Q. How the process of reflex action occurs in when our hand touches a hot plate?

#Need explanation!

Answer 1

the sensory nerves at that site sends nerve impulse to the brain. and the brain responds to That stimulus and send another impulse to the motor nerves in our hand.. So we draw our hand back.

Answer 2

Heya sis,

When we touch a hot object, thermo receptors present in our skin receive the stimulus and changes it into nerve impulses which are carries to spinal cord by sensory neurons. Thereby spinal cord instructs the effectors  through motor neuron then our muscle contradicts and we remove our hand
Pathway:-
Stimulus------------>Receptors----------> Sensory neuron------> spinal cord-----------> motor neurons------> effectors------Response
