9. The Classification of Tissues
What is a tissue?
A group of cells working together
4 types of tissues:
Epithelial Tissue
Muscle Tissue
Connective Tissue
Nervous Tissue

10. Epithelial Tissue Covers surfaces of the body 3 types: Squamous
Functions:
Protection
Absorption
Filtration
Excretion
Secretion
Sensory reception
3 types:
Squamous
Cuboidal
Columnar
* Can be Simple or Stratified

11. Simple Squamous

12. Stratified Squamous

13. Simple Cuboidal

14. Stratified Cuboidal

15. Simple Columnar

16. Muscle Tissue
3 types:
Smooth
Skeletal
Cardiac

17. Smooth Muscle: Found in the walls of hollow organs:
Digestive tract
No striations are visible
Uninucleate

18. Skeletal Muscle Attaches to skeleton Under voluntary control
Moves the limbs and other external body parts
Multinucleate
Obvious striations
Nuclei lie on the periphery of the cells

19. Cardiac Muscle Found only in the heart Striations
Branching and uninucleate
Intercalated discs

20. Connective Tissue Numerous kinds of connective tissues:
Cells spaced out in a non-living matrix

21. Connective Tissue Numerous kinds of connective tissues: Areolar
Cartilage
Bone
Blood

22. Nervous Tissue

23. Neurons
Axon
Dendrite
Cell Body
