Friedman- 3 Integumentary System - Sheet1 Flashcards
classification of body membranes
epithelial membrane + connective membrane
epithelial membrane
-cutaneous membrane: skin -mucous membrane -serous membrane
connective membrane
synovial membrane (is the soft tissue found between the articular capsule (joint capsule) and the joint cavity of synovial joints.)
Integumentary system
-skin -hair -nails
skin
-sweat glands -oil glands -excretory system -vitamin D synthesis
Integumentary system functions
-protect w/ bacteria, chemical, mechanical, thermal -maintain temperature w/ sweat and flush (blushing)
two layers of skin
epidermis + dermis
epidermis
epithelial cells
dermis
connective tissue: -hair follicle -sensory nerves -oil glands -sweat glands -muscle
subcutaneous tissue
deep to the dermis: fat tissue act as shock absorber & insulation
EPIDERMIS cell types
melanocytes & keratinocytes
melanocytes
-Melanin(protein) -effect of sun -role in protection of keratinocytes
keratinocytes
-keratin(protein) -protective role (needs to be protected from UV)
Skin color
melanin, carotene, & oxygen rich hemoglobin
appendages of skin
- sebaceous gland (oil) 2. sweat glands
