The =biceps brachii= is fusiform and not greatly developed. Its tendon
of origin is rounded and passes through the capsule of the shoulder
joint. The tendon of insertion is bifid, ending on the radius and ulna.
The =brachialis= is well developed, and also ends on the radius and
ulna.
The =tensor fascias antibrachii= resembles that of the horse.
The =long head of the triceps= is divided into two parts, except at its
distal end, under which there is a synovial bursa. The =external head=
is inserted into a crest on the outer surface of the olecranon by a thin
tendon, under which there is a bursa. The =internal head= arises near
the head of the humerus, beneath the coraco-brachialis.
There are two =anconei=.
