Let's take the example of touching something hot:
there's sensory nerves in all our body, including our hands and fingers. When a finger touches something hot. a nerve impulse will be born due to the stimulus and will be transmitted from the sensory nerves in the finger to the CNS (central nervous system)
The CNS will integrate the information, then transmit nerve impulses through the motor nerves which goes to the muscles of the finger (which are skeletal muscles) to order them to contract, to avoid the contact between the finger and the hot thing. (the same map for the blinking eye)
