The lateral cord is a division of the brachial plexus. Cervical spinal nerves C5, C6, and C7 contribute to it.
The lateral cord gives rise to the following nerves:
- The lateral pectoral nerve to the pectoralis major muscle
- The musculocutaneous nerve which innervates the biceps muscle
- The median nerve, partly. The other part comes from the medial cord.
