AP PSYCHOLOGY

Detailed explanation-1: -Proprioceptors mediate deep somatic sensation from receptors beneath the skin, in muscles and joints, and in the inner ear. Proprioception includes the senses of movement, vibration, position, and equilibrium. Interoceptors mediate sensation from the viscera as well as visceral pain and pressure or distention.

Detailed explanation-2: -Interoceptors respond to stimuli inside the body, including from blood vessels and internal viscera. They are also called visceroceptors, monitoring chemical changes, temperature, and tissue stretching. They may cause discomfort, pain, hunger, or thirst, but are usually not perceived.

Detailed explanation-3: -Such receptors are referred to as exteroceptors because they deal with the environment. The skin has three types of these exteroceptors spread throughout the epidermis and dermis. These receptors are cutaneous mechanoreceptors, nociceptors, and thermoreceptors.

Detailed explanation-4: -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-5: -Interoceptors are located within the viscera of the body and are sensitive to changes in the internal environment.
