Synovial Sheath

	Synovial Sheath A synovial sheath is one of the two membranes of a tendon sheath which covers a tendon. The other membrane is the outer fibrous tendon sheath. The tendon invaginates the synovial sheath from one side so that the tendon is suspended from the membrane by the mesotendon, through which the blood vessels reach the tendon, in places where the range of movement is extensive. The mesotendon disappears or remains in the form of narrow tendinous bands as threads known as vincula tendina. The synovial sheath is found where the tendon passes under ligaments and through osseofibrous tunnels; their function is to reduce friction between the tendon and their surrounding structure. An example is the common synovial sheath for the flexor tendons of the hand.

	Tendon Sheath A tendon sheath is a layer of synovial membrane around a tendon. It permits the tendon to stretch and not adhere to the surrounding fascia. It contains a lubricating fluid (synovial fluid) that allows for smooth motions of the tendon during muscle contraction and joint movements.

	Vincula Tendina Within each osseo-aponeurotic canal, the tendons of the flexor digitorum superficialis and flexor digitorum profundus are connected to each other, and to the phalanges, by slender, tendinous bands, called vincula tendina. Structure There are around three to seven vincula for each flexor tendon. Vincula tendina can be classified into two types according to their morphology. The ''vincula brevia'' (short), which are two in number in each finger, and consist of triangular bands of fibers, one connecting the tendon of the flexor digitorum superficialis to the front of the first interphalangeal joint and head of the first phalanx, and the other the tendon of the flexor digitorum profundus The flexor digitorum profundus or flexor digitorum communis profundus is a muscle in the forearm of humans that flexes the fingers (also known as digits).

	Common Synovial Sheath For The Flexor Tendons The common flexor sheath of hand or the ulnar bursa is a synovial sheath in the carpal tunnel of the human hand. It contains tendons of the flexor digitorum superficialis and the flexor digitorum profundus, but not the flexor pollicis longus. The sheath which surrounds the flexor digitorum extends downward about halfway along the metacarpal bones, where it ends in blind diverticula around the tendons to the index, middle, and ring fingers. It is prolonged on the tendons to the little finger and usually communicates with the synovial sheath A synovial sheath is one of the two membranes of a tendon sheath which covers a tendon.
