Epithelial tissue - ANSWER A body tissue that covers the surfaces of the body, inside
and out and also secretes.
3 types of epithelium - ANSWER Covering and Lining Epithelium; Glandlular Epithleium
Major functions of epithelial tissue. - ANSWER selective absorptive barriers, regulating
the movement of substances into and out of the body.
Secretory surfaces, comprising the functional units of glandular secretion.
Protective surfaces, such as skin.
Connective tissue - ANSWER provides support for your body and cushions, most
abundant tissue in the body, makes up part of every organ, cells separated by extracellular
matrix.
Muscular tissue - ANSWER moves the body and its parts and generates heat
Nervous tissue - ANSWER control and communication
Tight junctions - ANSWER blocking the passage way in between 2 cells,
Tightly bound together by interlocking membrane proteins.
Adherens junctions - ANSWER is anchoring 2 cells together in (muscle) contraction
1
,Desmosomes - ANSWER anchoring 2 cells together in contraction using a intermediate
filament
Hemidesmosomes - ANSWER anchoring 1 cell to the basement membrane
Gap junction - ANSWER allows communication between 2 cells
Characteristic of epithelial tissue? - ANSWER cells are closely packed together,
Avascular (no blood supply),
Can regenerate tissue very quickly and easily,
Cells are separated from the underlying connective tissue by the basement membrane.
Simple - ANSWER single layer
Pseudostratified - ANSWER only a single layer but looks like more (falsely stratified)
Function of apocrine glands - ANSWER product released through the loss of both the
secretory product and cytoplasm (mammary glands)
Stratified - ANSWER 2 or more layers of cells
Squamous - ANSWER flat cells
Cuboidal - ANSWER cube shaped cells
Columnar - ANSWER column shaped cells
2
,Function of simple squamous epithelium - ANSWER allows materials to pass by
diffusion and filtration
Location of simple squamous epithelium - ANSWER Kidney glomeruli, air sacs of lungs,
lining of heart, blood vessels, and lymphatic vessels, lining of ventral body cavity (serosae)
Function of simple cubodial epithelium - ANSWER secretion and absorption
Location of simple cubodial epithelium - ANSWER kidney tubules; ducts and secretory
portions of small glands, ovary surface.
Function of non-ciliated simple columnar epithelium - ANSWER increased surface area
for absorption. Mucus secretion for lubrication and protection
Location of non-ciliated simple columnar epithelium - ANSWER lines the funcitonal
tracts, such as the gastrointestinal tract, gall bladder
Function of ciliated simple columnar epithelium - ANSWER elimination of foreign
particles.
Location of ciliated simple columnar epithelium - ANSWER lines the uterine tubes and
auditory tubes.

part of the male testes
Location of ciliated pseudostratified columnar epithelium - ANSWER lines the upper
airways of the respiratory tract. Sensory epithelium of olfactory area
3
, Function of ciliated pseudostratified columnar epithelium - ANSWER elimination of
foreign particles and protection.
Function of Non-Ciliated Pseudostratified Columnar - ANSWER absorption and
protection.
Function of non-keratinized stratified squamous epithelium - ANSWER protects the
body against microrbes
Location of non-keratinized stratified squamous epithelium - ANSWER forms moist
linings such as the buccal cavity, esophagus, and part of the cervix.
Function of keratinized stratified squamous epithelium - ANSWER protects the body
from heat, microbes, and damaging substances.
Location of keratinized stratified squamous epithelium - ANSWER forms superficial
layer of the skin
Function of transitional epithelium - ANSWER forms stretchable lining
Location of transitional epithelium - ANSWER lines the ureters, bladder and part of the
urethra.
Glandular epithelium - ANSWER makes up the secreting portion of glands such as the
thyroid gland, adrenal glands, sweat glands, and digestive glands.
Function of endocrine glands - ANSWER secrete their substance directly into the blood
stream; they do not use ducts
