1. Connective Tissue

2.  Kindly Recite Durood E Pak

3. Connective Tissue
 Function:
- Binds structures together
- Provides support & protection
- Fills spaces
- Produces blood cells
- Stores fat
 For energy, insulation, organ protection

4.  Structure:
- Tissue cells are widely separated by
extracellular matrix
- Can be solid, semisolid, or liquid
 Matrix of connective tissue determine its
properties

5. Fibers of the Matrix
 White fibers – contain collagen which
gives the fibers flexibility and strength
 Yellow fibers – contain elastin more elastic
than collagen but not as strong
 Reticular fibers – thin, highly branched
collagenous fibers that provide support

7. 1. Fibrous Connective Tissue
 Loose (areolar) connective tissue
adipose
 Dense connective tissue
Regular
irregular
 Reticular connective tissue

8. A. Loose (areolar) Connective Tissue
 Lies between other
tissues or between
organs binding them
 Cells made of
fibroblasts – large,
star-shaped cells
 Contains many white
fibers (strong and
flexible) and yellow
fibers (very elastic)

10.  Adipose tissue is a
type of loose
connective tissue
- stores fats,
provides insulation
- found beneath
skin, around kidney
& heart, breast

12. B. Dense Connective Tissue
Regular
 Consists of parallel
bundles of
collagenous fibers
 Found in tendons &
ligaments
 Binds organs together
Irregular
 Bundles run in
different direction
 Found in inner portion
of skin

13. Dense Regular Dense Irregular

14. C. Reticular Connective
 Has reticular cells and
reticular fibers
 Also called lymphatic
tissue
 Found in lymph nodes,
spleen, thymus, and red
bone marrow
 Store and produce white
blood cells
 Part of immune system

16. 2. Cartilage
 The cell
(chondrocytes)
lies in small
chambers called
lacunae
 Matrix is solid yet
flexible
 Lacks direct
blood supply, as
a result, it heals
slowly

17. 3 types
- Hyaline cartilage
- Elastic cartilage
- Fibrocartilage

18. A. Hyaline Cartilage
 Most common
 Matrix contains fine collagenous fibers
Glassy, white, opaque
 Found in the nose, ends of the long bones
and ribs, rings in the trachea

20. B. Elastic Cartilage
 Contains elastic and
collagenous fibers
 Found in the outer
ear

22. C. Fibrocartilage
 Matrix contains strong
collagenous fibers
 Function: absorbs
shocks and reduces
friction between joints
 Found in the pads
between the
vertebrae and knee
joints
