skin and bones Flashcards
what are the 4 proteins in the skin?
- keratin
- collagen
- elastin
- melanin
what are the parts of the bone?
- epiphysis
- diaphysis
- cartilage
- metaphysis
what is red bone marrow?
bone marrow that contains blood stem cells that can become red blood cells, white blood cells, or platelets
what is yellow bone marrow?
bone marrow that is made mostly of fat and contains stem cells that can become cartilage, fat, or bone cells
what is spongy bone?
a soft and smooth bony structure that forms the epiphysis of long bones
has more space
filled with blood vessels
what is compact bone?
a heavy bony structure that forms the diaphysis of long bones
comminuted break
shattered/ multiple pieces of bone
greenstick break
when the bone doesn’t fully break all the way through (bent)
spiral break
a fracture from a twisting force that causes a fracture through and around the bone
oblique break
when the bone is broken at an angle
transverse break
when the bone is broke perpendicularly
compression break
when your vertebrae/spine collapses
depression break
when a portion of your skull gets crushed
keratin
helps form hair, nails, and skin
collagen
allows skin to bend (in dermis)
elastin
helps tissues to stretch (dermis
melanin
natural pigmentation (between dermis and epidermis)
bone healing stages
- hematoma
- inflammation
- soft callus
- hard callus
- remodeling
hematoma
bleeding
inflammation
swelling
soft calus
spongy bone fills in the break
hard calus
compact bone fills in the break
remodeling
new bone is formed
1st degree burn
only epidermis is damaged
burn site is red, painful, dry, and with no blisters
ex: sunburn
