Question

Draw neat and labelled diagram of refiex action and explain
it's function in details.=​

Answer 1

Required Answer :-

The reflex arc describes the pathway in which the nerve impulse is carried and the response is generated and shown by the effector organ.

The reflex arc typically consists of five components:

1. The receptor is present in the receptor organ.
2. The sensory neuron conducts the nerve impulses towards the central nervous system (CNS). The CNS is comprised of the brain and the spinal cord.
3. The information is transferred from one neuron to other.
4. A motor neuron conducts the response nerve from the CNS to the effector organ.
5. The effector organ shows response by contracting or secreting a product. The instant movement performed by the individual in response to the stimulus is known as a reflex action.

Functions :-

Reflex arc is a neural pathway that controls the reflex action. It is a pathway followed by nerves which carry sensory from the receptor to spinal chord and then carry the response of the spinal chord to the effector organs during a reflex action.

Nerve cells have neurotransmitter storage vesicles going only in one direction and the receptors are in only one place. Therefore, the nerve impulses cannot move in opposite directions.
