1. TYPES OF HUMAN TISSUES

3. Four Basic Kinds of Tissues Epithelial Tissue Connective Tissue Muscle Tissue Nervous Tissue

5. Muscle Tissue Muscle Tissue: – Associated with the bones of the skeleton, the heart and in the walls of the hollow organs of the body. Muscle Tissue Functions: – Movement – Locomotion – Maintains posture – Produces heat – Facial expressions – Pumps blood – Peristalsis

6. FUNCTIONS OF MUSCLES SKELETAL: VOLUNTARY: SUPPORTS SKELETAL SYSTEM, MOVEMENT: STRIATED: TIRES EASILY SMOOTH: INVOLUNTARY: LINES MANY INTERNAL ORGANS: NO STRIATIONS; NEVER TIRES CARDIAC: INVOLUNTARY: COMBINATION OF SKELETAL AND SMOOTH: FOUND ONLY IN THE HEART: NEVER TIRES

7. NERVE TISSUE

8. Nervous Tissue Nervous Tissue: – 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.

9. Connective Tissue Connective Tissue: – 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. Types of Connective Tissue Bone Ligaments Tendons Cartilage Fat Blood

11. TYPES OF CONNECTIVE TISSUE LIGAMENT: CONNECTS BONE TO BONE: CONNECTIVE TISSUE

12. TENDON: CONNECTS MUSCLE TO BONE: CONNECTIVE TISSUE

13. BLOOD: CONNECTIVE TISSUE: PRODUCED IN THE BONES:

14. TRANSPORTS NECESSARY NUTRIENTS, REMOVES TOXINS FROM BODY, REGULATES BODY FLUID ELECTROLYTES, CARRIES OXYGEN, AND CONTROLS pH: CONNECTIVE TISSUE

15. CONNECTIVE TISSUE: FAT CELLS: CUSHION, INSULATION, ENERGY STORAGE

16. CARTILAGE: MORE FLEXIBLE THAN BONE: GIVES SUPPORT: NOSE, EARS, ENDS OF JOINTS: SOME CARTILAGE TURNS INTO BONE, SOME DOESN’T

18. 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.
