1. Tissues groups of closely associated cells that perform related functions and are similar
in structure
2. What are the four 1. epithelial tissues (epithelium)- sheet of cells covering body surface or lining a
major categories body cavity
of tissues? 2. connective tissue- includes c.t. proper (fat and ligaments) cartilage, bone, and
blood, provides support
3. nervous tissue- main component of the nervous system provides control
4. muscle tissue- includes skeletal, cardiac, and smooth muscle, provides move-
ment
3. To perform specif- organs. such as stomach, heart, kidney, and lungs
ic functions the
tissues are orga-
nized into ___
4. 1. Epithelia and the tissues that cover the external body surface (epidermis) lines its cavities and
Glands- Epithelia tubules and generally "marks off our inside from our outsides"
5. Glands develop Epithelial membrane
from__
6. Epithelia occurs interfaces between two different environments
at the ___
7. What are the 1. protection
functions of ep- 2. absorption
ithelia 3. filtration
4. secretion
5. diffusion
6. sensory reception

Unique charac- 1. Cellularity- composed almost entirely of cells
teristics of Ep- -mostly just cells
ithelia 2. Special contacts- form continuous sheets held together by tight junctions and
desmosomes
- how cells stick together) surfaces
3. Polarity- apical (upper free) and basal (lower attac
4. Supported by connective tissue- reticular and basal laminae (basement mem-
brane)
-north and south
-deep to epithelium
5. Avascular but innervated- no vessels, has nerves
6. High regenerative capacity- rapidly replaces lost cells by cell division
-grows all the time
9. Epithelia are clas- 1. arrangement- or relative number of layers (first name of tissue)
sified according 2. cell shape (last name of tissue)
to two criteria
10. Arrangement of 1. simple: consisting of one layer of cells attached to the basement membrane
epithelia 2. stratified: consisting of two or more layers of cells
11. Types of epithe- 1. squamous- cells wider than tall (plate like)
lia- cell shape 2. cuboidal- cells are as wide as tall (cube like)
3. columnar- cells are taller than they are wide (column like)
12. Stratified epithe- according to the cells at the apical surface of the epithelial membrane, not those
lia are named resting on the basement membrane
13. 2 other types of 1. pseudostratified epithelium
epithelia - actually a simple columnar epithelium one layer of cells, but because its cells vary
in height and the nuceli lie at different levels above the basement membrane it
gives a false appearance of being stratified. (this epithelium is often ciliated)
2. Transitional epithelium

-Stratified squamous epithelium are formed of rounded or plump cells with the
ability to slide over one another to allow the organ to be stretched.
ONLY found in urinary systems e.g. bladder
14. What type of ep- Transitional. the shape at the top is domed because it stretches.
ithelia is only
found in the uri-
nary system?
15. What type of ep- Pseudostratified Ciliated Columnar Epithelium (technically only has one layer)
ithelia is always
ciliated?
16. The structure of function
epithelium re-
flects its ___
17. 1. Simple squa- a single layer of flat cells with disc shaped nuclei and sparse cytoplasm
mous epithelium
18. Function- Simple Passage of materials by passive diffusion and filtration and secretes lubricating
squamous ep- substances in seorsae (membranes)
ithelium -expect things to pass through it such as gases
19. Special Types- 1. Endothelium (inner covering)- slick lining of hollow organs
Simple squa- 2. Mesothelium (middle covering)- lines peritoneal, pleural, and pericardial cavi-
mous epithelium ites, covers visceral organs and those cavities
20. Location- Simple 1. renal corpuscles

ithelium 3. lining of heart, blood and lymphatic vessels and ventral body cavity (serosae)
