Question

what is reflex arc how it's happen​

Answer 1

Reflex Arc :

The whole process of reflex action is known as reflex arc.

Procedure :

First, the receptors sense the stimulus and forward it to sensory neuron which then transfers the stimuli to the spinal cord and then to the motor neuron through relay neuron. Motor neuron transfers the processed information to the effector muscles, which act accordingly.

❤HELLO ❤

REFLEX ARC :

A reflex arc is a neural pathway that controls a reflex. In vertebrates, most sensory neurons do not pass directly into the brain, but synapse in the spinal cord. This allows for faster reflex actions to occur by activating spinal motor neurons without the delay of routing signals through the brain.

WORKING :

In a reflex arc, the sensory neuron sends a signal to the interneuron and activates it. The interneuron then relays that signal to the next neuron, a motor neuron. Motor neurons connect with interneurons in the spinal cord. They send messages from the central nervous system to the body.
