|
composed of
|
fibroblasts, elastic fibers, collagenous fibers, ground substances
|
|
|
ground substance
|
can vary from fluid to solid. amporphous, gel-like, hydrophilic. secreted by fibroblasts
|
|
|
functions
|
support, storage, transport, protection, defense, healing
|
|
|
connective resident cell types (resident meaning stays in one area)
|
1. fibroblasts - most common cell type in CT. responsible for collagen production
2. macrophage - phagocytes that attacks and ingests foreign particles 3. mast cell - largest cell type. secretes heparin and histamin |
|
|
connective fiber types
|
1. collagen - most abundant. high levels in bone and dentin. flexible, high tensile strength. binds structures. not elastic
2. Elastic - less strength but more easily stretched. Branched, usually networks. (ex. arteries, vocal cords) 3. Reticular - thin, composed of collagen. mesh like and distensible (ex liver) |

CT classification
|
1. loose
2. adipose 3. dense 4. regular 5. irregular |
|
|
loose
|
inc cells, dec fiber (under epithelia). delicate membrane. space filler for muscles
|
|
|
adipose (another type of loose)
|
fat. loose CT. Protect, insulate, and store energy
|
|
|
dense
|
decreased cells, increased fibers. densely packed collagenous fibers, few fibroblasts. Strong cords. Poor blood supply so slow healing. Can be classified as regular or irregular. Bottom of 57 helpful
