| 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) |

| accessory volar ligaments | The fibrocartilaginous plates, one located on the anterior aspect of each metacarpophalangeal and interphalangeal joint, that are firmly attached to the bases of the phalanges and the heads of the next proximal bones; they are grooved to accommodate the long flexor tendons. Synonym: ligamenta palmaria, accessory volar ligaments. (05 Mar 2000) |
| alar ligaments | One of a pair of short stout bands that extends from the side of the dens of the axis to the tubercle on the medial aspect of the occipital condyle. Synonym: check ligaments of odontoid. Synonym: alar folds. (05 Mar 2000) |
| annular ligaments of the trachea | The fibrous membranes that connect adjacent tracheal cartilages. Synonym: ligamenta annularia trachealia, ligamenta trachealia. (05 Mar 2000) |
