2. BRACHIAL PLEXUS
• Networking of the spinal nerves, formed by
ventral of cervical spinal nerves and thoracic
spinal nerves
• Brachial plexus is responsible for sensory and
motor innervation of the entire upper limb

4. 5 main nerves arise
from brachial plexus
1. Axillary nerve
2. Musculocutaneous nerve
3. Radial nerve
4. Median nerve
5. Ulnar nerve

6. AXILLARY NERVE
• Arise from the posterior cord of brachial plexus at
the level of axilla
• Lies posterior to the axillary artery and anterior
to the subscapularis muscle
• Then axillary nerve will divide into anterior
branch (upper branch) and posterior branch
(lower branch)

9. Median nerve
• Nerve that passes down the full length of the arm into
the hand
• Median nerve is next to the brachial artery
• Median nerve is most often injured with a wound to
the axilla
• Responsible for controlling the forearm and muscles

11. Musculocutaneous nerve
Is a nerve that formed by splitting of the brachial
plexus
Opposite to the lower border of pectoralis minor
Arise from root C5, C6, and C7

12. Musculocutaneous nerve

13. Radial nerve
• Arise from the posterior cord of brachial
plexus
• The radial nerve enter the arm behind the
axillary artery and then travel posteriorly on
the medial side of the arm
• Run down underside of the arm which also
control the movement of triceps and also for
extending the wrist and fingers.

15. ULNAR NERVE
• Arise from the medial cord of the brachial
plexus
• Runs near the ulna bone
• Damage to the ulnar nerve may due to long
term pressure on the elbow. For example claw
hand deformities.

16. Ulnar nerve
