26
What are the three types of fibres in the Protein fibres of ECM?
Collagen, Elastic and reticular
27
What do ground substances consist of?
Water and organic molecules
28
What are the functions of ground substances?
Support cells and allow substances to be exchanged.
29
What can the structure of the ECM be?
Gelatinous, fluid, semifluid and calcified?
30
What are the functions of the ECM and what are they determined by?
Supports cells, binds cells, allows for exchange and stores water. By the structure.
31

bone to bone
32
what do tendons connect?
Muscle to bone
33
What is the structure of Areolar proper connective tissue?
Fibre- collagen, elatic and reticular cells0- fibroblasts, adipocytes, marcophages, mast cells, plasma cells and leukocytes
34
what is the function of Areolar connective proper cells?
Elasticity, support and strength
35
Where is Areolar connective proper?
Most connective tissues, anchors most epithelial
36
What is the structure of Adipose connective proper?
Adipose cells from fibroblasts Have fat droplets that pushes nucleus to cytoplasm
37
What is the function of Adipose connective proper?
insulation, energy source and protection of organs
38
where is Adipose connective proper found?
Fats and subcutaneous layer of the skin
39
What is the structure of reticular connective proper?
Fibres - reticular Cells - Reticular (fibroblast)
40
What is the function of reticular connective proper?
Provides support framework (stroma) Binds to smooth muscle and filters the blood in spleen
41
Where is reticular connective proper?
liver and spleen
42
What is the structure of regular connective proper?
Fibres layed in direction to give strength Cells - Fibroblasts Fibres - Collagen
