Tissues Flashcards
what are the 4 primary tissue types
Epithelia
Connective
muscle
nervous
what does epithelial do
covers and lines
what is connective tissue
provides support
what doe muscles support
movement
nervous support
controls the work
structures seen with the naked eye
is called the gross
why are epithelia’s avascular
because they are packed too tight .
desmesomes
connect the plasma membranes of adjacent cells
gap junctions
cell linked by tubular channel proteins
basement membrane
cement cells to underlying tissue varies
non living fibers
prevents cells from being torned off
simple cuboidal
look like ice cubes
nuclei aligned single row
found in areas where absorption occurs
simple columbar
single columns
aligned in a row at base cell
absorptive and goblet cells
simple squamous
delicate and thin
flat and smooth
you can find this in animal body in the cavalry area and lungs
stratified squamous
multilayer
protect underlying tissues
found in the oral cavity
and skin has them
stratified cubical epithelium
two layers
sweat glands, salivary glands
stratified columnar epi
rare type of epithelia
in select parts of respatory
and digestive and reproductive system
protections and secrection
pseudostratified columnar
one layer but looks like multi layers
most are ciliated
cells are attached to the basement membrane
raspatory tracts and portions of male tracts
transitional epithelium
urinary systems
leak proof membrane
endocrine glands
do not have ducts
hormonal glands
exocrine glands
discharge secretions via ducts
( anal glands)
unicellular and multicellular
the pancreas is the only what
gland in the body that’ has endocrine and exocrine function
unicellular exocrine gland
is the ductless globet cell
( MAKES MUCOUS )
MUCIN
WHAT IS MUCOUS CALLED
MUCIN
multicellular exocrine
