Lab: tissues Flashcards
Epithelial function
covers surface and lines hollow structures
epithelial location
skin, bladder is lined with it, makes up swear, oil, and secretary glands
epithelial is classified by
arrangement and shape
1 layer
simple
multi layer
stratified
squamous
thin and flat
cuboidal
cube shape
columnar
column shape
transitional epithelium
always changing its shape found in bladder because of pressure in bladder
stratified function
protection/barrier, example=skin
simple function
filtration, secretion, absorption
connective tissue
most abundant tissue in the body
connective function
connect things together, support/protect, has immune function
examples of connective
small intestine, liver, bone, blood,collagen, elastic fiber, reticular
hyaline function
found where 2 surfaces will glide against each other
2 types of muscle
skeletal and cardiac
skeletal
attaches to bone/voluntary
simple squamous
fried egg
simple cuboidal
not a perfect square ever
simple columnar
long columns with a nucleus at the end of the rectangle
stratified squamous
no shape really, just squeezed.
nervous tissue function
generate electrical signal
nervous tissue description
has a neuron in it
areolar is
loose, connective
areolar description
has strength, looks like hair. but not as strong as white fibrous
adipose is
loose connective
adipose description
looks like cracked dessert
adipose function
storage of fat
bone description
beehive
blood function
transport oxygen
blood description
little red circles
white fibrous is
dense connective
white fibrous description
all goes in one direction, tight. makes up tendons and ligaments. collagen fibers
hyaline description
cells clumped together, often in pairs
elastic is
cartilage
elastic
looks like huge bubbles
muscle tissue
skeletal and cardiac
skeletal description
belly of a snake
cardiac description
has intercalated disc
