The bicep muscle connects from the shoulder blade (scapula) to the radius bone in the forearm.
Bicep Connections Explained
The biceps brachii, commonly known as the bicep, is a muscle located on the front of the upper arm. Understanding how it connects is key to understanding its function.
Origin of the Bicep
The bicep has two "heads" at its origin, meaning it starts in two places near the shoulder:
- Short Head: Arises from the coracoid process of the scapula (shoulder blade).
- Long Head: Arises from the supraglenoid tubercle of the scapula.
These two heads join together to form the main muscle body in the middle of the upper arm.
Insertion of the Bicep
The other end attaches to the radius, the outermost of the two bones that make up the forearm, as stated in the provided reference.
| Feature | Description |
|---|---|
| Origin | Two heads originating from the scapula (shoulder blade) |
| Insertion | Radius bone (outermost bone in the forearm) |
Function of the Bicep
By connecting the shoulder to the forearm, the bicep facilitates these movements:
- Flexion: Bending the elbow.
- Supination: Rotating the forearm so the palm faces upward.
- Shoulder Flexion: Raising the arm at the shoulder.
