The lower extremity is some-what irregular, and articulates withtlie four bones comprising the upperrow of the knee. In front there arethree grooves over which three ten-dons play in passing down the limbto their points of insertion. Eachtendon is supplied with a synovialmembrane to facilitate its move-ments over the bone during flexionand extension of the knee. Ulna (fig. 300).—The ulna is along tapering bone, united by ossi-fication to the outer and posteriorsurface of the radius. Its superiorextremity is of considerable lengthand thickness, and projects from thehead of the radius in an upwardand backward direction. This is theelbow or olecranon ^>?oce*.s. Infiont it presents a smooth surface,which articulates with the groovebetween the condyles of the humerus,and also a hooked projection for-ward termed the hcah. CARPUS OR KNEE

This (fig. 301) is the analogue of the wrist of man. It is made up ofseven, sometimes eight, small irregular bones arranged in two rows ofthree each, one resting upon the other, with the seventh bone (pisiform)situated at the posterior and outer part of the upper row. THE FORK LLMB 197 The bones of tlie upper row,enumerating them from withinoutward, are the scaphoid, lunar,cuneiform, and the pisiform be-hind; those of the lower roware the trapezoid, magnum, andunciform. Sometimes a fourth,termed the trapezium, is foundat the inner and posterior partof the lower row. All these bones are unitedby short strong ligaments. Attheir several points of contacttheyare covered with articular car-tilage or gristle, and enclosed ina synovial capsule. Altogetherthe knee is admirably adapted,by its many parts, to
