Connective Tissue Flashcards
Describe Abnormal Periorbital ECM and Thyroid Disease
Most common in younger women.
Goitre (extremely swollen thyroid glands).
Autoimmune over activation of fibroblasts in ECM of eye. Resulting in deposition of Glycosaminoglycans and influx of water in the eyes making them have a bulging appearance.
2 types of Supporting Connective Tissue
1. Cartilage
2. Bone
Name the 2 types of Connective Tissue Proper
- Loose (the fibers of loose CT are loosely arranged between cells)
- Dense (more fibres, fewer cells, thicker & more densely packed)
Name a type of Fluid Connective Tissue and list it’s formed elements
Blood is a form of fluid connective tissue. and it’s formed elements include;
Erythrocytes (red blood cells)
Thrombocytes (platelets)
Leukocytes (white blood cells)
- Eosinophil
- Basophil
- Neutraphil
- Monocyte
- Lymphocytes (B & T)
Which 2 Leukocytes realease substances to intensify the inflammatory reaction?
Basophils and Immature Mast Cells.
Which 2 Leukocytes are Phagocytic (engulf and breakdown bateria) ?
Neutrophils and Monocytes.
Name the 2 types of Embryonic connective tissue
- Mesenchyme
- Mucous
Name the two main types of connective tissue
Mature (new-born)
Embryonic (Embryo & Fetus)
Name the 3 types of Loose connective tissue
Areolar
Adipose
Recticular
Name the 3 types of Dense connective tissue
- Regular
- Irregular
- Elastic
The 3 types of Cartilage
- Fibrocartilage
- Elastic
-
Hyline
* Remember F - E - H*
Name the 2 types of Bone
- Compact
- Spongey
Name the 5 types of Mature CT
- Loose
- Dense
- Cartilage
- Bone
- Liquid
Features of Elastic CT
Elastic fibres with fibroblast cells
Function:
Allows organs to stretch, is strong & can recoil to original shape
Examples: lung tissue (recoils in exhailing), elastic arteries (recoil between heartbeats to help maintain bloodflow)
Features of Areolar CT
