1. Tissue Types

2. Key Terms Histology: ______________________. ____________:
groups of cells which are similar in structure and which perform common or related functions.

3. Four Basic Kinds of Tissues
________________
Connective Tissue
Nervous Tissue

4. Epithelial Tissue Epithelial Tissue Locations:
___________________________
Lines the cavities, tubes, ducts and blood vessels inside the body
Covers the organs inside body cavities
Epithelial Tissue Functions:
___________________________,
Protection against microbial invasion,
__________________________________,
Filters, secretes & reabsorbs materials and
Secretes serous fluids to lubricate structures.

5. Connective Tissue Connective Tissue: Connective Tissue Functions:
_____________________________
Connective Tissue Functions:
________________________________,
Tendons, ligaments, etc.
Protects & cushions organs and tissues,
______________________
Transports substances (blood).

6. Muscle Tissue Muscle Tissue: Muscle Tissue Functions:
Associated with the bones of the skeleton, the heart and in the walls of the hollow organs of the body.
Muscle Tissue Functions:
________________
Locomotion
_________________
Produces heat
Pumps blood
___________________

7. Nervous Tissue Nervous Tissue: Nervous Tissue Functions:
___________________________,
ie., brain, spinal cord & nerves.
Nervous Tissue Functions:
___________________________
Supports, insulates and protects impulse generating neurons.

8. Specific tissue types & representative cell types we will review:
epithelial
_________
Cuboidal
__________
connective
Bone
___________
Areolar
Blood
muscle
nervous

9. Squamous Epithelium Simple – ___________________
Forms solid layer of cells which line blood vessels, body cavities & cover organs in body cavities
Stratified – _______________________
Forms epidermis

10. Cuboidal Epithelium Simple – one cell thick _________________
Cuboid Cells
Simple – one cell thick
_________________
Duct
Line ducts in kidneys, etc, where reabsorption and secretory activities take place.
Cuboid Cells
Duct

11. Columnar Epithelium Simple – ____________
Column shaped (long & narrow)
Line digestive tract where reabsorption & secretion occurs.
Pseudostratified – gives the appearance of more than one layer of columnar epithelial cells
___________-has cilia to help move things

12. Specific Connective Tissue Types:
___________
Bone
______________
Areolar
Reticular

13. Connective - Adipose Honeycomb or chickenwire appearance
________________
Insulates
Supports & protects organs

14. Connective - Bone Tree ring-like appearance _______________
Mineral storage
Fat storage
________________

15. Connective – Hyaline Cartilage
Supports while providing flexibility
Absorbs compression between bones in joints (articular cartilage)
___________________________________
Most abundant type of cartilage in body

16. Connective – Reticular Tissue
____________
Help support lymphoid organs and red bone marrow
____________________________________
Found in kidney, spleen, lymph nodes and bone marrow

17. Connective – Areolar Tissue
_______________
Also found in membranes of blood vessels and nerves
______________________________________________________
Contains reticular fibers

18. Connective – Blood Tissue
Delivers nutrients and oxygen to cells
__________________
Made up of blood cells and plasma(fluid)

19. There are 3 types of muscle tissue:  _________________

20. Review What You’ve Learned…
Muscle Type
Striated?
# of nuclei
Voluntary or Involuntary
Skeletal
Cardiac
Smooth

21. Specific Nervous Tissue Types Nervous – Neuron
Branching cells with many long processes
____________________
Transmit impulses from one area of the body to other areas
