name four types of tissue
muscle, epithelial, nervous, connective
characteristics of epithelial tissue
avascular, tightly packed cells, basement membrane, free surface, fast regeneration,
nerve supply
functions of epithelial tissue
physical protection, control permeability, provide sensation, absorbtion and secretion
function of basement membrane
control permeability, provide attachment for cells, place for mitosis
what is basement membrane made of
collagen and glycoproteins
how is epithelial tissue classified
number of layers and shape
location of epithelial with microvilli
digestive and urinary track for absorbtion and secretion
three cell shapes of epithelial tissue
squamous, cuboidal, columnar (flat, square, rectangular)
Type of epithelium located in a protected region where diffusion takes place or a
slippery surface is needed to reduce friction
simple squamous epithelium
location of simple squamous epithelium
mesothelia lining ventral body cavity, endothelia lining heart and blood vessels
function of simple squamous epithelium
reduces friction, allows diffusion and secretes
tissue with one layer of tall epithelial cells
simple columnar
this type of epithelium protects against physical and chemical attacks
stratified squamous epithelium
type of epithelium making up epidermis of the skin
keratinized, stratified squamous epithelium
type of epithelium found in the oral cavity, esophagus, anus and vagina
non-keratinized, stratified squamous epithelium
what is the purpose of keratinized cells
protects against abrasion and is water resistant
where is cuboidal epithelium found
gland, ducts, kidney tubules
what is the function of cuboidal epithelium
absorbs and secretes
where is stratified cuboidal epithelium found
some sweat gland ducts
how are stratified epithelial tissues named
, according to the cell at the free surface
special characteristic of transitional epithelium
stretches and recoils
where is transitional epithelium found
urinary bladder
Type of epithelium found in the stomach and intestines with microvilli
simple columnar epithelium
Type of epithelium found in the trachea, nasal cavity and portions of the male
reproductive tract
pseudostratified ciliated epithelium
describe characteristics of pseudostratified epithelium
it looks stratified but all of the cells touch the basement membrane and not all cells
reach the free surface
where in the body would you find goblet cells
digestive, urinary, reproductive and respiratory systems
Type of gland that releases its secretions (hormones) directly into the blood
stream
endocrine
Type of gland that releases its secretions through ducts to the surface of the skin
exocrine glands
exocrine glands have three modes of secretions, name them
apocrine, merocrine, holocrine
type of gland that releases only its secretions by exocytosis
merocrine glands
type of gland that releases its secretions in vesicles along with part of the cell's
cytoplasm
apocrine glands
type of gland that bursts to release its secretions
holocrine glands
major type of tissue that makes up an endocrine gland
epithelial tissue
the most common mode of secretion
merocrine
name the only unicellular exocrine glands in the body
goblet cells (mucous)
what are the characteristics of connective tissue
scattered cells, vascular (except cartilage), nerve supply, ground substance, fibers, no
free surface
what determines the characteristic of connective tissue
the matrix
In connective tissue, name the components of the matrix
ground substance and fibers
what is the purpose of ground substance
it binds cells together and slows down pathogens
what is the function of connective tissue
