Which nerves arise from the medial cord of the brachial plexus?

The medial cord of the brachial plexus gives rise to the medial pectoral, medial brachial cutaneous, and medial antebrachial cutaneous nerves. The medial pectoral nerve innervates the pectoralis major and minor muscles, contributing to movements of the shoulder. The medial brachial cutaneous nerve supplies sensory innervation to the skin of the medial aspect of the arm, while the medial antebrachial cutaneous nerve provides sensory innervation to the skin of the medial forearm.

These nerves are particularly associated with the functions and innervation patterns of the medial cord, reflecting its contributions to both motor and sensory pathways in the upper limb. Understanding these specific nerves helps in recognizing how different parts of the brachial plexus contribute to upper limb function, which is crucial for clinical assessments and surgical procedures involving the arm.
