Wk3- Connective Tissue Flashcards
Functions Connective tissue:
- Connecting: bind different tissues together, anchor o? and tissues in places
- Support: b- and c-
- Protection: b-, c-, v- fat, hosts immune elements
- Transport: blood supply
- organs
- Bones and cartilage
- Bone cartilage visceral fat
All connective tissue contained specialised cells, ECM (- ) , protein fibres and ground s- ( viscous sugar lubricant and s- a-)
Extra cellular matrix
Substance
shock absorber
Extra cellular fibres and function:
What are the 3 fibres?
- Co?
- El?
- Ret?
- Collagen
- Elastic
- Reticular
Extra cellular fibres and functions:
Collagen fibres:
S-, long, straight, run down same axis (- directional) found in dense c- tissue (in t- and ligaments
Strong, uni directional, connective , tendons
Extra cellular fibres and functions:
Elastic fibres:
Elastic bands s- and r- , found in d- regular elastic tissue ( aorta in the heart contracts and pumps)
Stretch and recoil
dense
Extra cellular fibres and function:
Reticular fibres:
Thin in? supports found in reticular tissue
l? nodes
Interwoven ,lymph
What are the 6 key cells?
- F- (large , mobile, produce fibres, secrete matrix fibres and ground substance components)
- M- (large, mobile, immune cells that engulf and destroy pathogens)
- P- cells ( immune cells, produce and secrete antibodies)
- M- cells (release histamine/ promote inflammation)
- A- (fat cells, storage of lipids)
- L- (white blood cells/ immune cells)
- Fibroblasts
- Macrophages
- Plasma cells
- Mast cells
- Adipose
- Leukocytes
Connective tissue can be classified into 2 categories:
- Connective tissue p-
- S- connective tissue
- Proper
2. Specialised
Specialised connective tissue is ;
C-
Bl-
Bo-
Cartilage
Blood
Bone
Specialised connective tissue:
Cartilage is avascular and can be divided into 3 subgroups
H- (smooth, glassy appearance, tightly packed collagen fibres, found in the - tip)
E- ( flexible, collagen and elastic fibres ,light weight support found in the outer -)
F- (dense and tough, strongest collagen fibres, separates -)
Hyaline : nose tip
Elastic: outer ear
Fibrocartilage: separates vertebrae
Connective tissue proper:
What are the 4 categories of connective tissue?
- Lo? connective tissue
- D- connective tissue
- Re? tissue
- Ad? tissue
- Loose
- Dense
- Reticular
- Adipose
Connective tissue proper:
- Loose connective tissue : sub c- layer, permits s-
Cutaneous, stretch
Connective tissue proper:
- Dense connective tissue
There are 3 sub categories of dense connective tissue
- Dense regular c- (uni directional , very strong)
- Dense regular e- (permits stretch of organ)
- Dense i- (multidirectional, resistant to tension stress)
- Collagen
- Elastic
- Irregular
Connective tissue proper:
- Reticular tissue:
Reticular fibres s? other structures by providing a network for ly? vessels
Support
Lymphatic
Connective tissue proper:
- Adipose tissue:
L- , energy storage , insulation, protection , shock absorber
Lipids
