TESTE DEIN WISSEN
How many tissue classes are there?
Lösung anzeigen
TESTE DEIN WISSEN
There are 4:
1. Epithelial- line tubles 
2.connective - skeleton 
3.muscular- cardiac, skeletal, smooth 
4.nervous

TESTE DEIN WISSEN
What are CAMs and the 3 different types of junctions 
Lösung anzeigen
TESTE DEIN WISSEN
CAMs: cell adhension molecules 

1. Desmosomes: attach cells to other cells - using cadherins 
-cadherins: bind cells together like Velcro 
- desomosomes attach to intermediate filaments of cytoskleteon 

2. Tight junctions:
- controls movement of solute and fluids between Cells 
- they must move trans cellular via specific receptors 
- no movement is - paracellular patway 

3. Gap junction:
- CAMs- connexins 
- allows passage of small molecules such as ions amd synchronises activity between cells

TESTE DEIN WISSEN
What are the diff between collated columnar and noncil
Lösung anzeigen
TESTE DEIN WISSEN
Noncil:
- have microvilli 
- increase in S.A and water absorption in GI tract 
- unicellular glands (goblet cells) present:
- secrete mucus apically 

ciliated:
- mucus from goblet cells swept along by cilia 
- found in respiratory and uterine tubes

TESTE DEIN WISSEN
Exocrine: — secrete onto body surface 
- connected by tubes 

endocrine: secretes horomones into blood stream to organs 
- ductless gland

-forms boundaries 

2. Connective:
-material found between cells 
-supports and bind structures together 

3. Muscles:
movement
