Ready to learn about the biceps brachii muscle anatomy? This page includes its functions, bicep exercises and more.

This upper arm muscle is commonly the biceps, for short.

This popular arm muscle is responsible for elbow flexion, which can be exemplified by the movement of "making a muscle" with you upper arm.

Check out the glossary at the end of the page if you have any trouble understanding the terminology within this guide.

• Forearm Supination. External forearm rotation that involves turning the palm upward.
• Shoulder Flexion. Lifting the upper arms upward and to the front.
• Transverse Shoulder Flexion. Moving the upper arm toward the center-line of the body and across the chest, on a horizontal plane and with the elbows pointed outward; as exemplified by a "bear hug" movement.

Anatomy

• Bicipital Aponeurosis. The flat and broad tendon connected to the biceps, on the front side of the elbow joint.
• Coracoid Process. A bony, hook-shaped structure on the front, upper region of the scapula.
• Forearm Fascia. The thick fibrous body tissue on top of the forearm muscle.
• Scapula. Shoulder blade.
• Supraglenoid Tuberosity. The small protruding bump (tubercle) on the upper, outer scapula (above the "glenoid cavity").
• Radius. The forearm bone, located on the lateral (outer) side of the elbow.
• Tubercle. A small protruding bump or knob on bones.
