The skin is made up of two major tissues layers:
epidermis and dermis
- is the most superficial layer of skin. It is a layer of epithelial tissue that rests on the dermis.
Epidermis
- is a layer of dense connective tissue.
dermis
- The subcutaneous tissue is not part of the skin.
- The subcutaneous tissue is not part of the skin.
- The subcutaneous tissue is not part of the skin.
- The subcutaneous tissue is not part of the skin.
- prevents water loss and resists abrasion.
epidermis
The epidermis, known as the cutaneous membrane is a
- keratinized stratified squamous epithelium.
The epidermis is composed of distinct layers called
strata
the most superficial stratum of the epidermis,
stratus corneum
The stratum corneum, the most superficial stratum of the epidermis, consists of dead squamous cells filled with
keratin
gives the stratum corneum its structural length.
Keratin
Cells of the deepest strata perform
mitosis
Cells of the deepest strata perform
mitosis
Excessive sloughing of stratum corneum cells from the surface of the scalp is called
dandruff
In skin subjected to friction, the number of layers in the stratum corneum greatly increases, producing a thickened area called a
callus
Over a bony prominence, the stratum corneum can thicken to form a cone-shaped structure called a
corn
- is composed of dense collagenous connective tissue containing fibroblasts, adipocytes, and macrophages.
dermis
Nerves, hair follicles, smooth muscles, glands, and lymphatic vessels extend into the
dermis
Some collagen fibers are oriented in more directions than others, forming
cleavage lines
