|
identify the 3 types of CT and how they are deermined |
proper, supporting and fluid determined by their physical properties |
|
|
identify the functions of CT |
connection - tendons/ligaments support - bones/cartilage protection - capsules separation - sheath cushioning/insulation - adipose tissue transport - blood |
|
|
all CT originates from ___ |
embryonic mesenchyme
|
|
|
identify the 2 components of the ECM |
protein fibers ground substance |
|
|
identify the specialised cells found in CT |
adipocytes mastocytes phagocytes leukocytes lymphocytes |
|
|
identify and describe the 3 types of protein fibres in the ECM |
collagen fibres - type I - tendons/ligaments, type II - cartilage, type III - reticular fibres, formed from fibroblasts+3 aa chains elastic fibres - long and thin, secreted by fribroblasts, form branching network reticular fibres - spider web, type III collagen (lver, spleen, lymph |
|
|
what component/s of the ECM will influence it's viscosity? |
the GAG content of the proteoglycans, the higher the content, the greater viscosity and lower compressibility - good for joints |
|

which type of CT proper offers strength and support |
loose areolar |
|
|
which type of CT proper is found in the dermis |
dense, irregular collagenous |
|
|
what is the cause of marfan's Syndrome |
abnormal fibrillin 1 production leading to defective elastic fibres |
|
|
which CT disorder is characterised by inflammation of CT |
