Peripheral nerve function extends beyond motor and cutaneous roles. The posterior interosseous nerve terminates in the dorsal wrist capsule and contributes innervation to the TFCC. The dorsal sensory branch of the ulnar nerve and the medial antebrachial cutaneous nerve add further afferent input. These represent part of a broader network of ligamentous and capsular afferents essential to wrist proprioception. Their continuous feedback allows the central nervous system to refine motor output, sta

Anatomy Students: Students tend to overlook Superficial Peroneal nerve. Superficial peroneal nerve is commonly asked indirectly. So, on the question stem, you might see a question that a patient can dorsiflex the foot but the cutaneous innervation of the lateral compartment of the leg and the dorsum of the foot is lost. The Deep Peroneal nerve is the motor branch involving dorsiflexion, while Superficial peroneal is responsible for the cutaneous innervation of the lateral compartment of the leg
