Physiology Flashcards
Arrector pili muscle
Small involuntary muscle in the base of hair follicles that causes goosebumps
Apocrine glands
Coiled structure attached to hair follicles in underarms or genital area
Barrier function
Protective Barrier of the epidermis
Ceramics
Gulp lipid material that are a natural part of the skins matrix and barrier function
Collagen
Connective tissue made from protein found in the dermis skin it’s firmness
Corneocytes
Another name for stratum Cornium cellHardened waterproof protective
Dermal papillae
Membranes the ridges and grooves attached to the epidermis contain nerve endings and supplies nursishmeng
Dermis
Also known as derma support layer of connective tissue collagen and elastin below the epidermis
Desmosomes
Structure that assist in holding cells together
Eccrine glands
Sweat glands found all over the body with openings on the skins surface through pores
Elastin
Protein fibers on the dermis give skin it’s elasticity and firmness
Epidermal growth factor
Stimulates cells to reproduce and heal
Epidermis
Outer most layer of the skin a protective layer with many cells and nerve endings made up of 5 layers
Eumelanin
Melanin that is dark brown or black in color
Fibroblast
Cells that stimulate cells collagen and amino acids that form proteins
Follicles
Hair follicles and sebaceous follicles are tube like openings in the epidermis
Glycation
Caused by elevation in blood sugar
Hair papillae
Cone shaped elevations at the base of the follicule to sit into the hair bulb
Hyaluronic acid
Hydrating fluids found in the skin
Hydrolipidic
Oil water balance that protects the skin surface
Intercellular matrix
Lipid substance between corneum cells that protects the cell from waterless
Karatin
Protein of cells that is also the principal component of the skin hair and nails
Keratinocytes
Epidermal cells composed of Karatin lipids and other proteins
Langerhans immune cells
Guard cells of the immune system that sense invaders such as bacteria. And then process these antigens for removal
Leukocytes
White blood cells that have enzymes to digest and kill bacteria and parasites
Lymph vessels
Okay did in the dermis they supply nourishment with in the skin and remove waist
Melanin
Tiny grains of pigment produced by melanocytes that determines hair and skin color
Melanocytes
Cells that produce skin pigment granules in the basal layer
Melansomes
Pigment carrying granules that produce melanin a complex protein
Papillary layer
Top layer of dermis next to the epidermis
Pheimelanin
A type of melanin that is red and yellow in color people would light colored skin mostly produce this
Pores
Tubelike opening for sweat glands on the epidermis
Reticular layer
Deepest layer of the dermis that’s the place is in and nutrients contains fat cells and blood vessels hair follicles sweat glands and lymph vessels and sebaceous glands
Rosacea
Condition appears primarily on the cheeks and nose and is characterized by redness
Sebaceous glands
Oil glands
Sebum
Oil
Sebaceous glands
Also know as oil glands
Stratum Corneum
Outermost layer of epidermis
Stratum germinativum
Active layer produces new skin cells and responsible for growth
Stratum granulosum
Composed of cells filled with keratin
Statrum lucidum
Clear layer is epidermis thick skin on palms of hands and feet
Stratum spumiosum
Intercellular connections made of proteins
Subcutaneous layer
Adipose tissue fat tissue beaneath dermis
Subcutis tissue
Adipose tissue below dermis contains fat used as energy
Sudoriderous glands
Sweat glands
T cells
Identify molecules that have foreign peptides
Telangietasia
Capillaries that have been damaged and are no larger
Transepidermal water
Water loss caused by evaporation to
Tyrosinase
Enzyme that stimulates melanocytes
UVA radiation
Aging Rays
uvb radiation
Burning Rays
