GENERAL HISTOLOGY

Detailed explanation-1: -Sensory neurons get information about what’s going on inside and outside of the body and bring that information into the CNS so it can be processed. For instance, if you picked up a hot coal, sensory neurons with endings in your fingertips would convey the information to your CNS that it was really hot.

Detailed explanation-2: -Nociceptors are sensory receptors that detect signals from damaged tissue or the threat of damage and indirectly also respond to chemicals released from the damaged tissue. Nociceptors are free (bare) nerve endings found in the skin (Figure 6.2), muscle, joints, bone and viscera.

Detailed explanation-3: -Specifically, if you accidentally touch a hot iron, the quick withdrawal is the result of nerve impulses carried by the b. efferent neurons. Moreover, these are neurons in charge of sending neural impulses from the central nervous system towards the correspondent muscles, so the person can generate movement.
