Anatomy Tissue Part 1 Test Flashcards
Merocrine gland
Watery, protein-rich fluid
Serous gland
Watery fluid w/high concentration of enzymes
Mucous gland
Thick fluid rich in glyco-proteins
Apocrine gland
Lose portions of their glandular cell bodies
Holocrine gland
Entire gland lyses during secretion
Goblet cells are generally associated with
Columnar cells
Epithelial tissues are nourished by the process of
Diffusion
3 characteristics of the tissue that forms the inner lining of the respiratory tact
Pseudo-stratified, mucus secreting, ciliated
The tissue through which gases are exchanged between the air and the blood in the lung is
Simple squamous
Basement membranes occur between
Epithelium & Connective tissue
3 functions of epithelial tissue
Absorption, protection, diffusion
4 basic tissue types
Epithelium, connective, muscle, nervous
Epithelium consisting of many layers of cells in which the outer layers are flat and thin and the basal layers are cuboidal or columnar would be called
stratified squamous epithelium
Epithelium which appears to be cubelike when an organ is relax and flattened when the organ is distended by fluid is called
Transitional epithelium
Epithelium that consists of a single layer of cells in which some cells are tall and thin and reach the free surface and others do not; however, all cells touch the basement membrane is
pseudostratified epithelium
You are examining a slide containing tissue from the lining of a single organ. On one day, the epithelial cells appear to be stratified cuboidal, and on another day when the slide was made, the sales appear to be squamous. From which organ was the tissue most likely taken?
Lining of the urinary bladder
Epithelial cells can be classified according to shape. What are the characteristic shapes of epithelial cells?
taller than wide, cube, flat
Simple squamous epithelial tissue is made up of
single layer of flat, scale-like cells
4 characteristics of epithelial tissue
avascular, basement membrane, free surface, minimal matrix
Cylindrical processes of some cells specialized for absorption which increases the surface area of the cell are
microvilli
The process by which stratified squamous cells move to the surface layers and full with protein is called
Keratinization
What type of gland secretes substancees into ducts that open onto a surface?
Exocrine gland
3 types of exocrine glands
merocrine, apocrine, holocrine
Where is pseudostratified epithelium found?
respiratory tract
Where is simple squamous epithelium found?
alveoli and capillaries
Where are simple cuboidal epithelium located?
Ducts of glands
Where are transitional epithelium found?
Urinary tract
Found within columnar or cuboidal epithelium; specialized for secretory activities
glandular
Generally two or three layers
stratified cuboidal
Are ciliated; appears to be layered
pseudostratified
Protects body surfaces subjected to abrasion; many layers; lower layers are cuboidal or columnar; upper layers are squamous
stratified squamous
Lines ducts of glands; single layer of cells that are about as wide as they are tall
simple cuboidal
Changes cell shape and layer number with distention; can be stretched to accommodate fluid
Transitional
have microvilli; found lining stomach & intestines; absorption
simple columnar
layers of cells that are taller than they are wide
stratified columnar
Well adapted for diffusion and filtration
simple squamous
