Biceps Brachii Anatomy: Origin, Insertion & Action

⭐ Biceps brachii muscle anatomy ⭐
💪 Origins: Supraglenoid tubercle & coracoid process of the scapula
💪 Insertions: Radial tuberosity & bicipital aponeurosis into deep forearm fascia
💪 Action: Flexes the elbow, shoulder flexion/dynamic stability & supination of forearm
💪 Innervation: Brachial artery
💪 Artery: Musculocutaneous nerve (C5–C7)

⭐ For details on the biceps brachii playing more or a dynamic stability role in shoulder flexion rather than being a direct flexor. See the study called: 'The role of the biceps brachii in shoulder elevation' by Dennis Landin, Joseph Myers, Melissa Thompson, Ray Castle & Jared Porter. It was published in the journal of Electromyography and Kinesiology 18 (2008) 270–275.
