One of the important functions of the long head of the biceps is to stabilize the humeral head in the glenoid during powerful elbow flexion and forearm supination by the main muscle. Sacrifice of the intraarticular segment of this tendon in surgical procedures of the shoulder may produce instability and dysfunction.
What does the short head of the biceps do?
Function. The biceps is a two-joint muscle. In the shoulder joint both muscle heads partially enforce opposite movements. The long head pulls the arm away from the trunk (abduction) and turns it inwards (inward rotation) whereas the short head pulls the arm back towards the trunk (adduction).

Why does the long head of the bicep tendon affect shoulder stability?
Their data suggest that the long head of the biceps muscle contributes to anterior stability of the glenohumeral joint by increasing the shoulder’s resistance to torsional forces in the vulnerable abducted and externally rotated position.
What is the difference between long head and short head biceps?
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. The biceps brachii works across three joints, and is able to generate movements in glenohumeral, elbow and radio-ulnar joints.
Why is it called the long head of the bicep?
The biceps brachii muscle gets its name from its two origins, or immovable ends. The long head arises from the supraglenoid tubercle of the scapula, while the short head arises from the coracoid process of the scapula.
Which bicep head is responsible for the peak?
The biceps are composed of two heads: the outer (long) head and the inner (short) head. The peak is formed by the outer biceps head; therefore, if you want to bring up your biceps peak you need to build up that head.
What’s better long or short biceps?
If your ultimate goal when you start working out is to get big, muscular arms, even at rest, the long biceps is ideal. Even without tensing your muscles, your arms will indeed look full. However, if you dream of getting a “ball” effect when you contract, it will be more difficult for you than with a short biceps.

Is long head a muscle?
The long head of the Triceps brachii is one of three heads that make up the muscle. It descends between teres minor and major, dividing the wedge-shaped interval between them and the humerus into triangular and quadrangular spaces.
Does biceps stabilize shoulder?
Biceps aid in shoulder stability
The short head of the biceps originates at the top of the shoulder blades (technically called the scapula) and the long head originates just above the shoulder joint. Because of this, the biceps help the rotator cuff with shoulder stability, particularly through the shoulder area.
Where is the long head of the biceps tendon located?
The biceps muscle is in the front of your upper arm. It has two tendons that attach it to the shoulder blade bone. The long head attaches to the top of the shoulder socket (glenoid). The short head attaches to a bump on the shoulder blade called the coracoid process.
Are long muscles stronger?
A bigger muscle has a larger cross-sectional area. … Therefore, a bigger muscle – in terms of its cross-sectional area – is also a stronger muscle. This means that individuals with long muscle bellies have the potential to be quite strong.
Are longer biceps stronger?
The length of the muscles and where they attach to the bones as well as the length of the bones factor in (among other things) to the amount of force an individual can apply. It is normally referred to as a mechanical advantage or mechanical disadvantage. Neither of these make one stronger or weaker per se.
