MHS 277-278 Thin Skin

Thin Skin

Section of thin skin stained with hematoxylin & eosin. Thin skin covers most of the body except for the palms of the hands and soles of the feet.

Epidermis - stratified squamous kerantinized epithelium divided into four layers:

Stratum Basalis
Stratum Spinosum
Stratum Granulosum
Stratum Corneum

Dermis - dense irregular connective tissue that supports the epidermis

Papillary Layer - connective tissue firmly attached to the epidermis by the basement membrane

Elastic fibers (unstained) - helps keep the skin smooth with few wrinkles

Reticular Layer - less organized connective tissue that supports the papillary and the epidermis

Thin Skin

Thin skin stained with Verhoeff stain to demonstrate the presence of elastic fibers.

Epidermis (brown) - non-specific staining
Dermis - dense irregular connective tissue that supports the epidermis

Papillary Layer - connective tissue firmly attached to the epidermis by the basement membrane

Elastic fibers (black) - vertical fibers that help keep the skin smooth with few wrinckles

Reticular Layer - less organized connective tissue that supports the papillary and the epidermis

Wrinckles are most noticeable on the hands, arms, and face. These are the parts of the body more likely to have not been covered with clothing over a lifetime. Exposure to UV rays slowly damages these elastic fibers allowing the formation of wrinckles.
