Dermis

are not blood vessels in this layer. On the epidermis are epidermal ridges that allow it to lock with the dermis. The cells within the epidermis are keratinocytes that produce keratin and are the most numerous; melanocytes that are in the deepest layer of epidermis and produce melanin; tactile cells that are associated with tactile sensation and connect to nerve endings in the deepest layer of the epidermis; and epidermal dendritic cells that ingest bacteria and foreign debris and epidermal cancer cells. The layers of the epidermis are the stratum basal which is the deepest layer of the epidermis and is a single layer of columnar/cuboidal keratinocytes resting on basement membrane; the stratum spinosum which contains epidermal dendritic cells and is below the above the stratum basal; stratum granulosum is above the stratum spinosum and contains keratinocytes which undergo keratinization here; stratum lucidum is above the stratum granulosum and is mostly seen in thick skin and contains flattened, anucleate keratinocytes; and the stratum corneum is the layer above the stratum lucidum made up of 20-30 layers of anucleate keratinocytes and is constantly shedded.…

The Integumentary System Objective: Identify the skin structures on a model and name the layers of the skin. Also observe the degree of burns on a model. Materials: One skin structure 3-dimensional model One degrees of burn model Procedure: The model was observed for identification of the skin layers and its related structures. The second model was observed for the degrees of burn. Results: The layers of the human skin and the degrees of burn. Observation: The main purpose of…

1. The three major layers that make up healthy skin are the epidermis, dermis, and the hypodermis. The epidermis is a keratinized stratified squamous epithelium that resists abrasion and reduces water loss. It have four cell types and five layers. The dermis made of strong, flexible dense irregular connective tissue. It contains the blood vessels, nerve fibers and lymphatic vessels. The sweat glands and the hair follicles live in the dermis layer. The hypodermis is deep to the skin. It is made…

Integumentary System: Anatomy and Physiology of the Skin The skin covers the entire body surface, making up most of a humans body weight. Skin tissue provides the human body with protection from mechanical, chemical, thermal damage, and bacteria. Along with this, the skin provides insulation while regulating heat and cushioning for tissues and organs. This body system also helps with the prevention of water loss, but also allows excretion of things such as urea, salts, and water. The skin has…

Definition Cellulitis is an inflammatory condition of the dermis and subcutaneous tissue usually found obstructing a wound, ulcer or dermatosis [10]. Cellulitis is a common bacterial infection. It may appear as a swollen, red area of the skin that will feel hot and tender to touch. Cellulitis can spread to other parts of the body however it is not contagious and cannot spread from person to person. The lower leg of the body is most commonly affected, although cellulitis can occur anywhere…

1. The three major layers that make up healthy skin are the epidermis, dermis, and the subcutaneous tissue (hypodermis). The epidermis is a keratinized stratified squamous epithelium that resists abrasion and reduces water loss. It consists of four distinct cell types and five layers. The dermis, the second major skin region containing strong, flexible connective tissue. It is composed of dense irregular connective tissue. Also, the dermis contains the blood vessels, nerve fibers and lymphatic…

systems that work together to help us function as one organism. The systems we learned about in class are the integumentary system, digestive system, excretory system, skeleton system,, and muscular systems. We dissected a fetal pig to get a better understanding of it and how it relates to us. We named the pig the great name of Wilbur since he was a male. He was a full term, or ready to be born, since he measured out to be over 30 centimeters. Then after we identified every we needed on Wilbur…

Skin Portion: Yhara Barba The skin of a human is an elastic covering that acts a protects the body . The skin has many functions that greatly benefit the body. The functions are Protection, sence of touch, and it controls temperfature. Protection: The skin helps to keep bacteria and dangerous stuff out of our body, like germs and dirt that can cause infection. Adding on it helps retain water. Sence of Touch: The skin is hoem of one of our five senses: touch. Within our skin thre are thousands…

The skin is organized in two parts: the epidermis and the dermis. The epidermis is the thin outer covering of the skin. It serves as a permanent protective barrier that helps to keep out everything from water to microorganisms. Additionally, it has the task to renew itself if cut or damaged in anyway. Furthermore, the epidermis also help to produce a water resistant protein called keratin, which helps the growth of hair and fingernails. The dermis is the inner layer of the skin that is mostly…

damage from stage I to stage IV. Pressure ulcers can reduce the overall quality of life for the patient due to pain and increased hospital stay. Many patients will be on pain medications, and many will require debridement. Debridement is the removal of devitalized tissue and foreign matter from the wound. Descriptions and Stages A stage I wound is fairly mild. It has a persistent area of red skin that is intact, not broken. It could be painful. It could be warm and spongy or firm to the touch.…
