They are from bottom to top: stratum basale stratum spinosum stratum granulosum stratum licidum stratum corneum Cells in the stratum basale are shaped like columns. As the cells divide they push the cells that have already formed into higher layers, and as they move up the layers they flatten and eventually die. There are also three specialized types of cells these are. The melanocyte This produces pigment (melanin) The Langerhans This cell is the frontline defense of the immune system in the skin The Merkel The function of this is cell s not clearly known Dermis This is the second layer of the skin, and has a thickness between.05 mm (eyelids) and3.0 mm (back). There are three types of tissue that are present throughout - not in layers.
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. Pressure sores or decubitus ulcers are the result of a constant deficiency of blood to the tissues over a bony area such as a heel which may have been in contact with a bed or a splint over an extended period of time. The surface of the skin can ulcerate which may become infected.
Dermis is mainly connective tissue, is deep to the epidermis, and is vascular * The skin contains collagen (for strength) and elastic (for stretch) fibers. * The skin is thicker on the posterior than the anterior parts of the body; thicker on lateral parts of limbs than medial parts. —Subcutaneous layer (or hypodermis) is deep to dermis, but is not part of skin. It is mainly adipose tissue B. Layers of epidermis (from deepest to superficial) 1. Stratum Basale (= base) a. has stem cells that continuously divide by mitosis
The skin provides a physical barrier to keep out foreign materials and prevent the body from drying out, while providing protection and a cushion to the body’s organs. The purpose of this research is to identify the different layers of the skin, characteristics of the skin, including its weight, surface and size. The information gathered will also explain the functions of the integumentary system, structure of the skin and the different types of skin lesions and then provide examples of diseases and disorders. The integumentary system is an important and vital function to the body protecting the surface and acting as an important means of survival. APA Style Sheet 3 The Integumentary System The integumentary system is an alternative name for the skin.
It's also found in the uterus and fallopian tubes. The movement of cilia move the ovum to the uterus. Glandular Epithelium are basically columnar epithelium with goblet cells. Some parts consist of such a large number of goblet cells that there are only a few normal epithelial cells left. They secrete substances
Unit 4222-229 Undertake agreed pressure area care (HSC2024) Karen Yardley Outcome 1 understand the anatomy and physiology of the skin in relation to pressure area care 1.1 describe the anatomy and physiology of the skin in relation to skin breakdown and the development of pressure sores. The skin is the largest organ of the body, covering and protecting the entire surface of the body. The total surface area of the skin is around 3000sq inches depending on age, height and body size. As well as the nails, hair, sweat glands and the sebaceous glands, the skin forms the integumentary system. Besides oroviding protection to the body, the skin also helps regulate body temperature, helps your immune system, provides sensations of touch, heat, cold and pain throught the sensory nerve endings.
2024 Undertake Agreed Pressure Area Care 1.1.1 The anatomy and physiology of the skin in relation to skin breakdown and the development of pressure sores. The skin is the largest organ of the body and it acts as a waterproof protector for all the internal organs and it consist of four distinct layers: The epidermis, the basement membrane zone, the dermis and the subcutaneous layer. The epidermis which is the outer layer and is a protective multilayered self renewing structure which varies in thickness depending on which part of the body it covers under this the dermis, this is a layer of connective tissue which provides the skins elasticity and strength, it also contains sensory nerve endings, blood and lymph vessels, sebaceous and sweat glands. Under this layer is the subcutaneous fat layer; this separates the skin from the underlying bone and muscle with rich blood supply it also serves as an insulator and energy store. Pressure ulcers develop when a large amount of pressure is applied to an area of skin over a short period of time.
The body soon loses color as the blood pools in the lowermost portions of the body. The bacteria in the stomach then begin to break down the body itself while insects, maggots, and scavengers break down the skin. Over several days the brain begins to liquefy and drain out through the mouth, nose, and ears. Blisters soon form on the skin, which eventually peels off in large sheets. Researchers at the Body Farm have discovered that when the skin is soaked in warm water, it can restore its flexibility and can be used for fingerprint identification.
The skin has two layers, the epidermis and the dermis, although not part of the skin, the hypodermis lies beneath the dermis. When the skin is about to be damaged it shows signs of redness and warmth on the area. Skin gives protection against biological invasion, physical damage and ultra violet radiation. It also provides us sensation for touch, heat and pain. Thermoregulation is supported through sweating and regulation of blood flow through the skin and synthesis of Vitamin D occurs.
The small intestine breaks down most of the protein, fat, and carbohydrates we eat. The small intestine also works with the liver, pancreas, and gallbladder for digestion. The stomach is 1 foot and takes 2 to 6 hours to digest, once food is swallowed it enters the stomach then begins the task of digestion. Once food is in the stomach digestive juices partially digest the food and breaks it down to smaller pieces. Once the stomach completes the role of digestion it
