BRACHIALIS, in anatomy, an oblong, thick, and broad ffluf- ' cle, lying immediately on the anterior part of the lower half of the os humeri ; the upper part of it is forked, or Hoped, and, at the bending of the joint of the elbow, the lower part of it contracts. It is fixed to the furface of the os humeri by a great number of flefhy fibres, from the lower infertion of the deltoides almoft down to the two foflae at the lower extremity of the bone, and from one edge of the forefide of this lower extremity to the other. The fibres are for the moft part lon- gitudinal ; thofe ncareft the furface of the mufcle being lon^eft, the more internal growing gradually fhorter. The lateral fibres are a little oblique, and this obliquity in- creafes as they defcend lower. Thefe lateral fibres are partly fixed in the intermufcular ligaments of the os humeri ; of which ligaments, that which lies toward the internal condyle, is longer and broader than that toward the external. The loweft of thefe fibres are very oblique, and form on each fide a kind of fmall feparate fafciculus. In patting over the joint, all thefe fibres contract in breadth, and afterwards end in a ftrong flat tendon, inferted in the mufeular imprefiion, which is directly below the coronoide apophyfis of the ulna. The ftoped or forked extremity of this mufcle embraces the large tendon of the deltoides; the internal part of the fork meets the inferior infertion of the coraco-br-achialis, and the forefide of the whole mufcle is covered by the two flefhy bo- dies of the biceps.
