Anatomy Chapter 10 Flashcards
Arrector pili muscle
Small involuntary muscles in the base of the hair follicle that cause goose flash when that appendage current contract sometimes called goosebumps and papillae
Apocrine glands
Coiled structures attached to hair follicles found in the under arm and genital areas that secrete sweat
Barrier function
Protective barrier of the dermis cranium and intracellular matrix protect the surface from the irritation and dehydration
Ceramides
Glycolipid materials that are a natural part of the skins intercellular matrix and barrier function
Collagen
Fibrous connective tissue made from protein found in the reticularlayer of the dermis give skin it’s firmness topically a large longchain molecule protein that lies on top of the skin and binds water derived from the percentage of cows and other sources
Corneocytes
Another name for stratum corny I’m so hard and waterproof protector keratinocytes is that protein cells are dried out and lack nuclei
Dermal papillae
Membranes are Bridget and groups that attached to the epidermis contains nerve endings and supplies nurse meant through capillaries to skin and follicles
Dermis
Also known as the derma corneum cutest or true skin support layer of connective tissue collagen and elastin blow the epidermis
Desmosomes
The structures that assistant holding cells together intercellular connections made of proteins
Eccrine glands
Sweat glands down all over the body with openings on the skin surface report is not attached to her follicle secretions do not produce an offensive odor
Elastin
Protein fiber found in the dermis give skin it’s elasticity and firmness
Epidermal growth factor
Stimulates cells to reproduce and heal
Epidermis
Outermost layer of the skin then protective layer with many cells mechanisms and nerve endings it is made up of five layers stratum corny him Stratham lucidum stratum granulosum Stratham Spinoza some and Stratham Germinativum
Eu melanin
As hypomelanosis dark brown to black and color people with dark colored skin mostly produce eumelanin there are two types of melanin the other type is pheomelanin
Fibroblasts
So that stimulates cells collagen and amino acids to perform proteins
Follicles
Her phone calls and sebaceous follicles are tubelike openings in the epidermis
Glycation
Caused by an elevation of blood sugar glycogen is the binding end of protein molecule to a glucose molecule resulting in the formation of damaged nonfunctioning structures known as advanced glycogen and products glycogen alters protein structures and decreased biological activity
Hair papillae
Cone shaped elevations at the base of the follicle that fit and the hairball the pipelay are filled with tissue that contains the blood vessels and sells necessary for hair growth and follicle nourishment
Hyaluronic acid
Hydrating fluids down in the skin hydrophilic agent with water binding properties
