    Dermis:The second major skin region, is a strong but flexible connective tissue layer. The cell types found in the dermis are fibroblasts, macrophages, and occasional mast cells and white blood cells. Its gel-like matrix is heavily embedded with collagen, elastin, and reticular fibers. The dermis is your "hide" and is richly supplied with nerve fibers, blood vessels, and lymphatic vessels. The…

    Skin is a protective covering, helps regulate body temperature, houses sensory receptors, synthesizes chemicals, and excretes wastes. It is composed of an epidermis and a dermis separated by a basement membrane. A subcutaneous layer, not part of the skin, lies beneath the dermis. The subcutaneous layer is composed of areolar tissue and adipose tissue that helps conserve body heat. This layer contains blood vessels that supply the skin.…

    The three layers that make up healthy skin: Epidermis, Dermis and Hypodermis. Epidermis is composed of keratinized, stratified squamous epithelium. This layer provides a thick, water proof protective covering over the underlying skins. The dermis layer is composed of primarily of dense, irregular, fibrous connective tissue that is rich in collagen and elastin. The dermis contains blood vessels, nerve ending, and epidermally derived cutaneous oranges such as sweat glands, sebaceous glands and hair follicles. The last layer is Hypodermis this layer is composed primarily of loose dead skin. The fat layer provides cushioning and insulation for underlying organs.…

    Skin is the largest organ of the body, covering and protecting the entire surface of the body. The total surface area of skin is around 3000 sq inches or roughly around 19,355 sq cm depending on age, height, and body size. The skin, along with its derivatives, nails, hair, sweat glands, and sebaceous glands forms the integumentary system. Besides providing protection to the body the skin has a host of other functions to be performed like regulating body temperature, immune protection, sensations of touch, heat, cold, and pain through the sensory nerve endings, communicating with external openings of numerous other body systems like digestive system, urogenital system, and respiratory system via mucous membranes.The skin is primarily composed of three layers. The skin, which appears to be so thin, is still itself divided into epidermis, dermis, and subcutaneous layer or hypodermis. Each layer has it own function and own importance in maintaining the integrity of skin and thereby the whole body structure.…

    ANATOMY AND PHYSIOLOGY The skin is primarily composed of three layers. The skin, which appears to be so thin, is still itself divided into epider­mis, dermis, and subcutaneous layer or hy­podermis. Please refer to the figure below to understand all the three layers. Each layer has it own function and own importance in maintaining the integrity of skin and thereby the whole body structure. So lets, study each part in detail. 1. Epidermis: Epidermis is the topmost layer or rather the visible part of the skin that is composed of stratified squamous epithelial cells. This layer is com­posed of five layers of cel1s, which are arranged in two zones; the superficial horny layer and a germinal layer beneath it. The horny layer is again made up of three layers of cells. These are stratum corneum , which is the superficial layer. It has thin, flat, dead cells filled with keratin, which are constantly being cast off. Keratin is a very important constituent as it is a type of insoluble fibrous protein that helps to protect the body. This layer helps in protection against heat, chemicals, light, and microorganisms. Below this layer is stra­tum lucidum . This layer contains flat cells with no distinct outline and no nuclei. These cells contain eleidin, which is a retractile and weakly staining keratin present in the cells of the stratum lucidum of the palmar and plantar epidermis, which is a prekeratinous substance. Below this layer is stratum granulosum .…
