Pin On Health Anatomical terms of muscle. in human anatomy, the biceps brachii ( ˈbaɪsɛps ˈbræki.aɪ ), commonly known as the biceps, is a two headed muscle that lies on the upper arm between the shoulder and the elbow. both heads arise on the scapula and join to form a single muscle belly which is attached to the upper forearm. The biceps brachii muscle is one of the chief muscles of the arm . the origin at the scapula and the insertion into the radius of the biceps brachii means it can act on both the shoulder joint and the elbow joint, which is why this muscle participates in a few movements of the arm. it derives its name from its two heads which merge in one.
Medical Students Nursing Students Nursing School Biceps Brachii There are multiple actions across the elbow and shoulder joints with which the bb is involved, all in conjunction with other muscles. it is one of three muscles that flex the elbow and it does this work along with the brachialis and brachioradialis [ 1, 4, 5 ]. it is also one of three that flex the shoulder (with coracobrachialis and anterior. Biceps brachii and brachialis (ag) 108.7 kb. examination. muscle function: flexes the elbow joint. the short head assists with shoulder adduction. the long head may assist with abduction if the humerus is laterally rotated. origin fixed: flexes the elbow joint by moving the forearm toward the humerus. The biceps brachii (bb), commonly know as the biceps, is a large, thick muscle on the ventral portion of the upper arm. the muscle is composed of a short head and a long head. the long head is located on the lateral side of the biceps brachii while the short head is located on the medial side [1]. the biceps brachii works across three joints. The biceps brachii is a biarticular muscle attached to two joints – the elbow and shoulder. in the elbow joint. the biceps helps in the supination of the forearm, which means rotating it outwards so the hand faces upward. the primary functioning of the muscle happens when the arm is in this position. it assists in bending or flexing the forearm.

Summary. biceps brachii. origin. short head: tip of coracoid process of scapula; long head: supraglenoid tubercle of scapula. insertion. tuberosity of radius and fascia of forearm via a bicipital aponeurosis. action. supinates and flexes forearm. 1.1 anatomy. the biceps brachii muscle has two heads: the long head which originates from the supraglenoid tubercle and the short head which originates from the coracoid process. both heads merge to form a distal muscle belly and the main portion inserts to the radial tuberosity of the radius and the rest to the deep fascia of the forearm.
