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 |
