Question #02b6d
1 Answer
See below.
Explanation:
A reflex- Is the quick action you make when subjected to a stimulus.
Reflex Arc
When we touch a hot bowl (here), the receptors present in our skin send an electrical impulse through neurons; via the sensory neuron it reaches the spinal cord and thus the message is sent to the brain.
The brain receives the signal while the reflex is being carried out. When reaching the relay neuron, it is transmitted through the motor neuron back to the effector that is the muscle.
The activation of the spinal motor neurons allows for a faster reaction time, hence the muscle moves to take the hand away from the hot object before instructions come back from the brain. This process together is called as reflex arc.
Thus we sense the heat and take our hand out of a body.
