ECPI BIO 111 DR.T Chapter 5 Exam Questions
With 100% Verified Correct Answers.
Simple is:
one layer
Stratified is:
multiple layers
Pseudostratified is:
one layer of epithelial cells that look like it consist of multiple cell layers
microvilli is:
increase surface area for absorption
cilia is:
hairlike projections that extend from plasma membrane and are used for locomotion
histology
the study of tissue
What are the 4 major tissue types?
1. epithelial tissue
2. connective tissue
3. muscular tissue
4. nervous tissue
Epithelial tissue location:
-cover body surface
-cover and line internal organs
-compose glands
,epithelial tissue
cover all major body surfaces
Epithelial tissue features:
-lack blood vessels
-cell readily divide
-cells are tightly packed
are epithelial tissue avascular?
yes, the tissue lacks blood vessels (avascular)
epithelial tissue functions:
-protection
-secretion
-absorption
-excretion
What are the Epithelial cell shapes
squamous, cuboidal, columnar
What are the epithelial cell layers
-simple (one layer of cells)
-stratified (2 or more layer of cells)
-pseudostratidied (appears layered, but is not)
simple squamous epithelium
-single layer of thin, flat cell
-substances pass easily through air sacs (alveoli) & capillaries
-thin and delicate, can be damaged
-found in diffusion & filtration sites
, -lines air sacs (alveoli) & capillaries
-lines blood & lymphatic vessels
Simple squamous epithelium
simple cuboidal epithelium
-single layer of cube-shape cell
-secretion and absorption
-lines kidney tubules, thyroid follicles
-covers ovaries
-lines ducts of some glands
simple cuboidal epithelium
simple columnar epithelium
-single layer of elongated cells, tall cell
-Nuclei usually at same level, near membrane
-sometimes have microvilli
-sometimes have goblet cells (secrete mucus)
-lines uterus
simple columnar epithelium
stratified squamous
-Many cell layers; thick
-Protective layer
-Outermost cells are flat
-Deeper cells are cuboidal
-New cells form, push older cells
toward free surface
-Outer layer of skin (keratinized)
-Lines oral cavity, vagina, anal canal
