Question

The dorsal root of spinal nerve mediates the movement of motor impulses to go out of the spinal cord.

• A. True
• B. False

Answer 1

The correct option is B

False

Spinal nerves are connected to the spinal cord by either dorsal root or ventral root. The spinal cord transmits impulses from different parts of the body to the brain and vice versa. Sensory impulses reach the spinal cord through the dorsal root and motor impulses go out of the spinal cord through the ventral root.
