Chap 4 Flashcards
4 types of tissues
epithelial
connective
muscular
nerve
epithelial
protect from drying out, bacteria, injury tightly packed cells, readily divide nutrients from connective tissue avascular (w/o blood vessels) free surface + basement membrane
Epithelial layers
simple (single)
stratified (multilayer)
Epithelial shapes
squamous (square)
cuboidal (cubed)
columnar (column, tall, skinny)
pseudostratified (falsely stratified/stacked)
transitional (ability to change, stretchy)
connective tissue
enclosing and separating connecting tissues together supporting and moving storing cushioning and insulating protecting
cells separated by…
a matrix of organic ground substance fiber
Connective tissue classification
adipose (stores fat) loose (fibers run randomly) dense (fibers run uniformly) cartilage bone
cartilage
hyaline (not very flexible, hard, covers ends of long bones)
fibro- (hard, a little flexible)
elastic (flexible, holds shape)
bone
spongy (has air pockets, sturdy but light)
compact (solid, densely packed)
muscle tissues
skeletal
smooth
cardiac
skeletal
striated
voluntary (control with your mind)
multiple nuclei
smooth
no striations
own nucleus
involuntary
cardiac
striations
single nucleus
involuntary
nervous tissue
neuron carries electrical impulse
neurological
glands
group of cells that produce a substance
single cell or multicellular structure that secrets substances into the blood, cavity, or the surface
