- Long Head
- Short Head
- Coracoid Process of scapula
- Distal biceps tendon
- Courses laterally and deep
- Inserts on Radial tuberosity of proximal Radius on the ulnar aspect
- Bicipital Aponeurosis
- Also termed lacertus fibrosus
- Extends medially to insert on the fascia of the forearm
- Distal biceps tendon anatomy
- There is no distal tenosynovial sheath, only a paratenon
- Classical description: single flat tendon which rotates 90° externally as it moves from anterior to posterior and medial to lateral
- More recent: there are distinct short-head and long-head components contributing to a bifurcated tendon
- Bicipitoradial Bursa
- Located between the distal biceps tendon anteriorly and the radial tuberosity posteriorly
- Lies along the medial cortex of the radius, partially envelops the distal biceps tendon
- Occasionally it ensheaths the tendon
- Role: reduce friction between distal biceps tendon, proximal radius during pronation and supination
- Enlargement can impair flexion/ extension of elbow, compress neurovascular structures
- May compress superficial or deep branches of the radial nerve causing sensory or motor symptoms, respectively
- Interosseous Bursa
- Lies medial to the biceps tendon
- May compress median nerve when enlarged
- Compressive symptoms can worsen with pronation caused by increase tension within the bursa
- Flexion of the elbow
- Flexion and abduction of the shoulder
- Stabilization of the glenohumeral joint when the upper extremity is abducted and externally rotated 
- Anterior Humeral Circumflex Artery
- Brachial Artery
- Musculocutaneous Nerve (C5–C7)
