Connective Tissues Flashcards
The why of connective tissues
Fill internal spaces
support other tissues
transport materials
store lipids
Are they exposed to outside environments
No
They why
Fill internal spaces , supports other tissues , transport materials , store lipids
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
dense regular
dense irregular
elastic
Fibers run parallel, mostly collagen protein , tough ex. Tendons , ligaments
Dese regular
Fibers in random , fibers bundled in meshwork arrangement
Ex. dermis of the skin
dense irregular
made of mostly elastic protein fibers, somewhat parallel, branching arrangement
ex. elastic connections of vertebral spinous process
Elastic
What are the three types of loose connective tissue proper
areolar tissue
adipose tissue ( fat )
reticular tissue
Fills spaces between organs , surrounds/stabilizes/cushions organs
“packing material” of the body
( protection /seperation)
Loose connective tissue proper
Multiple types of protein fibers scattered
various cells scattered
found surrounding nerves, vessels, organs; between skin and underlying muscle
NOTHING TIGHTLY PACKED LOOSE ARRANGED
Areolar
Mostly fat cells ( adipocytes )
very little to no ground substance or protein fibers
Adipose
Each cell outlined by membrane
fat stored inside
used for cushioning/packing
Around the kidney for protection
Adipose
used to make the framework of delicate organs espy. those of the lymphatic system
( spleen, thymus ,lymph modes and bone marrow )
VERY DELICATE
Reticular
What are the two types of supporting connective tissue
Cartilage - semisolid matrix
Bone - solid matrix
Ground substance is a firm gel
Cartilage
cells suspended in this gel are called
Chondrocytes
What is cartilage tissue often surrounded by
Perichondrium
what are the 3 types of cartilage in the body
Hyaline
Elastic
Fibrocartilage
Smooth , tough , bright white like color , usually found @ the end of long bone
Hyaline
Provides support , tolerates distortion w/o damage and returns to original shape
Elastic
Resists compression; prevents bone - to-bone , contact; limits relative movement
( used in cartilage pads )
Fibrocartilage
What are the two types of fluid connective tissue
Blood and lymph
ground substance solid due to presence of calcium salts, main cell type called osteocytes , protein fiber mostly collagen
Bone
what are the two types of bone
Compact and spongy
- Ground substances mostly water with dissolved substances like protein , electrolytes , waste products ( plasma)
- Cells include red blood cels and white blood cells
Blood
Combination of epithelial and connective tissues
Membranes
What are the 4 varieties of membranes
Serous
Mucous
Synovial
Cutaneous
line internal body cavities ( not open to the outside environment )
Serous Membrane
Line passageways that are open to outside environment , secrete thick fluid
Mucous
Line joints spaces
Synovial
The skin
Cutaneous
