capitulum and trochlea
the specific parts of the chondyle
unilateral
one limb
bilateral
both limbs
ipsilateral
one side of body affected
contralateral
opposite side
anatomical position
non-weight bearing, feet drooped, thumbs out
attention (fundamental position)
head forward, palms at sides, feet at 90 degrees
skin
largest organ of the body
21 ft2
what is the square foot of skin in the average adult?
7%
percentage of body weight the skin takes up
30,000-40,000
how many skin cells flake off every minute?
keeps bad stuff out; protects from heat/cold; utilizes/stores water, salt, fat, and blood; sensation info (pain, pressure, temp, etc); fights diseases, germs, and cancers; excretes waste; makes vitamins
skin’s 7 jobs
tzaaraath
term for lots of sweeping diseases of skin and clothes
leprosy
this disease is contagious, caused by bacteria, more likely to effect people with weak immune systems, treated with antibodies/anti-biotics
epidermis, dermis, subcutaneous fat
skin’s 3 main layers
1st degree- epidermis, 2nd degree-dermis, 3rd degree-fat, 4th degree-muscle
degrees of burns
free nerve ending
light sensitive touch
Pacinian nerve
deep, give pressure sensations
capillary actions
little blood vessels
sweat glands
excrete waste and cooling and excess mineral experse
sebacous glands
create wax material (makes hair oily)
arrector pilli
muscles on each hair
melanocytes, keratinocytes, langerhan cells
cells of epidermis
melanocyte
this skin cell has pigment which is melanin in the epidermis but in the new cell area - it is deep
freckles
patches of melanin
albinism
no melanin (different levels)
tanning
this activity stimulates melanocytes which causes more melanin
melanoma
skin cancer difficult to treat
keratinocytes
more than 85% of epidermal cells
keratinocytes
this skin cell produces a protein called keratin
keratin
a protein that protects skin from UVA, UVB, and waterproofs skin
keratinocytes
this skin cell is deep in the epidermis sometimes called basal cells, with new skin, these cells travel closer to the surface = squamous cells
skin cancer
basal cell carcinoma and squamous cell carcinoma (treatable)
langerhan cells
this skin cell is technically part of the immune system, they fight foreign invaders and cancerous cells of the skin, made in bones, travel to skin’s epidermal layers
70
how many instances of hermatidrosis are recorded in history?
temp regulating, excretion of body waste, fights some bacteria growth, nerve response (emotional, psychological)
some reasons why we sweat!
sebaceous glands
gland that produces oil called “sebum”
sudoriferous glands
this type of gland includes eccrine glands (exercise sweat) and apocrine glands (sexual sweat)
ceruminous glands
glands that produce ear wax
