Study Notes
Main Functions of the Skin
-
Protection is a main function of the skin
-
The skin is for sensing the environment
-
The skin assists in producing vitamin D
-
The skin assists in controlling body temperature
-
The epidermis consists of mostly epithelial cells and hair shafts
-
The dermis contains hair follicles, sebaceous glands, sweat glands, sensory receptors and blood vessels
-
The subcutaneous layer is primarily fat cell and fat connective tissue
-
Sweat glands are independent of the hair follicle
-
Melanocytes produce melanin
-
Sebaceous glands are associated with hair follicles
-
Sebaceous glands produce, oily acidic secretion
-
Sebaceous glands have antibacterial properties
The Three Main Layers of the Skin
- Epidermis
- Dermis
- Subcutaneous layer
The Five Layers of the Epidermis
- Stratum corneum
- Stratum lucidum
- Stratum granulosum
- Stratum spinosum
- Stratum Basale
Types of Skin Changes with Age
- The epidermis thins and weakens as you age
- Immune cells diminish
- Milano sites decrease
- Sweat glands become less active
- Blood supply is reduced as you age
- Vitamin D production declines
- Hair thins and loses color
- The dermis weakens, causing wrinkles
- Secondary sex characteristics diminish
The Process of Body Temperature Regulation
-
The skins blood vessels dilate, bringing heat to the skin
-
Sweat glands activate
-
Sweat glands secrete moisture
-
Moisture evaporates, which reduces body temperature
-
Internal temperature stabilizes
-
Eccrine glands open directly to the skin
-
Apocrine glands are associated with hair follicles
-
When the internal temperature stabilizes, vasodilation stops and the brain discontinues the sweat signal
