1. Anatomy and Physiology I
Review of Tissue Types

2. Key Terms H????: the study of tissues. Tissues:
groups of which are similar in structure and which perform common or related functions.

3. Key Terms Histology: the study of tissues. Tissues:
groups of cells which are similar in structure and which perform common or related functions.

Name 2

7. Epithelial Tissue Epithelial Tissue Locations:
Covers the body
Lines the cavities, tubes, ducts and blood vessels inside the body
Covers the organs inside body cavities
Epithelial Tissue Functions:
Protection from physical & chemical injury,
Protection against microbial invasion,
Contains receptors which respond to stimuli,
Filters, secretes & reabsorbs materials and
Secretes serous fluids to lubricate structures.

8. Connective Tissue Connective Tissue: Connective Tissue Functions:
Most abundant & found where??
Connective Tissue Functions:
name 2

9. Connective Tissue Connective Tissue: Connective Tissue Functions:
Most abundant & widely distributed tissue
Connective Tissue Functions:
Connects, binds and supports structures,
Tendons, ligaments, etc.
Protects & cushions organs and tissues,
Insulates (fat) and
Transports substances (blood).

10. Muscle Tissue
Muscle Tissue:
name 3
Muscle Tissue Functions:

11. Muscle Tissue Muscle Tissue: Muscle Tissue Functions:
Associated with the bones (skeletal) of the skeleton, the heart (cardiac) and in the walls of the hollow organs (smooth) of the body.
Muscle Tissue Functions:
Movement
Locomotion
Maintains posture
Produces heat
Facial expressions
Pumps blood
Peristalsis

12. Nervous Tissue Nervous Tissue: Nervous Tissue Functions:
Main component of the nervous system,
Where do we find this?
Nervous Tissue Functions:
name 2

13. Nervous Tissue Nervous Tissue: Nervous Tissue Functions:
Main component of the nervous system,
ie., brain, spinal cord & nerves.
Nervous Tissue Functions:
Regulates & controls body functions
Generates & transmits nerve impulses
Supports, insulates and protects impulse generating neurons.

19. Squamous Epithelium Simple – one cell thick
Forms solid layer of cells which line blood vessels, body cavities & cover organs in body cavities
Stratified – multiple layers
Forms epidermis

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

21. Columnar Epithelium Simple – one cell thick
Column shaped (long & narrow)
Line digestive tract where reabsorption & secretion occurs.
Pseudostratified – gives the appearance of more than one layer of columnar epithelial cells

22. Specific Connective Tissue Types:
Adipose
Bone
Hyalaine cartilage

23. Connective - Adipose Honeycomb or chickenwire appearance
Stores energy (fat)
Insulates
Supports & protects organs

24. Connective - Bone Tree ring-like appearance Supports & protects
Mineral storage
Fat storage
Blood cell production

25. Connective – Hyaline Cartilage
Supports while providing flexibility
Absorbs compression between bones in joints (articular cartilage)
Holds open respiratory passages
Most abundant type of cartilage in body

26. Specific Muscle Tissue Types:
muscle (skeletal)

27. Muscle - Skeletal Muscle fibers (cells) long, parallel & cylindrical
With many nuclei (multinucleate)
Striations (cross stripes run perpendicular to the cells
Produce voluntary movement
Locomotion
Heat

28. Specific Nervous Tissue Types Nervous – Neuron
Branching cells with many long processes
Large central nucleus
Transmit impulses from one area of the body to other areas
Regulate activities through neuron impulses

29. Human Tissues Additional Review
