Connective Tissue
General Functions:
- Supports softer organs of body
- Connects parts of body
- Stores fat
- Produces Blood Cells
-
Connective Tissue
General Funtions cont..
Contains Cells embedded in non living extracellular Matrix provides the strenghth
-
Connective Tissue
General Functions :TWO TYPES
-
Fibrous Connective Tissue
FUNCTION:
Provides strength and elasticity
-
Fibrous Connective Tissue
CONTAINS:
fibers and cells embedded in gel-like ground substance (matrix)
-
Fibrous Connective Tissue
CELLS:
Fibroblasts, Macrophages,Lymphocytes, and neutrophhils
-
Fibrous Connective Tissue
FIBERS:
Collagen,elastic and reticular
-
Fibrous Connective Tissue
Four general types:
- Loose
- DenseElastic
- Reticular
-
Fibrous Connective Tissue
Four general type
LOOSE TYPE:
- Surrounds many organs, lines cavities around blood vessels
- Fills spaces between organs, cushioning and protecting them
- Low density meshwork of collagen elastin and fibroblast cells
-
Fibrous Connective Tissue
Four general types
DENSE:
- Forms tendons, ligaments, deeper layers of skin
- Have a much Higher content of bibers organized much more densely
-
FYI: loose connective tissue (x160). In Loose connective tissue the collagen and elastin fibers are arrayed in random Pattern.
-
FYI: Dense connective tissue (x160). In dense connective tissues the fibers are primarily collagen fibers. In tendons and ligaments the fibers are oriented all in the same direction. with fibroblasts occupying narrow spaces between adjacent fibers.
-
Fibrous Connective Tissue
Four general types
ELASTIC:
- surrounds stomach and bladder, maintains shape
- composed in large part of elastic fibers
-
Fibrous Connective Tissue
Four genarl types
RETICULAR:
- Makes up internal framework of soft organs (liver) and the Lympathic System
- Reticular fibers produced by fibroblast known as reticular cells!
-
Specialized Connective Tissues Serve Special Functions
CARTILAGE:
- No blood vesseles; high collagen content
- provides support and cusion between joints
-
Specialized Connective Tissues Serve Special Functions
BONE:
in organic matrix with calcium salts for hardness- provide framework
-
Specialized Connective Tissues Serve Special Functions
BLOOD:
- Fluid matrix of plasma, red blood cells, white blood cells, and platelets.
- Are the Transport Tissue of mammals
-
Specialized Connective Tissues Serve Special Functions
ADIPOSE TISSUE:
- Fat cells
- Function in insulation, protection, and energy storage
-
FYI Cartilage from the trachea (x300)Mature cartilage cells called CHONDROCYTES , become trapped in chambers called LACUNAE within the hard, rubbery ground substance. Ground substance is composed of collagen fibers, Polysaccharides, proteins and water.
-
Adipose Tissue from the substancutaneous layer under the skin(x140) Adipose tissue consits almost entirely of fat cells. The fat deposit within a fat cell can become so large that the nucleus is pushed to the side.
-
diahpram is located betwwen the trachea and the abdomen
