THE BICEPS BRACHII• The biceps functions primarily as strong supinator of the forearm. This
action, which is aided by the supinator muscle, requires the elbow to be at least partially flexed.
• The biceps also functions as an powerful flexor of elbow joint, particularly when the forearm is supinated. Functionally, this action is performed when lifting an object, such as a bag of groceries or when performing a biceps curl.
• Both these movements are used when opening a bottle with a corkscrew: first biceps unscrews the cork (supination), then it pulls the cork out (flexion).
• If the elbow joint is fully extended, supination is then primarily carried out by the supinator muscle.
• Weak flexor of shoulder joint.

Cont….
• When the forearm is in pronation, the brachialis, brachioradialis, and supinator function to flex the forearm, with minimal contribution from the biceps brachii.
Flexed arm in the pronated position (left); with the biceps partially contracted and in a supinated position with the biceps more fully contracted, approaching minimum length (right.)

Cont….
• The brachialis muscle is innervated by the musculocutaneous nerve, which runs on its superficial surface, between it and the biceps brachii.
• Part of it is also innervated by the radial nerve (proprioceptive branch).
• Action: Most powerful flexor at elbow joint

Cont….
• The coracobrachialis draws the humerus forward (shoulder flexion) and towards the torso (shoulder adduction).

SUPRATROCHLEAR LYMPH NODES
• One or two supratrochlear lymph nodes lie in superficial fascia over the upper part of fascia.
• Are placed above the medial epicondyle of humerus, medial to the basilic vein.
• Their afferents drain the middle, ring, and little fingers, the medial portion of the hand, and the medial side of the forearm.
• Their efferents enter the lateral axillary lymph nodes

CLINICAL CORRELATES
• During blood pressure measurements, the stethoscope is placed over the brachial artery in the cubital fossa.
• The brachial pulse may be palpated in the cubital fossa also just medial to the tendon.
