epidermis
dermis hypodermis |
epidermis - = epithelim
dermin = = connective tissues hypoderjis = adipose + connective tissue |
|
|
appendages
|
accessory components (hair follicle, sweat glands)
|
|
|
name p. 149 epidermis
|
Keratinized stratified squamous epithelium:
|
|
|
4 principle cells types in epidermis
|
From base up: Stratum basale (deepest layer) , stratusm corneum (most superficial). 2nd = stratum granulosum 3rd up = stratum lucidum
|
|
|
most bottom layer
|
stratum basale
|
|
|
2nd bottom layer
|
stratum spinosum
|
|
|
3rd from bottom
|
stratum granulosm - (stains well) w/dark granules
|
|
|
4 th from bottom
|
stratum corneum - no nuclei - bec it's just keratin
|
|
|
5 th from bottom
|
stratum lucidum (not always seen)
|
|
|
stratum meaning in Latin
|
stratum = layer
|
|
|
Keratinocytes' function
|
a glycoprotein - produces keratin
|
|
|
Melanocyte
|
produces melatonin, esp under sun, skin produces melanina -protects a layer & damaging the basal layer, to protect cells from UV rays
|
|
|
where 're melanoyte found?
|
dark stratum basale layer
|
|
|
All non-melanocytes cells are called
|
keratinocytes
|
|
|
what's dermis made up?
|
>80 % dense irregular
loose connective tissues |
|
|
in chicken
|
epi & dermis easy to move, hypo
|
|
|
where's the fat
|
mostly hypo layer
|
|
|
mountaints (& valleys) form?
|
papilla = elevation
= valley tissues that form = papillary layer |
|
|
lower region (of papillary)
|
reticular region = dense irregular tissue
|
|
|
below dermis you have ____ layer
|
subcutaneous layer, aka superfacial fascia, aka hypodermis
= a lot of adipose tissue, a little loose connective |
|
|
is there any blood vessels in epithelium?
|
No!
|
|
|
Imagine you're cutting the arm, what layers do you find?
|
Epidermis, dermis, hypo (adipose = subQ = superfasical fascia, deep fascia, connective tissue
|
|
|
renship between superficial fascia & muscle?
|
superficial fascial of superficial to muscle
|
|
|
deep fascia is the muscle
|
deep fascia is superficial to the muscle
|
|
|
LUMEN part 13, slide 1 lable all parts
|
dermal papilla, stratum grnulosum, stratum corneu, stratum basale, (from bottom up)
|
|
|
name this tissue type
|
dense irregular
|
|
|
what's down here?
|
adipose (hypodermis layer_
|
|
|
Slide 2
|
stratum corneum, dense irregular (= tissues type), skin layer type ( = dermis) thsi is a seat gland
|
|
|
slide 3: name row of cells
|
stratum basale, stratum spinosum, granulosm, all the stuff aboe, corneum
|
|
|
slide 3: name the white stuff
|
loose connective tissues (body is dynamic )
|
|
|
slide 4
|
name white: corneum, granulosm spinosum
|
|
|
slide 7
|
dermal papill, stratum baasale, melanocytes ( = dark cells, keratonocytes (all cells toward surface), stratum corneum ( = top layer)
|
|
|
slide 8
|
stratum corneu, granuled layer in layer = granulosum
|
|
|
slide 11

an encapsulated nerve
|
|
|
sebaceous glands
|
oil glands for hair, oil goes into hair follicle. on test, the gland will have a duct going into hair follicle
|
|
|
sweat gland
|
more watery, saline, has enzymes, body, protective substances, produces mostly watery, salty, other substances
|
|
|
eccrine
|
true sweat gland, found in forehead, palms, feet, releases water for temperature regulation
|
|
|
apocrine
|
unique to armpits, secretion is more milky substance, where microorganism reside (like your armpit smells), in the axilary region, in anal genital area, more emotioanlly related
|
|
|
gives you goose bumps
|
arrector pilli muscle
|
|
|
3 encapsulated sensory receptors
|
Meissner's copuscle (sens light touch)
Pacinian corpuscle (sense deep pressure) Free nerve edings (sense temp + pain) |
|
