MICROANATOMY

Detailed explanation-1: -Exteroceptors are the afferent nerve endings that sense stimuli originating from outside of the body, such as pain, touch, vibration, temperature, and sound. One type of exteroceptors are known as mechanoreceptors, which are receptors that respond to external mechanical stimuli such as touch, pressure, and vibration.

Detailed explanation-2: -Exteroceptors provide pressure, temperature, and touch information, and the senses of equilibrium (balance), hearing, sight, smell, and taste. Proprioceptors monitor skeletal muscle and joint movement and positioning. Somatic afferent fibers carry data from proprioceptors and exteroceptors.

Detailed explanation-3: -Cutaneous Receptors. Cutaneous receptors (exteroceptors) include mechanoreceptors, thermoreceptors, and nociceptors and subserve such modalities as touch, pressure, vibration, temperature, and nociception (pain) (Fig. 9-1).
