Studying the integumentary system in the lab you will likely learn the parts of the skin on several models and look at sections of skin under a microscope.  The above YouTube playlist and practice images may be of help.

Here are some labeled images of skin models and histology (click on images for a larger version).

Cutaneous receptors on the smaller skin model (click image for larger version)

By the way…  All of the receptors found in skin are part of what are called general senses—  sense of pressure, touch, stretch, pain, vibration, and temperature change.  These general senses are pretty much everywhere in the body while the special senses are only found in the head (sight, hearing, equilibrium, taste, and smell).

03.17 skin 450X hair follicle and sebaceous gland and eccrine sweat gland

Above is an image of thin skin (100 X magnification)  In this image we can see three hair follicles, part of a sebaceous gland, an eccrine sweat gland, and part of a sweat gland duct.
