Ch 3 Lec 1 Tissues Flashcards
many tissues make up a blank
organ
tissues are made of similar types of blank
cells
Four primary types of tissues
epithelial, connective, muscle, neural
three characteristics of epithelial tissue
regeneration, polarity, covers all body surfaces, cellularity, attachment, avascularity
do blood vessels run through epithelial tissue?
no
three functions of epithelial tissue
physical protection, control permeability, sensation, secretions
glandular products are made from blank tissue
epithelial
There is blank space between epithelial cells
little
there is no blank matrix in epithelial tissue
intercellular
nutrients are usually supplied through blood in the underlying tissue underneath blank tissue
epithelial
The polar sides of epithelial tissue are…
basal, lateral, apical
basal side grows off a basal blank
lamina
lateral side contacts blank cells and cell blanks
adjacent, junctions
apical side is exposed to blank and has these two specializations
lumen… microvilli, cilia
basal lamina is also known as
basement membrane
lamina lucida means blank
clear layer
lamina densa means blank
dense layer
three types of classification of epithelial tissue
simple, pseudostratified, stratified
function is secretion and absorption epithelial tissue
simple
epithelial tissue whose function is protection
stratified
single layer of cells epithelial tissue
simple
single layer of cells that look stratified
pseudostratified epithelial tissue
two or more layers of epithelial tissue
stratified
four shapes of epithelial tissue
squamous, cuboidal, columnar, transitional
cells are flattened in this epithelial tissue shape
squamous
cells are usually cube shaped or hexagons epithelial shape
cuboidal
tall and cylindrical cells epithelial shape
columnar
shape changes in this shape of epithelial tissue
transitional
any type of epithelium has blank names
two… ex) simple squamous
structure is one layer, thin, flat, irregular
simple squamous
function is absorption, diffusion, reduce friction
simple squamous
location of simple squamous
blood vessels, lungs, kidney tubules, serous membranes
structure is one layer, hexagonal box shaped cells
simple cuboidal
function is absorption, secretion, limited protection
simple cuboidal
location of simple cuboidal
glands, ducts, kidney tubules
