Chapter 2 Notes Flashcards
1
Q
Tissue
A
One or more similar cells having a specific function
2
Q
Epithelial
A
Tissue that covers surfaces and line cavities
3
Q
Epithelial tissue structure
A
- stratification/ stratified
- 1 layer= simple
- 2 or more layers= stratified
4
Q
Epithelial tissue function
A
To cover a surface or line a cavity
5
Q
Epithelial tissue types
A
- simple/stratified squamous
- simple/stratified cuboidal
- simple/stratified columnar
- pseudostratified columnar
6
Q
Simple squamous
A
- scale like, flat, 1 layer
- involved with diffusion (high concentration to low concentration until everything is even), and filtration
- air sacs of the lungs, line blood vessels
- flexible for blood can flow through
7
Q
Simple cuboidal
A
- square like, round neuclei in center, 1 layer
- filtration
-kidney tubules, surface of ovaries
8
Q
Simple columnar
A
- column, elongated nuclei, 1 layer
- absorption of nutrients, excretion of mucus
- microvilli of digestive tract (lining), trachea
9
Q
Pseudostratified columnar
A
- looks like multiple layers it is actually 1
- all cells attached to basement membrane
-secretion, movement across a surface
-lungs (moves debris out)
10
Q
Stratification
A
Many layers, look at the surface
11
Q
Stratified squamous
A
- more than one layer
-nuclei squished/flat
-protection - skin, lines mouth and throat
12
Q
Stratified cuboidal
A
- more than 1 layer
- round nuclei
- protection
- sweat glands, memory glands, saliva
13
Q
Stratified columnar
A
- more than 1 layer
-elongated nuclei - rare in humans
-parts of male urethra
14
Q
Transitional
A
- could have 6-10 layers
- stretched = 3 layers
- at surface cells are dome shaped
- bladder, urethra and utterers
15
Q
Connective tissue (CT) function
A
- connects tissue
- protection
-everywhere in the body
