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
structure is one layer, hexagonal column shaped cells
simple columnar
function is protection, absorption, secretion
simple columnar
location of simple columnar
stomach, intestine, gall bladder, uterine tubes
structure is one layer, multi shaped cells with nuclei at varied heights
pseudostratified columnar
function is protection and secretion
pseudostratified columnar
location of pseudostratified columnar
male urinary tracts
structure is thin, flat, irregular, multiple layer cells
stratified squamous
function is protection against frequent abrasion
stratified squamous
location of stratified squamous
skin, mouth, throat, esophagus, rectum, anus, vagina
structure is multiple layered, hexagonal shaped boxes
stratified cuboidal
function is secretion
stratified cuboidal
location of stratified cuboidal
some ducts
structure is multiple layers, hexagonal column shaped cells
stratified columnar
function is protection and secretion
stratified columnar
location of stratified columnar
pharynx, anus
strucuture is multiple layers and can change shape
transitional
function is expansion and recoil without tearing
transitional
location of transitional
urinary bladder, renal pelvis
females urinate blank than males
more
several glandular epithelial cells put together equals
gland
two types of glands
exocrine, endocrine
gland that secretes products into ducts that open on a surface
exocrine
gland that secretes products into tissue fluid or blood
endocrine
two types of exocrine glands
unicellular, multicellular
single cell and goblet cell are blank exocrine glands
unicellular
secretory sheets, simple, and compound exocrine glands are blank
multicellular
two types of multicellular exocrine glands
simple, compound
one large sheer covering a surface and rarely have ducts or pockets and is an exocrine multicellular gland
secretory sheets
have one distinct duct and can be tubular, coiled or alveolar and is multicellular exocrine gland
simple
a multicellular exocrine gland that has many distinct ducts and can be tubular, coiled, or alveolar
compound
three types of exocrine glands
merocrine, apocrine, holocrine
exocrine gland that secrete products by exocytosis. ex salivary gland
merocrine
vesicles within cytoplasm bring product to the surface
exocytosis
exocrine gland that pinches off of cell portion and the product is within this portion. ex. mammary glands
apocrine
exocrine gland that product accumulates in cytosol and cell ruptures and becomes the product. ex. sebaceous glands
holocrine glands
three traits of connective tissue
most abundant, multiple functions, spread apart, able to reproduce, well nourished, vary in structure
connective tissue blank occur on free surface
does not
cartilage and tendons are unlike other connective tissue because it does not have blank
good nerve/ blood supply
all connective tissue is derived from blank cells
mesenchymal cells
stem cells that differentiate into the multitude of cell types in all connective tissue
mesenchymal cells
this is secreted by cells, has protein fibers and ground substance
extracellular matrix
connective tissue is composed of these two things
extracellular matrix, cells
connective tissue blank produce the matrix
cells
cells rarely blank due to the extracellular matrix
touch
three functions of connective tissue
bind structures, support, protection, fill spaces, store fat, produce blood, repair damage, protect against infection, transport fluids & dissolved materials
connective tissue with cells and fibers in gel like ground substance
connective tissue proper
two types of connective tissue proper
loose, dense
connective tissue proper that is areolar, adipose, reticular
loose
connective tissue proper that is regular, irregular, elastic
dense
produce protein fibers in connective tissue proper
fibroblasts
white blood cells that consume damaged cells and invaders in connective tissue proper
fixed macrophages
fat cells in connective tissue proper
adipocytes
produce melanin in connective tissue proper
melanocytes
