GENERAL HISTOLOGY

Detailed explanation-1: -The somatosensory system allows the human body to experience pressure, texture, temperature, and pain, and to perceive the position and movement of the body’s muscles and joints.

Detailed explanation-2: -The skin is covered with sensory receptors that respond to touch, temperature, and pain stimuli. The pain receptors (nociceptors) are also sensitive to chemical agents released in their vicinity.

Detailed explanation-3: -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.
