Tag: Long head biceps

The human biceps brachii is a bi-articular muscle, meaning it crosses both the shoulder and elbow joints. This makes understanding what are the parts of the shoulder bicep crucial for grasping its function in movement and stability, as well as the causes of common injuries.

An estimated 90-95% of proximal biceps tendon ruptures involve the long head, highlighting a key distinction between the two tendons of the biceps muscle. This significant difference in injury susceptibility and function begs the question: What is the difference between the long head and the short head tendon?
