Reflex arc:
- Reflex is a neurological mechanism or pathway that controls reflex.
- Reflex or reflex action refers to the instantaneous response to the stimuli without thinking.
- In reflex arc as soon as the spinal cord receives a signal the response will be seen even before the brain gets the single.
- Whenever we touch any hot object the immediate response seen is an example of a reflex action.
Types of neurons involved in a reflex arc:
- Reflex arc involves only three types of neurons sensory, motor, and relay neurons.
- A sensory neuron receives the signal and passes it to the relay neuron.
- Relay neuron is present in the spinal cord and acts as a connection between sensory and motor neurons.
- The motor neuron carries the signal to the target organ or site.
