2. Tissue

5. Connective tissue

6. Connective tissue, group of tissue that supports, protects, and gives
structure to other tissues and organs in the body.
Connective tissue also stores fat, helps move nutrients and other substances
between tissues and organs, and helps repair damaged tissue.
Definition

7. Connective tissue components
1. Cells
2. Ground substance ( Non fibrous protein)
3. Fibre (collagen, elastic, reticular)
Matrix

9. BONE

10. BONE IS A SPECILIZED CONNECTIVE TISSUE
Components
1. Cells
2. Matrix
Inorganic
Ground substance ( glycoprotein and minerals such
as calcium phosphate, calcium carbonate)
Organic
Fibre (collagen fibre type l)

12. Long bone
• Two knobby ends are called epiphysis
• Two ends are joined by a long Shaft called
diaphysis
• Contain medullary cavity filled with bone
marrow
• Two ends are articulating ends
• Most of the long bones are responsible for
weight bearing
• Example: femur and humerus

13. Short bones
• Structurally Small size
• Cubical or rounded in nature
• Example: carpal bones

14. Irregular bone
• Shape of the bone is ill-defined in nature
• Major mechanical support for the body.
• Example: vertebrae protects the spinal cord

15. Flat bones
• Flat and shallow plate-like bones
• These bones forms boundaries of body cavities
such as thoracic cavity and cranial cavity
• Example : Rips and sternum

16. Other types
• Pneumatic bones
- Bones contain air-filled cavity
- Mainly around the nasal cavity (make the
skull lighter and add resonance of voice)
• Sesamoid bones
-Bone developed within the tendon
