Functions of Integumentary System
Acts as a barrier to protect body; Retain body fluids; Protect against disease; Eliminate waste; Regulate Temp
3 Major layers of Integumentary System
Hair; Skin; Nails
3 Epidermal Cells
Mechanoreceptors; Melanocytes; Langerhans Cells
Function of Mechanoreceptores
Receptor cells that are sensitive to touch and pressure
Function of Melanocytes
Produce protein; Protect nucleus from radiation
Function of Langerhans cells
Immune cells that surveil the epidermis
Layers of Epidermis
Stratum Corneum; Stratum Lucidum (Only in hands and feet); Stratum Granulosum; Stratum Spinosum; Stratum Basale
Function of Stratum Corneum
Protects inner layers of skin and waterproofs
Function of Stratum Lucidum
Lowers effects of friction on the skin
Function of Stratum Granulosum
help to form a waterproof barrier that functions to prevent fluid loss from the body; Cells contain granules that make keratin
Function of Stratum Spinosum
Phagocytosis
Function of Stratum Basale
Makes brown pigment melanin
Papillary Layer
superficail layer, forms fingerprints
Reticular Layer
Deep, Think Layer
Major Skin Pigments
Melanin; Carotene; Hemoglobin
Color Produced from Melanin
Yellow to Tan, Reddish Brown to Black
Color produced from carotene
Yellow/Orange
Color produced from hemoglobin
Pink Hue
Exocrine Glands
Apocrin; Mammory; Sudoriferous; Sebaceous; Ceruminous
Function of Apocrin Glands
Scent glands in axilla, anogenital
Function of Mammary glands
produce milk
Function of Sudoriferous glands
Secrete perspiration to cool skin
Function of Sebaceous Glands
Secretes oil to lubricate | Secretes into hair folicle
Function of Ceruminous Glands
Produces Wax in the ear
4 Components of hair
Shaft; Root; Follicle; Arrector Pili
Function of the hair shaft
Provides strength, color and texture of hair
Function of Hair Root
Cells in bulbs carry on mitosis to produce new hair cells
Function of Hair Follicle
Dialated at base to form bulb
Function of Arrector Pili
When muscle contracts it pulls skin down | Causes goosebumps
3 Major types of Cancer
Basal cell carcinoma… Most Common; Squamous cell carcinoma; Malignant Melanoma… Lease Common
Where do you normally get squamous cell carcinoma
Upper lip, Scalp, Ears
Different Degree of burns
1st; 2nd; 3rd
1st Degree burn
Epidermal damage only | Red and painful
2nd Degree burn
Epidermal and dermis damage | Blisters
3rd Degree burn
Through (maybe deeper) dermis | Muscle and bone may also be damaged
Rule of 9's
Allows the portion of a body burned to be quickly quantified; Helps guide a treatment plan; Decides a transfer to a burn unit
