N 224 Lecture Notes - Lecture 5: Stratum Corneum, Eccrine Sweat Gland, Apocrine
Document Summary
Sensory nerve fibers and autonomic motor nerves. Sweat glands eccrine glands and apocrine glands. Hemoglobin: red-purple tone underlying the vascular bed. Loss of dermal thickness thinning of skin and skin becomes more transparent, means an increase in susceptibility to damage. Flattening of papillae dryness and pruritus. Sweat gland atrophy and decrease in vascularity decreased sweating and ability to regulate body heat thermoregulation disturbed. Collagen and elastin loss increase in wrinkling and laxity of skin loose skin. Growths such as skin tags and warts, rough patches (keratosis), and other blemishes are more common in older people. Loss of subcutaneous fat loos of fatty pads protecting bones and resulting in skin breakdown and resulting in pain. Decline in fibroblast proliferation increased time for wound healing. Decreased melanocytes increased need for protection from the sun. History changes in the skin color change in moles/birth marks. Nail changes rash; lesions/ changes in lesion appearance feeling changes (pain, pressure, itch, tingling)
