LAYER OF THE SKIN
EPIDERMIS
Its main function is protection, absorption of nutrients, and homeostasis. In structure, it consists of a keratinized stratified squamous epitheliumcomprising four types of cells: keratinocytes, melanocytes, Merkel cells, and Langerhans' cells
DERMIS
The dermis is the middle layer of skin, composed of dense irregular
connective tissues such as collagen with elastin arranged in a diffusely bundled and
woven pattern
HYPODERMIS
Although technically not part of the integumentary system, the hypodermis, or subcutaneous tissue, is the
layer of tissue directly underneath the dermis. It is composed mainly of connective and adipose tissue.
NAILS
A nail is a horn-like envelope covering the dorsal aspect of the terminal phalanges of
fingers and toes in humans, most non-human primates, and a few other mammals.
HAIR
The human body, apart from its glabrous skin, is covered in follicles which produce thick terminal and fine vellus hair. Most common interest in hair is focused on hair growth, hair types and hair care, but hair is also an important biomaterial primarily composed of protein, notably keratin.
