![]() ![]() Epidermal cells are replenished in the basal layer and are pushed outward by newly forming layers. These layers are the basal (deepest), spinous, granular, clear, and horny/cornified (superficial) layers. The epidermis comprises five distinct layers. The dermis provides most of the thickness of the skin. The three primary layers of the skin are the epidermis, the dermis or corium, and the hypodermis or subcutis (also called the panniculus). ![]() This organ may also play a limited role in the excretion of some substances from the body ( Table 11-1). The skin plays a role in immunologic defense through the actions of Langerhans (dendritic or antigen-presenting) cells and keratinocytes, produces vitamin D 3 from precursors in the skin, and acts as a reservoir for electrolytes and other substances. It senses heat, cold, pain, touch, pressure, and other sensations like pruritus and helps to regulate body temperature through mechanisms related to cutaneous blood flow, sweating, and the haircoat. It provides a barrier against the outside world by preventing entry of pathogenic microorganisms and by protecting against physical and chemical insults. It is made up of three layers ( Figure 11-1) and serves multiple functions. The skin is a part of the integumentary system and constitutes the largest organ in the body. Client education is essential when skin disease is treated because clients must understand the purpose of medications and how they should be properly used. Technicians play a vital role by obtaining a complete history, knowing how to perform the diagnostic procedures used in a dermatologic workup, and providing client education. Veterinarians use various diagnostic procedures (e.g., skin scrapings, allergy testing, and dermatophyte tests) to determine the cause of skin disease. Patients are often presented for examination of a skin disease when in reality they have an underlying systemic illness. Each of these products may be used to treat a full spectrum of dermatologic problems from parasites to pyoderma. As a veterinary technician, this is one area in which your expertise will be used because clients will ask many questions about shampoos, dips, conditioners, soaks, lotions, creams, ointments, sprays, powders, and topical products designed to have activity against fleas, ticks, and mosquitoes. From ectoparasitic problems to allergies, veterinarians are continually combating companion animal skin problems.
