Question

Name, in order, the five main components of a reflex arc. Briefly explain what each component is or does.

Answer 1

Answer:

The five parts of reflex arc are sense organs (receptor) followed by sensory neuron, then the inter neuron,  motor neuron and lastly by the muscles/body organs.

Explanation:

The five parts of reflex arc are -

a) The first part is the receptor which comprises of sense organ whose function is to sense the impulse and pass the perceived information to the sensory neuron.  

b) The sensory neuron then carry the information from sense organs to the central nervous system (CNS) for processing.

c) The inter neurons carry the information from CNS to the motor neuron

d) After receiving processed  information/ action potential  from inter neuron it is sent to the other parts of the body and away from the CNS .

e) Lastly, the muscles/body organs which receive information from the motor neuron,  enact as directed by the CNS as a response to the impulse received.
