8 Cards in this Set
- Front
- Back
|
EMBRYONIC
Mesenchyme or Mesenchymal CT |
-contains mesenchymal cells w/ high mitotic activity
-no CT fibers -abundant ground substance |
|
|
Mucous or Gelatinous CT
|
-stellate fibroblasts
-viscous gel-like ground substance -few fibers |
|
|
ADULT
Loose Irregular CT or Areolar Tissue |
-widely distributed
-random arrangement of fibers (all fibers) -wide spaces -ground substance has proteoglycans -location: beneath epithelia around nerve, skeletal muscle -Funcitons: mechanical support, nutritional supply, tissue repair, defence mechanisms |
|
|
Dense Irregular CT
|
-more abundant fibers than cells
-collagen fiber bundles cross -resist strecthing in all directions -elastic fibers for bounce back Location: -aponeurosis of muscles, fascia, joint capsules, capsule of organs, dermis |
|
|
Dense Regular CT
(Tendons and Ligaments) |
-run parallel
-ligaments have less ground substance than tendons -fibers oriented in a regular pattern -great tensile strength endotendineum peritendineum epitendineum |
|
|
Elastic CT
|
-predominance of elastic fibers
-each fiber surrounded by loose CT -where you need lots of flexibility |
|
|
Reticular CT
|
-reticular fibers form 3D network
-location: stroma of lymphatic organs and bone marrow |
|
|
Adipose Tissue
|
-intracellular lipid synthesized from fatty acids, carbohydrates, proteins
-enzymic hydrolysis of lipid by hormonal control (insulin) or neural control (norepinephrine) -in brown: mitochondrial respiration is uncoupled from ATP synthesis so produce heat -functions: thermal, mechanical insulation, metabolic function, dampening cushion, heat energy -White: intercellular spaces contain collagen and reticular fibers and dense capillary network -Brown: contain fibrocytes, collagen and reticular fibers and dense capillary network |
