MEDICAL PHYSIOLOGY

Detailed explanation-1: -General visceral afferent interoceptors monitor events within the body, including bladder distention and pH changes in the blood. Special visceral afferent receptors are those of taste and smell (olfaction). Special somatic afferent receptors are concerned with vision, audition, and balance or equilibrium.

Detailed explanation-2: -Deep pressure and vibration is transduced by lamellated (Pacinian) corpuscles, which are receptors with encapsulated endings found deep in the dermis, or subcutaneous tissue. Light touch is transduced by the encapsulated endings known as tactile (Meissner’s) corpuscles.

Detailed explanation-3: -Interoceptors (visceroceptors) respond to stimuli occurring in the body from visceral organs and blood vessels. These receptors are the sensory neurons associated with the autonomic nervous system. Proprioceptors respond to stimuli occurring in skeletal muscles, tendons, ligaments, and joints.

Detailed explanation-4: -Located deeper in the dermis and along joints, tendons, and muscles are Ruffini’s corpuscles and Pacinian corpuscles. These mechanoreceptors can feel sensations such as vibrations traveling down bones and tendons, rotational movement of limbs, and the stretching of skin.
