|
Keratinocytes (def.) |
Keratin-making cells that live and die in the epidermis |
|
Cells in the top layer of skin (the epidermis)... |
Create skin color |
|
Melanin (def) |
Pigment made by melanocytes (melanin-making cells) that determine skin color, Protects from ultraviolet rays |
|
Melanin colors ... |
Black, brown, yellow, and red |
|
Since hair is an offshoot of the epidermis... |
Human hair is also comes in the same colors as melanin |
|
Pink skin is actually skin with very low melanin.... |
The blood vessels showing through are what make the pink color |
|
Epidermis is like a callus... |
There has no blood supply and no nerves |
|
Dermis (def.) |
2nd layer of skin a matrix of collagen and elastin fibers |
|
Collagen is strong, but not very stretchy... |
Elastin is stretchy, but not very strong |
|
Sensory nerves in the dermis register heat, cold, pressure, pain, and touch... |
Too much heat, cold or pressure will turn into pain |
|
Dermis contains sweat glands and oil glands .... |
Sweat cools you and get ride of toxins Oild keeps your skin lubricated |
|
Acid mantle (def) |
Sweat and oil mix to create a lubricant that repels and kills bacteria |
|
Fibroblasts (def) |
Cells that have a "blast" making fibers. Spin fibers to close wounds |
|
Scar tissue (def) |
Fibroblasts that form densely in large and deep wounds so that blood vessels can't get through |
|
Subcutaneous layers (def) |
A.K.A hypodermis Layer of rounds cells under the dermis and is compromised of fat cells. Fat cells can only expand and shrink |
|
Fat keeps in body heat |
Fat is always being used and added. Supports the organ |
|
Subcutaneous layer provides a pathway for blood and nerves Anchors our skin to the underlying tissues. |
Fat is not responsible for "flab" underused muscle is |
|
Bones why? |
Because muscles attach to bone |
|
206 bones in the skeletal system |
Pairs (2 arm bones, 2 thigh bones) Sets (24 vertebrae, 14 finger bones) 35 other bones |
|
Functions of bones |
Provide structure for movement (bones are what muscles and connective tissues attach to), Protect organs, Store minerals (ready to deliver calcium into the bloodstream), House marry which makes blood cells |
|
What is Bone? |
highly responsive to use, Respond to amount of stress placed on them, Bones cells have the ability to sense how much stress has been placed upon them |
|
Osteoblasts (def) |
Bone construction is done by this. Convert dissolved minerals in the blood into mineralized crystal. |
|
Osteoclasts (def) |
Demolition in bone, Dissolve bony crystal, releasing minerals back into the bloodstream |
|
