The brachial plexus is divided into five roots, three trunks, six divisions (three anterior and three posterior), three cords, and five branches….Branches.
| From | posterior cord |
|---|---|
| Nerve | radial nerve |
| Roots | C5, C6, C7, C8, T1 |
| Muscles | triceps brachii, supinator, anconeus, the extensor muscles of the forearm, and brachioradialis |
What is C5 to T1?
The nerves supporting the arm exit the spinal column high in the neck; those that support the hand and fingers exit lower in the neck. This nerve complex is composed of four cervical nerve roots (C5-C8) and the first thoracic nerve root (T1). These roots combine to form three trunks.
What is pad and dab?

What is the brachial plexus?
The brachial plexus is a network of nerves that gives rise to all the motor and sensory nerves of the upper extremity . This plexus arises from the anterior rami of spinal nerves C5-T1 that undergo several mergers and splits into trunks and divisions, until they finally give rise to their terminal branches.
