Answer 1

Answer:

Five basic element of reflex arc are receptor, sensory neuron, integration center, effector and motor neuron.

Explanation:

Reflex arc may be defined as the neural pathway of reflex action. Reflex may be defined as a response against a particular stimulus that returns the body to homeostasis.

Five basic elements of reflex arc are as follows:

Receptor: Receptor is present at the end of a sensory neuron and they respond against a stimuli.

Sensory neuron: The neuron carries nerve impulse from the receptor to the  brain or spinal cord.

Integration center: This center consists of more than one synapse in brain or spinal cord.

Motor neuron: This neuron conducts nerve impulse from the central nervous system to the effector organ.

Effector: Effector respond against a nerve impulse and may contract or secrete a product depending upon the effect.
