Total skin thickness varies from 0.5 mm in areas such as the eyelids to more than 5 mm over the back, with most of the difference accounted for by variation in depth of the dermis. In thick skin, each of the five strata, or layers, of the epidermis described below are present, and each stratum is generally several cell layers thick Appendages of the Skin Skin appendages are formed from the epidermis but reside in the dermis. Sebaceous glands produce an oily product (sebum), usually connected by a duct into a hair follicle. Sebum keeps the skin and hair soft and contains bacteria-killing chemicals (Figure 4.2) Start studying Disorders of Skin Appendages. Learn vocabulary, terms, and more with flashcards, games, and other study tools In humans, some of the more common skin appendages are hairs (sensation, heat loss, filter for breathing, protection), arrector pilli (smooth muscles that pull hairs straight), sebaceous glands (secrete sebum onto hair follicle, which oils the hair), sweat glands (can secrete sweat with strong odour (apocrine) or with a faint odour (merocrine or eccrine)), and nails (protection)

Figure 3: Through the appendages (hair follicles, glands) As shown in Figure 3, the third pathway for diffusion of chemicals into and through the skin is skin appendages (i.e., hair follicles and glands). This pathway is usually insignificant because the surface area of the appendages is very small compared to the total skin area There are five layers of the epidermis: 2 . Stratum basale: This bottom layer, which is also known as the basal cell layer, has column-shaped basal cells that divide and push older cells toward the surface of the skin. As the cells move up through the skin, they flatten and eventually die and shed. Stratum spinosum: This layer, which is also. Made with Explain Everythin

Study Guide for Anatomy & Physiology Skin System. The skin and its appendages make up the integumentary system. The skin is an organ that performs a vital function for our body. It helps our body control its temperature, protect us from UV radiation and other environmental hazards. In addition, the sensors in our skin keep us protected by making us aware of conditions that could harm us Skin. The skin is the largest component of this system. It is an extensive sensory organ, which forms an outer, protective coat around the entire external surface of the body. In fact, it is the largest organ of the human body, covering an area of 2 square meters. It has a thickness between 1.5 and 5 mm, depending on location Appendages - such as the sebaceous glands, sweat glands and hair follicles - also exist within these layers, and they play various roles in the overall function of the skin. Structure of the skin: the three main skin layers are the epidermis, dermis and subcutis Accessory structures of the skin include the hair, nails, sweat glands and sebaceous glands. These structures embryologically originate from the epidermis and are often termed appendages; they can extend down through the dermis into the hypodermis. Hair.

A papule (figure 3-4) is a solid, elevated lesion usually 0.5 cm to 1 cm or less in diameter. Most of the lesion is above the level of the surrounding skin rather than deep within the skin. Many skin diseases start with papules--warts, psoriasis, syphilis, drug eruptions, and some phases of acne. Different types of papules are different colors The skin serves as a wall-like barrier that separates the inside of our body from the microbial enemies of the environment and provides a primary defense against infection. 1,2 The layers of the skin, like the outer wall and secondary inner walls surrounding a medieval city, not only provide protection from external enemies, but also provide niches where normal flora bacteria and fungi can.

Hair. Hair is a keratinous filament growing out of the epidermis. It is primarily made of dead, keratinized cells. Strands of hair originate in an epidermal penetration of the dermis called the hair follicle.The hair shaft is the part of the hair not anchored to the follicle, and much of this is exposed at the skin's surface. The rest of the hair, which is anchored in the follicle, lies. Anatomy & Physiology Quiz on the Skin Integumentary Structure.
