Types of CT:
|
-Embryonic
-Loose -Dense -Reticular |
|
|
2 types of Embryonic CT:
|
-Mesenchymal
-Mucous |
|
|
What does mesenchymal CT give rise to?
|
Most cells in the loose connective tissue.
|
|
|
What does the gel-like ground substance of the mesenchymal CT contain?
|
Reticular fibers
|
|
|
Mucous CT is found in:
|
the umbilical cord
|
|
|
What does mucous CT contain?
|
Jelly like matrix of Hylauronate and Fibrillar collagens.
|
|
|
What is the function of LOOSE connective tissue?
|
To wrap and cushion organs and hold tissues together.
|
|
|
How does Dense CT compare to loose?
|
It has more fibers and fewer cells
|
|
|
2 types of Dense CT:
|
-Regular
-Irregular |
|
|
What is Irregular CT intended for?
|
Withstanding tension in multiple directions - structural strength.
|
|
|
3 Places where Irregular CT is located:
|
1. Dermis of skin
2. Digestive tract submucosa 3. Fibrous capsules of visceral organs and joints |
|
|
What layer of the dermis is irregular CT found in?
|
The reticular layer.
|
|
|
How is REGULAR dense CT different from irregular?
|
-More densely packed
-Parallel orientation of collagen bundles |
|
|
What is the function of regular dense CT?
|
Tensile strength - in one direction
|
|
|
What structures contain regular dense CT?
|
Ligaments, tendons, and aponeuroses
|
|
|
What type of collagen and structure of CT is in the cornea?
|
Type 1 collagen
-Dense regular CT - oriented orthagonally at right angles. |
|
|
What type of collagen is in Reticular Connective Tissue?
|
Type 3
|
|
|
Function of Reticular connective tissue:
|
Support of organ parenchyma
|
|
|
What organs contain reticular connective tissue?
|
lymphoid
|
|
|
3 lymphoid organs:
|
-Bone marrow
-lymph nodes -Spleen |
