Understanding Brachial Plexus Anatomy
The brachial plexus is a complex nerve network. It goes from the spinal cord in the neck to the armpit. It’s key for moving muscles and sending sensory info to the shoulder, arm, and hand. Knowing about it helps us see how injuries can affect moving the arm.
Components of the Brachial Plexus
The brachial plexus has roots, trunks, divisions, cords, and branches. Roots come from the cervical spinal nerves (C5-C8) and the first thoracic nerve (T1). These roots join to make three trunks: upper, middle, and lower.
- Roots: C5, C6, C7, C8, T1
- Trunks: Upper (C5-C6), Middle (C7), Lower (C8-T1)
- Divisions: Each trunk splits into an anterior and a posterior division.
- Cords: Lateral, medial, and posterior cords are formed by the divisions.
- Branches: The cords give rise to several major nerves, including the musculocutaneous, axillary, radial, median, and ulnar nerves.
Function of the Lower Trunk
The lower trunk of the brachial plexus is key for moving the arm. It helps with motor and sensory functions of the forearm and hand. If it gets hurt, moving and using the arm can be hard.
The lower trunk’s branches include the ulnar and part of the median nerve. These nerves are important for fine hand movements and feeling in the hand. The ulnar nerve helps with fine finger movements, and the median nerve affects how we grip things.
| Component | Function |
|---|---|
| Roots (C5-T1) | Initial formation of the brachial plexus structure. |
| Upper Trunk | Controls shoulder and elbow movements. |
| Middle Trunk | Primarily contributes to forearm flexion. |
| Lower Trunk | Vital for hand and finger movements, impacting overall arm mobility. |
Common Causes of Lower Trunk Brachial Plexus Injury
