CHAPTER 5 (5-1 EPIDERMIS COMPOSED OF LAYERS, (THICK AND THIN SKIN) Stratum…
CHAPTER 5
-
(THICK AND THIN SKIN) Stratum Corneum, Stratum Lucidum, Stratum granulosum, Stratum spinosum, Stratum germinativum, basement membrane
-
-
Melanin is brown, yellow-brown or black pigment produced by melanocytes
-
Sunlight can be very beneficial. When exposed to UV radiation, Spinosum and Geminativum convert a cholesterol-related steroid into Vitamin D3
-
-
Skin Cancer is the most common form of cancer. Basal Cell Carcinoma is the most common, Squamous Cell Carcinoma, and the worst is Malignant Melanoma
-
The Dermis lies beneath the Epidermis. It's two major components is a superficial papillary layer and deeper reticular layer
-
-
As it's not actually part of the integumentary system, it is important in stabilizing the position of the skin relative to underlying tissue, such as skeletal muscles or other organs, while permitting independent movement
-
Hair Papilla, Hair Root, Hair Shaft, Cuticle, Cortex, Medulla
When the arrector pili is stimulated, it pulls on the hair follicle, forcing it to stand up
-
Sebaceous glands are holocrine glans that discharge an oily lipid serection into hair follicles, or in some cases, into the skin
Apocrine Glands are glands that secrete his products into hair follicles in the armpits, around the nipples and the groin
-
Nails form on the dorsal surfaces of fingers and toes, where they protect the exposed tips and help limit their distortion when they are subjected to mechanical stress
Nail body, Nail Bed, Nail Root, Cuticle, Lunula
-
Scab. Granulation Tissue, Scar Tissue, Keloid
-
When damage extends to the epidermis and dermis, bleeding generally occurs
-
-
Skin injuries and infections become more common, The sensitivity of the immune system is reduced
Muscles become weaker, and bone strength decreases, Sensitivity to sun exposure increases, The skin becomes dry and often scaly
-
Protection from dehydration, environmental chemicals, and impacts
The Integmumentary system in perspective summarizes the interactions of the integumentary system with other body systems
