A two-headed muscle. The term is often used as an abbreviation for biceps brachii.

One of the muscles for bending the elbow, and therefore a determinant of strength for lifting — the glass to the lips, or loads a great deal heavier. Being a discrete and visible muscle, especially when well-developed, it is often displayed as the epitomy of body-building. It is so-named because it has two ‘heads’; both are attached to the scapula (shoulder blade) above the shoulder joint. Each ‘head’ swells into the dual belly of the muscle; this gathers below into a short tendon spanning the front of the elbow joint to be attached on the upper end of the radius.

— Stuart Judge

See musculo-skeletal system.

A two-headed muscle. See also biceps brachii, biceps femoris.

A muscle having two heads. There is a biceps muscle in both fore- and hindlimbs. See also bicipital.

• b. brachii — is a large fusiform muscle lying on the cranial surface of the humerus. Its function is to flex the elbow and integrate the actions of the shoulder and elbow. A medial displacement of the tendon of origin has been reported in dogs, causing a weight-bearing lameness.
• b. femoris — a large muscle of the caudolateral part of the thigh. Its function is to extend the hindlimb when propelling the body, during rearing or kicking. All of the joints are affected except those of the digit.
— Rupture of the muscle causes acute hindlimb lameness in cattle. Resembles an intermittent upward fixation of the patella, with extension of the stifle and hock.
• b. reflex — is elicited in dogs by striking a finger placed on the biceps tendon on the craniomedial aspect of the elbow. An active reflex indicates intact spinal cord segments and nerve roots C6–8 and musculocutaneous nerve. It becomes exaggerated in disease of the upper motor neuron.
• b. tendon ossification — causes lameness in the horse. Is radiographically apparent.
