Skin

The epidermis is the outer (epi in Greek meaning "over" or "upon") of the two layers that make up the skin (or cutis), the inner layer being the dermis.

Sweat glands, also known as sudoriferous or sudoriparous glands, from Latin sudor, meaning "sweat", are small tubular structures of the skin that produce sweat.

Sebaceous glands are microscopic exocrine glands in the skin that secrete an oily or waxy matter, called sebum, to lubricate and waterproof the skin and hair of mammals.

Human skin color ranges in variety from the darkest brown to the lightest hues.

Melanocytes (/məˈlænəˌsaɪt, -noʊ-/ or /ˈmɛlənəˌsaɪt, -noʊ-/) are melanin-producing cells located in the bottom layer (the stratum basale) of the skin's epidermis, the middle layer of the eye (the uvea), the inner ear, meninges, bones, and heart.

Cellulite (also known as adiposis edematosa, dermopanniculosis deformans, status protrusus cutis, gynoid lipodystrophy, and orange peel syndrome) is the herniation of subcutaneous fat within fibrous connective tissue that manifests topographically as skin dimpling and nodularity, often on the pelvic region (specifically the buttocks), lower limbs, and abdomen.

The dermis or corium is a layer of skin between the epidermis (with which it makes up the cutis) and subcutaneous tissues, that primarily consists of dense irregular connective tissue and cushions the body from stress and strain.

In biology, moulting (British English), or molting (American English), also known as sloughing, shedding, or in many invertebrates, ecdysis, is the manner in which an animal routinely casts off a part of its body (often, but not always, an outer layer or covering), either at specific times of the year, or at specific points in its life cycle.

The subcutaneous tissue (from Latin subcutaneous, meaning "beneath the skin"), also called the hypodermis, hypoderm (from Greek, meaning "beneath the skin"), subcutis, or superficial fascia, is the lowermost layer of the integumentary system in vertebrates.

A birthmark is a congenital, benign irregularity on the skin which is present at birth or appears shortly after birth, usually in the first month.

The human skin is the outer covering of the body.
