In this image, the dermis rests below the dark epidermis. It has two layers: the first is the papillary layers (hill layer) which consists mainly of areolar connective tissue. the second layer is the reticular layer that si dominated by dense fibrous connective tissue, the irregular form. See below
In sensitive regions of the body, such as the finger tips, Meissner's corpuscles are present. these have very small receptor fields, allow for a discrete sense of touch.

Hair follicle oblique section
Hair follicle with sebaceous gland. Eccrine glands far right.
Typically located by a hair follicle is the arrector pili muscle that causes goose bumps when cold. this contraction helps to warm the skin.

Specialized glands of the armpits and groin, the apocirne glands, are represented by these large glandular regions. At 10x, it is difficult to see that they too are made of stratified cuboidal epithelium. They are not true apocrine glands as mno cell fragments are secreted, in spite of their name.

The hypodermis is the region ebwlo the dermis. it contains adipose tissue, but many appendages reside with iit, even though it is not considered a part of the skin proper. We see a sporty eccrine gland imbedded in this hypodermis, complete with duct.
The Pacinian corpuscle is usually found in the hypodermis. It is for deep pressure and vibration. The cells that surround the free dendrite end in the center are Schwann cells.
