PATHOLOGY

Detailed explanation-1: -When high temperature is sensed in the skin, a reflexive withdrawal is initiated by the muscles of the arm. Sensory neurons are activated by a stimulus, which is sent to the central nervous system, and a motor response is sent out to the skeletal muscles that control this movement.

Detailed explanation-2: -For example, if you step on something sharp, the nerves in your foot send a pain signal up your spinal cord to your brain. When your brain recognizes the danger, it sends another signal down your spinal cord to the nerves in your leg and foot muscles, telling them to pull away from the object.

Detailed explanation-3: -Afferent neurons are neurons whose axons travel towards (or bringing information to) a central point, while an efferent neuron is a cell that sends an axon (or carries information) away from a central point.
