Skin Anatomy and Physiology

The subcutis is not a layer of the skin, but rather the layer of fat and connective tissue that lies beneath the skin.

The epidermis is the outermost layer of the skin and its primary function is to protect the body from the environment.

Adipocytes are fat cells and are not found in the skin.

Melanin is a pigment that gives skin its color and protects it from the harmful effects of ultraviolet radiation.

Excretion is not a function of the dermis.

The hypodermis is the deepest layer of the skin and its primary function is to insulate the body.

Sebaceous glands are oil glands and are not sweat glands.

The primary function of sweat glands is to help regulate body temperature by producing sweat.

Reproduction is not a function of the skin.

The skin is the largest organ of the human body, covering a surface area of approximately 2 square meters.

Humans have three layers of skin: the epidermis, dermis, and hypodermis.

The outermost layer of the skin is called the epidermis.

The middle layer of the skin is called the dermis.

The innermost layer of the skin is called the hypodermis.

The function of the epidermis is to protect the body from the environment.

The function of the dermis is to provide support and structure to the skin.

The function of the hypodermis is to insulate the body and store energy.
