|
What are the 3 things that CT classification is based on?
|
1. character of ground substance
2. type & arrangement of fibers 3. type of cells |
|
|
The presence of what separates Connective Tissue from ECM?
|
The presence of CELLS
ECM is acellular* |
|
|
what are three characteristics of Ground Substance?
|
Viscous, “slippery”, & amorphous –
|
|
|
Describe Loose (areolar) CT.
Vacularized? Ground Substance present? What cells are present (5)? which is more abundant, cells or fibers? |
Well vascularized
Abundant ground substance Fibroblasts, Macrophages, Lymphocytes, Mast Cells, Plasma Cells Cells >>Fibers |
|
|
What two tissue layers are CT associated with?
|
Adventitia and Lamina Propria
|
|
|
What is Lamina Propria?
|
Lamina propria is a special name given to loose connective tissue that is associated with mucosal epithelium and glands (digestive)
|
|
|
Reticular Tissue constitute what? Are found where? Cells (</=/>) fibers?
|
constitute the major portion of the matrix.
are found only in reticular CT and are not easily visible in LM Liver, bone marrow, endocrine glands Cells > Fibers |
|
|
Adipose Tissue
Structure: Function (4): Location: |
closely packed adipocytes; nucleus squeezed to one side by large fat droplet
Stores energy, protects, cushions, insulates Subcutaneous; covers and surrounds some organs |
|
|
What are the two types of Dense connective tissue?
|
Dense Regular
Dense Irregular |
|
|
Dense IRregular Connective Tissue:
what does it look like? What 2 cells are in it? Where is it (4 places)? More fiberous or cellular? |
Fiber bundles have NO PARTICULAR ORIENTATION (most abundant type of dense CT).
Contains fibroblasts, macrophages Found in dermis, organ capsules, deep fascia, CT sheaths. Fibers> cells |
|
|
How does Collagen stain?
|
Collagen loves the EOSIN stain, picks it up Quick! So if you have fibers, you have pink.
|
|
|
Dense Regular CT:
arrangement/orientation? associated structures? more cellular or fibrous? |
Fiber bundles arranged in UNIFORM MANNER
Contains fibroblasts / fibrocytes think TENDONS and LIGAMENTS Fibers> Cells |
|
|
What only two words are associated with Dense Regular CT?
|
“TENDON” and “LIGAMENT”;
Most of the body is dense IRregular |
|
|
evaluate Elastic Tissue for:
fiber content fibrous or cellular dominance locations in the body (3 main 2 minor) |
Sparse collagen fibers and many elastic fibers
Some fibroblasts present Usually Fibers > Cells cartilage, large blood vessels (aorta), ligaments, and sparse in dermis and lung |
