, posterior interosseous; distribution, elbow joint; anastomoses, branches of profunda brachii and inferior ulnar collateral, i.e., articular vascular network of elbow. Synonym: arteria interossea recurrens. (05 Mar 2000) |
| volar interosseous artery | <anatomy, artery> Origin, common interosseous; distribution, deep parts of the forearm anteriorly; anastomoses, posterior interosseous. Synonym: arteria interossea anterior, arteria interossea volaris, volar interosseous artery. (05 Mar 2000) |
