Question

Where do sensory nerves synapse to form a reflex arc, and what is an advantage of this?

a. Spinal cord; quicker response
b. Brainstem; conscious processing
c. Autonomic ganglia; prolonged effect
d. Skeletal muscles; precise control

Answer 1

Sensory nerves synapse in the spinal cord in a reflex arc, providing a quicker response.

Step-by-step explanation:

The sensory nerves in a reflex arc synapse in the spinal cord. This allows for a quicker response because the signal does not have to travel to the brain and back. The advantage of this is that it allows for reflex actions to occur rapidly and automatically, without conscious processing in the brain.
