T or F contains more extracellular materials than epithelia
true
T or F exposed to the outside environment
false
Most connective tissues have extracellular protein fibers ( strands )
Yes
The cells and proteins are immersed in a substance produced by the cells themselves
Yes this is called ground substance
How many types of connective tissues are there and what are there names
Connective tissue proper
supporting connective tissue
fluid connective tissue
What are the two types of connective tissue proper
Loose connective tissue
Dense connective tissue
Fewer fibers , more ground substance “squishy”, pliable , cushiony
Ground substance - thick , syrupy , gooey , semi-fluid ( like molasses)
Loose tissues
Mostly protein fibers , less ground substance, loose packed together
Dense connective tissue
Connect other tissues together , protect organs , store lipids
Connective tissue proper
Provide structural support of the body
Bone and cartilage
supporting connective tissue
Transport substances around the body , blood and lymph
Fluid connective tissue
Where are connective tissue proper found around the body
around blood vessels , around nerves , on top of and around the abdominal organs , between skin and muscle cells etc .
what are some connective tissue proper cell types
Fibroblast - fiber building
Macrophages
Mast cells
leukocytes - w/ blood cells
Connective tissue proper protein fibers
Collagen - strong
Elastic - thin and stretchy
Reticular - thin , treadlike , delicate, break if pulled
What are the 3 types of desert connective tissue proper
