Skin

The integumentary system comprises the skin and its appendages acting to protect the body from various kinds of damage, such as loss of water or damages from outside.
In mammals, the skin is an organ of the integumentary system made up of multiple layers of ectodermal tissue, and guards the underlying muscles, bones, ligaments and internal organs.

Feather

feathersplumagebarbule
The integumentary system includes hair, scales, feathers, hooves, and nails. Many chromatophores are also stored in this layer, as are the bases of integumental structures such as hair, feathers, and glands.
They are considered the most complex integumentary structures found in vertebrates and a premier example of a complex evolutionary novelty.

Human skin

skinoily skinskin aging
The human skin (integument) is composed of at least two major layers of tissue: the epidermis and dermis.
The human skin is the outer covering of the body and is the largest organ of the integumentary system.

Scale (anatomy)

The integumentary system includes hair, scales, feathers, hooves, and nails.
Scales are generally classified as part of an organism's integumentary system.

Adipose tissue

The deepest layer, the hypodermis, is primarily made up of adipose tissue.
In the integumentary system, which includes the skin, it accumulates in the deepest level, the subcutaneous layer, providing insulation from heat and cold.

Epidermis

Vitamin D

In most land vertebrates with significant exposure to sunlight, the integumentary system also provides for vitamin D synthesis.

Dermis

Epithelium

The epidermis is the top layer of skin made up of epithelial cells. In structure, it consists of a keratinized stratified squamous epithelium; four types of cells: keratinocytes, melanocytes, Merkel cells, and Langerhans cells.

Keratin

The major cell of the epidermis is the keratinocyte, which produces keratin, a fibrous protein that aids in skin protection.

Nail (anatomy)

Lunula (anatomy)

The lunula is the crescent-shape area at the base of the nail, lighter in color as it mixes with the matrix cells.

Loose connective tissue

The dermis is the middle layer of skin, composed of dense irregular connective tissue and areolar connective tissue such as a collagen with elastin arranged in a diffusely bundled and woven pattern.
