- adj. Resembling a pea in size or shape.
- n. A small bone at the junction of the ulna and the carpus.
Century Dictionary and Cyclopedia
- Having the form of pea, as an ossification in tendons at joints; having a structure resembling peas. A variety of iron ore is called pisiform, from its being made up of small rounded masses about the size of a pea.
- n. In anatomy, a sesamoid bone, of about the size and shape of a pea, developed in the tendon of the flexor carpi ulnaris muscle of man and some other animals. It is generally reckoned as one of the carpal bones, making eight in all, in mau, but is not morphologically an element of the carpus. It is often of irregular shape, and sometimes one of the largest bones in the carpus, as in the horse. See also cuts under Artiodactyla, Perissodactyla, solidungulate, and hand.

Examples
“Whenever circumstances may call for placing a ligature on the ulnar artery, as it lies between the superficial and deep flexor muscles, in the region of I L M, Plate 16, the course of the vessel may be indicated by a line drawn from a central point of the forearm, an inch or so below the level of the inner condyle -- viz., the point F, and carried to the pisiform bone, T.”
“The ulnar nerve, D E, lies on the ulnar border of the artery, and both are in general to be found ranging along the radial side of the tendon of the flexor carpi ulnaris muscle, T, and the pisiform bone, G.”
“The two volar ligaments are strong fibrous bands; one, the pisohamate ligament, connects the pisiform to the hamate, the other, the pisometacarpal ligament, joins the pisiform to the base of the fifth metacarpal bone (Fig. 334).”
“There is a separate synovial membrane between the pisiform and triangular.”
“The articular capsule is a thin membrane which connects the pisiform to the triangular; it is lined by synovial membrane.”
“The ligaments connecting the pisiform bone are the articular capsule and the two volar ligaments.”
“The fifth runs between the adjacent margins of the triangular and pisiform bones.”
“This slip may be replaced by a muscular fasciculus arising from or near the pisiform.”
“The fibers end in a tendon, which occupies the anterior part of the lower half of the muscle and is inserted into the pisiform bone, and is prolonged from this to the hamate and fifth metacarpal bones by the pisohamate and pisometacarpal ligaments; it is also attached by a few fibers to the transverse carpal ligament.”
“The pisiform is about 1 cm. distal to the lower end of the ulna and just distal to the level of the styloid process of the radius; it is crossed by the uppermost crease which separates the front of the forearm from the palm of the hand.”
