Final answer:
Lesions of the median nerve can result in Pope's blessing or OK sign. These hand gestures are seen in patients with median nerve palsy due to compression or injury to the nerve.
Step-by-step explanation:
Lesions of the median nerve can result in Pope's blessing or OK sign.
Pope's blessing, also known as hand of benediction, is a hand gesture where the fingertips and thumb touch while the other fingers are extended. This gesture is seen in patients with medial nerve palsy due to compression or injury to the median nerve.
The OK sign, where the thumb and index finger form a circle, is also affected by median nerve lesions. Damage to the nerve can cause weakness or paralysis of the muscles involved in the gesture.
