AP PSYCHOLOGY

Detailed explanation-1: -The sense of touch is a mix of four distinct skin senses-pressure, warmth, cold, and pain. Only pressure has identifiable receptors. All other skin sensations are variations of pressure, warmth, cold and pain.

Detailed explanation-2: -Of the four distinct skin senses, the only one that has definable receptors is: pressure. The sense of touch includes the four basic sensations of: pressure, pain, warmth, and cold.

Detailed explanation-3: -Pacinian receptors detect pressure and vibration by being compressed, stimulating their internal dendrites. There are fewer Pacinian corpuscles and Ruffini endings in skin than there are Merkel’s disks and Meissner’s corpuscles.

Detailed explanation-4: -Mechanoreceptors: These receptors perceive sensations such as pressure, vibrations, and texture. There are four known types of mechanoreceptors whose only function is to perceive indentions and vibrations of the skin: Merkel’s disks, Meissner’s corpuscles, Ruffini’s corpuscles, and Pacinian corpuscles.

Detailed explanation-5: -Cutaneous receptors Four receptor structures of the glabrous skin provide this information: Merkel discs, Meissner corpuscles, Pacinian corpuscles, and Ruffini endings.
