Question

Which component of the reflex arc carries the impulse into the dorsal root of the spinal nerve and into the spinal cord?

A) Sensory Receptor
B) Sensory Neuron
C) Interneuron
D) Motor Neuron

Answer 1

The sensory neuron carries the impulse into the dorsal root of the spinal nerve and into the spinal cord.

Step-by-step explanation:

The component of the reflex arc that carries the impulse into the dorsal root of the spinal nerve and into the spinal cord is the Sensory Neuron. Sensory neurons are responsible for carrying nerve impulses from sensory receptors in tissues and organs to the central nervous system. They change physical stimuli such as touch, light, and sound into nerve impulses. In the reflex arc, the sensory neurons transmit the sensory information to the spinal cord, where it is processed and a response is generated.
