Answer 1

Somatosensation is the sense of touch. Somatosensation occurs all over the exterior of the body and at some interior locations as well. The sense of touch is detected by a variety of different types of mechanorecetpors that are embedded in the skin, mucous membranes, muscles, joints, internal organs, and cardiovascular system. In fact, what is commonly referred to as “touch”� involves more than one kind of stimulus and more than one kind of receptor. Touch in humans includes four primary tactile mechanoreceptors in the skin. You don’t need to know the specific name for each type of touch receptor (shown below), but you should be able to recognize
