Question

explain the process of reflex arc​

Answer 1

Answer:

The reflex arc is activated to create a rapid response in order to maintain safety. It is an innate, automatic response to a dangerous stimulus. It involves 3 neurones. ... The relay neurone will deliver this response to the motor neurone it synapses with, causing a signal to be sent to an effector, generally a muscle.

Answer 2

Sensory neuron sends electrical impulses to a relay neuron, which is located in the spinal cord of the CNS. Relay neurons connect sensory neurons to motor neurons. Motor neuron sends electrical impulses to an effector. Effector produces a response (muscle contracts to move hand away).
