Explanation:
Detailed explanation-1: -For instance, if you picked up a hot coal, the signal from the sensory neurons in your fingertips would travel to interneurons in your spinal cord.
Detailed explanation-2: -If you touch a hot stove, sensory receptors in your fingertip sense the dangerous heat and convert this stimulus into an electrical signal. This signal leaves your fingertip via nerve cells called sensory neurons.
Detailed explanation-3: -Receptor in the skin detects a stimulus (the change in temperature). Sensory neuron sends electrical impulses to a relay neuron, which is located in the spinal cord of the CNS. Relay neurons connect sensory neurons to motor neurons. Motor neuron sends electrical impulses to an effector.
