Biceps brachii is located in the front of the upper arm,and the whole muscle is spindle shaped.Biceps brachii has long and short head,so it is named.The brachial and biceps muscles belong to the limb muscles of the three major skeletal muscle groups.
The long and short heads meet at the middle of the humerus to form the muscle belly,and descend to the lower end of the humerus.The integrated tendon ends at the trochanter of radius and tendon of forearm.
During proximal fixation,the biceps brachii flexed and supinated the forearm at the elbow joint and the upper arm at the shoulder joint.Electromyographic observation showed that the biceps brachii had obvious EMG activity only when the palms were moved forward and the elbow was flexed.However,the potential activity of biceps brachii was very small or did not appear even when the palm was lateral to the body or elbow flexion behind the arm.This is also one of the main principles that biceps exercise basically makes the palm hold the instrument forward,which is located in the superficial layer of the forearm muscles.Function:bend shoulder,elbow and forearm supination.When the biceps brachii contracts,the elbow joint flexes;when the biceps brachii relaxes,the elbow joint extends or the forearm sags.
Strong biceps brachii will make arm bending movements more powerful,such as lifting,pulling and so on.However,biceps brachii is only a factor in strength,and how much strength it can ultimately produce is more related to the ability of other muscle groups to work together.
