Heat and Cold
Thermal damage
Sunlight
Ultraviolet
Bacteria
Microorganism
Contains a water-resisting glycolipids and keratin (prevents drying out)
Desiccation
Activate sweat glands and allow blood to flush into the skin capillary
beds (heat radiate from skin surface)
Body Heat loss
Not allowing blood to flush into skin capillary beds
Heat Retention
Through PERSPIRATION
Excrete UREA /URIC - Through PERSPIRATION
Acid
Modified molecules in skin converts to Vitamin D by sunlight
(Epidermal cells produce cholecalciferol (vitamin D3
)
Synthesizes Vitamin D
A pigment that ranges in color from yellow to
brown to black
Melanin
- Specialized spider shaped cells
- Produces Melanin
- Found in the STRATUM BASALE
Melanocytes
important in alerting and
activating immune system cell
(bacteria/viral invasion)
Epidermal dendritic cells
- Seen in Epidermal – Dermal
Junction - Associated with SENSORY NERVE
ending
Merkel cells
Serves as touch
receptors
Merkel Disc
help us to
make firm grip whenever we
hold something by our hands.
Ridges of our palm
- STRONG and STRETCHY envelop that
binds the body together - Rich in blood supply
Dermis
a network of arteries along the reticular layer
Cutaneous plexus:
capillary network from small arteries in papillary layer
Papillary plexus:
15-30 days
It takes how many days for
a cell to move from
stratum germinosum
to stratum corneum”
protect the sensitive tips of
fingers and toe
Support the tips of our fingers and
toes, protect them from injury,
Pick up small objects
Enhance fine motor movements
Nails
Adipose Tissue
Deposits of subcutaneous fat:
Have distribution pattern determined by
hormones
Reduced by cosmetic liposuction
Lies below the integument
Stabilizes the skin
Allows separate movement
Hypodermis
Blood flow
Gland secretions
Sensory receptors
Nerve fibers skin control
