Question
Chapter 15, Problem 6RQ
Summary Introduction
To identify:
The six types of tactile receptors located in the skin and also describe their sensitivities.
Introduction:
The closely related sensations of touch, pressure, and vibration are provided by tactile receptors. The pressure sensations indicate the degree of mechanical distortion and touch sensations provide information about shape or texture.

Describe the three types of touch and pressure receptors.
Given that touch receptors are not uniformly distributed on the body surface, name two sites where the highest density of receptors are found.

A greater skin surface area always results in a lower two-point threshold because there is physically more room in which to house sensory receptors. With a low two-point threshold, there is a greater density of sensory receptors to allow for more precise location of the sensation by the somatosensory cortex. O A low threshold suggests a decreased sensation in that area, meaning a wide receptive field on that area of skin.arrow_forwardState the location and general function of each type ofcutaneous receptor.arrow_forward
