|
what are the 4 types of tissues?
|
epithelial
connective muscular nervous |
|
|
epithelial
|
barrier/lining or a gland
tightly packed, numerous #'s of individual cells no direct bloodvessels |
|
|
connective
|
varied in what they do
bones-hard blood-liquid,plasma (^both have matrix's) fat tissue |
|
|
muscular
|
all have special characteristic-they contract
|
|
|
what are the three types of muscular tissue?
|
skeletal
smooth cardiac |
|
|
nervous
|
detects changes inside and outside the body and repsonds by generating action potentials (nerve impulses0 that help maintainence of homeostasis
movement stimulation generates electricity |
|
|
epithelium
|
consists of cells arranged in continuous sheets, in either single or multiple layers
|
|
|
epithelial cells
|
numerous, tightly packed, arranged in sheets or layers or a few individual cells (glands)
|
|
|
basal surface area
|
has basement membrane
|
|
|
basement membrane
|
extracellular layer between epithelium and connective tissue consisting of a basal lamina and reticular lamina protien, serves as a barrier between epithelial from anything ajoining it
|
|
|
O2 in cell
|
simple diffusion
|
|
|
C6H12O6 in cell
|
facilitated diffusion
|
|
|
epithelial division
|
mitosis occurs easily
|
|
|
lumen
|
hollow portion of tubes
|
|
|
epithelial lining
|
apical side closer to lumen
basal side further from lumen |
|
|
single layer
|
simple
|
|
|
multilayered
|
stratified
|
|
|
squamous cell
|
flat
|
|
|
cuboidal cell
|
cube shaped
|
|
|
columnar cell
|
rectangular
|
|
|
pseudostratified
|
looks stratified but is simple
|
|
|
transitional
|
change shape then go back to original shape
|
|
|
Example of transitional
|
urinary bladder-
full--cuboidal-->squamous after urination back to cuboidal |
|
|
ciliated
|
cilia present
|
|
|
nonciliated
|
no cilia present
|
|
|
What are the two types of glands in human body?
|
exocrine
endocrine |
|
|
exocrine
|
make and process into ducts
secretions delivered to surface of location |
|
|
Examples of exocrine
|
sweat, saliva, bile, tears, musous, oil, earwax, milk, vaginal fluid
|
|
|
endocrine
|
ductless-secretes hormones
delivered put of cell by exocytosis made somewhere but targets somewhere else to deliver product carried by blood |
|
|
Examples of endocrine
|
estrogen, testosterone, adrenaline
|
|
|
connective tissue
|
most abundant tissue found in humans
|
|
|
matrix components
|
ground substance and fiber (proteins)
|
|
|
fiber
|
protein molecules found in matrix area, collagen, elastic, reticular
|
|
|
ground substance
|
watery, hard, rubbery, varies in what it contains & consistency
|
|
|
collagen fiber
|
made up of protein
usually long and arranged in bundles very strong & tough resistant to stretching strongest fiber most abundant |
|
|
where is collagen fiber found?
|
ligaments & tendons
skin & hair |
|
|
elastic fiber
|
protein-elastin
strong ability to stretch & bend does lose stretch bundles of fiber cylindrical |
|
|
where is elastic fiber found?
|
skin, blood vessels, lungs
|
|
|
reticular collagen
|
thinner in weavy form, strong
|
|
|
where is reticular collagen found?
|
in areas where connective tissue supports something
|
|
|
cells in connective tissue
|
less numerous, further apart, not densely packed
vascular-bloodvessels associated with nerves |
|
|
vascular
|
contains blood vessels associated with nerves
|
|
|
avascular
|
no blood vessels or nerves
|
|
|
loose connective tissue
|
most abundant
|
|
|
3 types of loose connective tissue
|
areolar
adipose reticular |
