Question: 1 / 425

What does the digital nerve do?

Controls the movement of the wrist

The digital nerve is a branch of the median and ulnar nerve in the hand that primarily controls the movement of the fingers and thumb. Option A is the correct answer because it specifically mentions the function of the digital nerve. Option B is incorrect because it refers to the sensory impulses of the fingers, which is the function of the digital nerve's branches (palmar digital nerves). Option C is incorrect because the regulation of the body's temperature is mainly controlled by the autonomic nervous system. Option D is incorrect because transmitting visual information to the brain is the function of the optic nerve, not the digital nerve.
