Body Membranes in Epithelial
Mucous
Serous
Function of Mucous membrane
Locations
line body cavities that open to the outside
Respiratory
Digestive Tract
Reproduction
Function of Serous membrane
Locations
Line cavities that dont open directly to the outside, reduces friction between organs
Lines body walls
Lines Organs
Body Membranes in Connective
Synovial
Meninges
Function of Synovial membrane
Locations
Lines cavities of freely movable joints
Elbow
Shoulder
Knee
Function of Meninges Membrane
Location
Provides protection
Covering Brain and Spinal cord
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
