Skin is the largest organ in the body and covers the body's entire external surface. It is made up of three layers, the epidermis, dermis, and the hypodermis, all three of which vary significantly in their anatomy and function. The skin's structure is made up of an intricate network which serves as the body's initial barrier against pathogens, UV. • Hairless skin of the palms of the hands and soles of the feet is thick skin, referring to thickness of epidermis. • The thickest skin based on the thickness of the dermis is on the uppe The epidermis, the outermost layer of skin, provides a waterproof barrier and contributes to skin tone. The dermis, found beneath the epidermis, contains connective tissue, hair follicles, blood vessels, lymphatic vessels, and sweat glands. The deeper subcutaneous tissue (hypodermis) is made of fat and connective tissue The Integumentary System: The Epidermis By Janet Rae-Dupree, Pat DuPree Skin — together with hair, nails, and glands — composes the integumentary system. The epidermis, which contains no blood vessels, is made up of layers of closely packed epithelial cells The epidermis consists of an outer layer of cells that form a stratified epithelium, and a deeper layer of undifferentiated cells, called basal germinative layer, adjacent to an acellular basal lamina or basement membrane, that separates the epidermis from the dermis

The human skin (integument) is composed of at least two major layers of tissue: the epidermis and dermis. (The hypodermis or subcutaneous layer is not part of the skin [citation needed].) The epidermis is the outermost layer, providing the initial barrier to the external environment. It is separated from the dermis by the basement membrane The largest organ of your body is your skin (known as integument in the world of clinical anatomy). It includes the outer covering that protects your inside parts from the elements and from viruses and bacteria. The skin is also necessary for heat regulation, sensation, and making vitamin D. The skin can be a good indicator of health The epidermis is the outermost layer of the three layers of skin. Its thickness depends on where it is located on the body. For example, it's thinnest on the eyelids (half a millimeter). It's thickest on the palms of the hands and soles of the feet (1.5 millimeters) The skin : anatomy - The anatomy of the integumentary system. General physiology - Questions on human physiology.

Human Epidermis Diagram Human skin diagram human skin

Epidermis. The epidermis is the most superficial layer of the skin, and is largely formed by layers of keratinocytes undergoing terminal maturation. This involves increased keratin production and migration toward the external surface, a process termed cornification. There are also several non-keratinocyte cells that inhabit the epidermis Skin consists of two layers: (1) the epidermis, which is classified as keratinized stratified squamous epithelium; and (2) the dermis (corium), which is composed of connective tissue (Plate 135). Beneath the dermis is the hypodermis or subcutaneous superficial fascia, which may be composed primarily of fatty connective tissue, a stored energy reserve Integument, cutis or simply skin is the outermost covering of the body. It is the first organ of the body that is visible when we encounter an animal and helps us in identification of the type of organism. Although simple in appearance, skin is a complex organ that performs many functions in the body and hence is sometimes aptly called The Jack of all trades, which means it carries out. The epidermis - the outermost tissue itself consisting of three separate layers of cells. The dermis or corium - the middle tissue. The hypodermis - the innermost layer or tissue. The fowl's skin is divided into a number of separate areas where the skin has been modified to some extent to be able to carry out special functions. These.

This article, which forms part of the life sciences series, examines the anatomy and physiology of skin, also termed the integumentary system. Skin is composed of two main layers, the epidermis and dermis. The structure of the epidermis and dermis are described and their functions are discussed. Acc Epidermis, in zoology, protective outermost portion of the skin. There are two layers of epidermis, the living basal layer, which is next to the dermis, and the external stratum corneum, or horny layer, which is composed of dead, keratin-filled cells that have migrated outward from the basal layer The epidermis is composed of the outermost layers of the skin. It forms a protective barrier over the body's surface, responsible for keeping water in the body and preventing pathogens from entering, and is a stratified squamous epithelium, composed of proliferating basal and differentiated suprabasal keratinocytes.. Keratinocytes are the major cells, constituting 95% of the epidermis, while.
