Cards

Term
the study of tissues
Definition
histology
Term
covers exposed surfaces, lines internal passageways, and chambers and forms glands
Definition
epithelial tissue
Term
list the functions of epithelial tissue
Definition

1)  provide physical protection

2)  control permeability and absorption

3)  provides sensation

4)  produce specialized secretions

Term
______ are especially abundant on epithelial surfaces where absorption and secretion take place, such as along portions of the digestive and urinary tracts
Definition
microvilli
Term
a ____ ______ is formed by the fusion of the outer layers of two cell membranes. Bands of this encircle the apical portion of many epithelial cells, preventing the diffusion of fluids and solutes between the cells.
Definition
tight junction
Term
_______ are abundant between cells in the superficial layers of the skin. As a result, damaged skin cells are usually lost in sheets rather than as individual cells. it gives the epithelium its strength
Definition
desmosomes
Term
what are the three cell shapes?
Definition
squamous, cuboidal and columnar
Term
most delicate type of epithelium. ex respiratory exchange surfaces (alveoli), the lungs, the linin gof the ventral body cavities and the lining of the heart and blood vessels.
Definition
single squagmous epithelium
Term
the simple squamous epithelium that lines the ventral body cavities is called __________
Definition
mesothelium
Term
the pleura, peritomeum each contain a superficial layer of _________
Definition
parietal layer
Term
the simple squamous wpithelium linin gof th einner surface of the heart and all the blood vessels is an _______
Definition
endothelium
Term
this epithelium is generally located where mechanical stresses are severe. the cells form a series of layers. ex surface of skin, esophagus and anus.
Definition
stratified squamus epithelium
Term
the thyroid gland contains chambers called ______ ______ that are lines by a cuboidal secretory epithelium
Definition
thyroid follicals
Term
are relatively rare and are located along the ducts of sweat glands and in the larger ducts of the mammary glands.
Definition
stratified cuboidal spithelia
Term
typically posses cilia. epithelia of this type line most of the nasal cavity, the trachea, the bronchi and portions of the male reproductive tract.
Definition
pseudostratified columnar epithelial cells
Term
flat in appearance; found lining the skin and first line of defense. which type of epithelial tissue is this?
Definition
squamous
Term
which epithelial tissue is shaped like little squares/hexes and found in the lining of the urinary tubes? it also secretes and absorbs material.
Definition
cuboidal
Term
which epithelial tissue is shaped like columns, secretes and absorbs material and is found lining the trachea?
Definition
columnar
Term
which epithelial tissue is of the urinary bladder?
Definition
transitional
Term
A gland that secretes hormones into the bloodstream for distribution throughout the body. hormones that are released directly into the surrounding interstitial fluid. ductless.
Definition
endocrine gland
Term
glands that secrete onto an epithelial surface
Definition
endocrine
Term
involves the loss of cytoplasm as well as the secretory product. mammory gland
Definition
apocrine
Term
destroys the gland cell. ex sebaceous gland
Definition
holocrine
Term
the product is released from the secretory vesicles by exocytosis
Definition
merocrine
Term
are also known as adipose cells, or fat cells. contains a single, enourmous lipid droplet.
Definition
adipocytes
Term
most of the volume of ___ ____ ____ is occupied by fibers.
Definition
dense connective tissue
Term
dense connective tissues are aften called _____
Definition
collagenous
Term
form an interwoven meshwork in no consistent pattern. these tissues, strengthen and support areas subjected to stress from many directions.
Definition
dense irregular connective tissue
Term
a single cell type accounts for almost half the volume of blood and is the reason we associate the color red with blood.
Definition
red blood cell or erythrocyte
Term
a ______ is generally set apart gfrom surrounding tissues by a fibrous _______.
Definition
cartilage, perichondrium
Term
cartilage cells or ______ are the only cells in the cartilage matrix
Definition
chondrocytes
Term
the most common type of cartilage
Definition
hyaline cartilage
Term
lacunae in the matrix contains osteocytes or bone cells ...
Definition
osteocytes
Term
lines passageways and chambers, including the digestive, respiratory, reproductive and urinary tracts that communicate with the exterior.
Definition
mucus membranes
Term
movement is produced by a _______ ________ which is specialized for contraction.
Definition
muscle tissue
Term
smooth muscle tissue has no
Definition
striations
Term
known as nervous tissue, is specialized for the conduction of electrical impulses from one region of the body to another.
Definition
neural tissue
Term
the first abnormality to be observed it _______ a change in the normal shape, size and organization of tissue cells.
Definition
dysplasia
Term
_______ is a structural change that dramtically alters the character of the tissue
Definition
metaplasia
Term
______ tissue organization breaks down
Definition
anaplasia
Term
body membrane-squamous spithelial cells
Definition
cutaneous membrane
Term
membrane that produce mucus - line the cavities that open to the outside of the body digestive, respiratory, reporductive and urinary tracts.
Definition
mucous membrane
Term
body membrane that produces serous fluid, epi cells supported by connective tissue, line internal cavities that are not open to outside; plural (lungs), pericardial (heart), pertioneal (organs).
Definition
serous membrane
Term
body membrane that produce synovial fluid - line the joints of the body.
Definition
synovial membrane
