Wrist drop is characteristically caused by injury to the:
सही उत्तर: ख) Radial nerve
The radial nerve supplies the extensors of the wrist and fingers, so its injury (e.g. in mid-shaft humerus fracture at the spiral groove) produces wrist drop. Ulnar nerve injury causes claw hand instead.

Foot drop most commonly results from injury to the:
सही उत्तर: घ) Common peroneal (fibular) nerve
The common peroneal nerve winds around the neck of the fibula, where it is easily injured, paralysing the dorsiflexors and causing foot drop. Tibial nerve injury instead weakens plantar flexion.
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
Winging of the scapula results from injury to the:
सही उत्तर: क) Long thoracic nerve
The long thoracic nerve (C5–C7) supplies serratus anterior, which holds the scapula against the chest wall; its paralysis causes winging. The thoracodorsal nerve supplies latissimus dorsi and does not cause winging.
