Chapter 10 Flashcards
Arrector pili muscle
Goosebump muscle
Barrier function
Acid mantle, protects skin
Ceramides
Natural part of skins intercellular matrix
Collagen
Fibrous connective tissue
Corneocytes
Dead skin cells
Dermal papillae
Attach to epidermis. Contains nerve endings and capillaries
Dermis
Support layer of connective tissue
Desmosomes
Assist in holding cells together. Made of proteins
Eccrine glands
Sweat glands found all over body
Elastin
Protein fiber found in dermis
Epidermal growth factor
Stimulates cells to reproduce
Epidermis
Outermost layer of skin. Has 5 layers
Eumelanin
Black melanin
Fibroblasts
Stimulating cells
Follicles
Pores
Glycation
Caused by elevation in blood sugar
Hair papillae
Supplies hair with nutrients
Hyaluronic acid
Holds 1000 times its weight in moisture
Hydrolipidic
Oil-water balance that protects skin
Intercellular matrix
Between skin cells to hold moisture
Keratin
Protein
Keratinocytes
Keratin cell
Langerhans immune cells
Guard cells
Leukocytes
White blood cells
Lymph vessels
Supplies skin with nourishment and removes waste
Melanin
Pigment
Melanocytes
Melanin making cells
Melanosomes
Melanin protein
Papillary layer
Top layer of dermis next to epidermis
Pheomelanin
Red or yellow in color. Mostly in light colored skin
Pores
Tube like openings
Reticular layer
Deeper layer of the dermis supplies skins w/O and nutrients
Rosacea
Condition where face looks flushed all the time
Sebaceous glands
Oil glands
Sebum
Oil in skin and hair that protects it
Stratum corneum
Horny layer
Stratum germinativum
Basal layer. Mitosis takes place here.
Stratum granulosum
Granual layer. Replaces she’s cells from corneum
Stratum lucidum
Clear layer of epidermis. Thicker on palms of hands and bottom of feet
Stratum spinosum
Spiny layer. Just above basal layer. Contains Desmosomes
Subcutaneous layer
Hypodermis. Fat
Subcutis glands
Adipose tissue. Fatty tissue below dermis that creates contour
Sudoriferous glands
Sweat glands.
T-cells
Identify molecules that have foreign peptides and also help regulate immune response
Telangiectasia
Capillaries popping out
Transepidermal water loss
TEWL. water loss caused by evaporation on skin’s surface
Tyrosinase
Enzyme that stimulates melanocytes and thus produces melanin
UVA rays
Aging Rays. The deepest and the weakest
UVB rays
Burning Rays.
Apocrine glands
Coiled structures attached to hair follicles found in the underarm and genital areas, secrete sweat
