Epidermal Layer Of Skin Essay

The skin is divided into three different parts including the epidermis, dermis, and hypodermis. The epidermis is the outermost layer of the skin. This region of the skin has no blood cells or blood vessels running through it. All of the nutrients that the epidermis needs are received through diffusion from the dermis. The epidermis is made up of stratified squamous epithelial cells. The epidermis is made of five separate layers: the stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, and the stratum corneum. Starting at the innermost layer, the stratum basale is where mitosis of keratinocytes takes place. This layer of the epidermis also contains melanocytes which give the skin it’s pigment. As mitosis takes place in the stratum

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

Skin is the largest organ on the body. It has two layers: the thin outer layer is made up of dead skin cells that are constantly shed and replaced by new cells. The thick inner layer is made up of blood vessels, nerves, and hair follicles, which contain glands. The glands in the hair follicles produce an oily substance called sebum, which keeps the skin and hair from drying out. Daily washing will keep the skin on the face and other areas of the body clean by removing the dirt, oil, and dead cells before they can accumulate.

The outermost layer of the epidermis is known as the stratum corneum, it is water resistant and when not damaged, it protects the body from foreign substances such as bacteria, virus etc. it also ensures the protection of muscles, blood vessels, nerves and internal organs. The skin is also thicker in regions that requires more protection such as the sole of the feet and palms.

There are three primary layers of the skin: the outer layer, the epidermis and the layer beneath, the dermis and the hypodermis. The epidermis is thin, tough and waterproof while protecting the body from outside bacteria invading the body. It also contains keratinocytes which are from the basal layer which is the deepest layer of the skin. The keratinocytes reach up to the epidermis, shed and new ones form again. The dermis is the second layer of the skin and is the thickest. It is made from fibrous and elastic tissues which are made from fibrillin, elastin and collagen to create the strength and flexibility. It also contains sweat and oil glands, nerve endings, blood vessels and hair follicles. Sweat glands help the body cool off during heat

The skin is the largest organ of the body, the skin protects us from microbes and the elements, it also helps regulate body temperature, and permits the sensations of touch, heat, and cold. There are three layers of skin, this includes the epidermis, the outermost layer of skin, provides a waterproof barrier and creates our skin tone, the dermis, beneath the epidermis, contains tough connective tissue, which gives the skin flexibility and strength, hair follicles, produce the various types of hair found throughout our body, sweat glands, these produce sweat in response to stress and heat, blood vessels of the dermis are what help regulate our body temperature, and nerve ending, which sense pain, pressure and temperature and the hypodermis, the deeper internal tissue is made of fat and connective tissue, this functions as a protective shield for

The integumentary system establishes a barrier between the inside of the human body and the outside world. The purpose of this system is to provide protection from the external environment, sensation in terms of pressure, pain, and temperature, production of vitamin D after exposure to ultraviolet light from the sun, temperature regulation so as to not overheat the body, and excretion through means of sweating (Martini, Nath, & Bartholomew, 2011). The skin is able to provide the body with all of the aforementioned features because of its composition. The skin itself is made up of two layers: the epidermis and the dermis.

The skin is one of the body’s largest and multifunctional organ. Depending on body size and mass it can weigh between 7 to 22 pounds (1). The skin’s roles are: protection from microbes and harmful substances, thermoregulation and sensation receptiveness of touch, heat and cold. The skin consists of three layers: the epidermis, dermis and the hypodermis. The outermost layer of skin, the epidermis, provides a waterproof barrier and consists of melanocytes. Melanocytes produce and store the pigment melanin which creates skin tone. Underneath the epidermis is the dermis; it contains tough connective tissue, hair follicles and sweat glands. The dermis has an arrangement of nerve fibers and blood vessels. Blood vessels carry nutrients and oxygen to the cells of the dermis and the epidermis, which are avascular (2). The

Skin and its derivatives make up the integumentary system which acts as a barrier between the body and the outside world. Skin has physical, mechanical, chemical, and immunologic components which allow for body temperature regulation, protection against pathogens, cutaneous sensation, and metabolic functions. When the structural integrity of skin is compromised, its functions are impaired leading to major disability or even death.

The vertebrate integumentary system is responsible for protection and thermoregulation. The skin covers the human body and also has appendages like hair and nails that all serve to protect the body from damage. The outer layer of the skin, the epidermis serves as a water resistant barrier protecting the body from absorption and leaking while we are swimming or when it is raining. This maintains homeostasis. This means that when we submerge ourselves in water we do not fill up with water and we also do not leak water. The skin serves to protect the body against pathogens and even damaging UV radiation too. The blood vessel and nerves in the dermis serve to warn us when we are in danger by signaling pain when the sun beats too much on a body

Epidermis, dermis, and hypodermis are layers of the human skin. Epidermis is the outer layer of the human skin, dermis is in between the epidermis and the epidermis, and hypodermis is the deepest section of the skin. Epidermis unlike dermis and hypodermis acts as a protective shield for the human body and every 28 days the epidermis is renewed. Dermis is one of the major factors to your skin, it gives the skin structure and resilience to the human skin, unlike the functions of the epidermis and the hypodermis. The hypodermis is what insulates the body from cold temperatures and provides a shock absorption for the human. The all relate because they deal with the human skin but they are all different because they have different functions to better

Body temperature regulation * Vitamin D synthesis * Sensation to touch, pressure, pain and temperature * 2 main regions: * epidermis * 5 strata * corneum * top layer, cornified layer, layers of dead cells and soft keratin * lucidum * granulosum * spinosum * basale * deepest layer, contain melanocytes

Stratum Corneum this layer is the outer most layers; it is formed from numerous layers of compressed scale- like, overlapping cells. What makes up the surface of the skin is corneocytes, which are commonly called ‘dead skin cells’. Keratinocytes are found in the epidermis they travel up through the layer where they are formed into corneocytes. The stratum corneum layer protects against lights, chemicals, water loss, heat and bacteria.

It regulates the body's temperature by movements of the hairs on the surface, different paths for the

The epidermis is the outermost layer of mammalian skin and contains four types of cells: keratinocytes, which make up 90% of the cells found in this layer, Langerhans cells, melanocytes, and Merkel cells. The epidermis is a stratified squamous epithelial layer, containing keratinocytes organized in four main different strata (i.e. stratum
