4 types of tissues
|
1. epithelial
2. connective 3. muscular 4. neural |
|
|
Covers body surfaces,
attached to basal lamina, classified based on shape, arrangement, and function |
epithelial
|
|
|
Functions of epithelial tissues
|
physical protection,
controls permeability, sensation, secretion - gland cells |
|
|
Apical Side
|
exposed surface
- microvili - cilia |
|
|
microvili vs. cilia
|
microvili - extensions of cell membrane that increase surface area, intestines
cilia - motile protein fibers with rhythmic action, trachea |
|
|
Basal lamina
|
superficial,
adjacent to basement membrane, barrier to diffusion |
|
|
Simple squamous
|
single layer, flat
easily damaged, Absorptin, diffusion, reduce friction |
|
|
simple cuboidal
|
single layer, cube shaped,
sentral nuclei, absorption, secretion, limited protection covers ovaries, lines kidney tubules and ducts of glands |
|
|
simple columnar
|
single layer, elongated cells,
nuclei near basement membrane, lines uterus and organs of digestive tract Protection, absorption, secretion |
|
|
pseudostratified columnar
|
vary in shape,
have cilia on apical surfacem goblet cells lines respiratory and reproductive tract protection and secretion |
|
|
stratified squamous
|
many layers, layers near apical surface flattened,
Keratin found here, protection against abrasion lines mouth, throat, vagina, anal canal |
|
|
stratified cuboial
|
RARE
lines ducts of sweat glands, mammary glands |
|
|
strafied columnar
|
RARE
in pharynx, urethra, anus, largare excretory ducts |
|
|
Transitional
|
can change in response to tension,
lines bladder and passage ways of urinary tract |
|
|
Glandular
|
specialized to secrete and produce substances into ducts/body fluids
exocrine or endocrine |
|
|
Exocrine vs. endocrine
|
exocrine - has a duct, goes to body surface
endocrine - secretes product into tissue fluid or blood |
