What are the 3 things you ask yourself when identifying connective tissue?Loose? Dense? or Fish Eyes?
IF IT’S NOT LOOSE, DENSE, OR CARTILAGE it's…Blood or Bone
LLLLots of ground substance, few fibersLoose CT
Many cell and fiber types. "All-around mix"Areolar CT
Branching Fibers with many cells. Fibers = branches Cells = leavesReticular CT
Big fat droplets w nucleus pushed aside Looks like marshmallowsAdipose CT
What tissue is all about the fibers?Dense
Fibers run in one direction Looks like long, straight hair Function: resist force in one direction (tendons, ligaments)Dense Regular
Fibers go in many directions Looks like raw meat Function: resist force in multiple directions (skin, joint capsules)Dense Irregular
Looks like a dead rubber band Function: stretch + recoil (aorta, some ligaments)Elastic Fibers
Chondrocytes in lacunae, fisheyesCartilage
"Hiding" fibersHyaline Cartilage CT
Some fibers visible Fibers look evenly distributed EEEEarsElastic Cartilage CT
Tons of fibers, more than cells Strongest cartilage "Fib(e)r Overload"Fibrocartilage Cartilage CT
RBCs: pink discs, no nucleus WBCs: larger, dark nucleus Platelets: tiny dotsBlood
Osteons look like tree rings Central canal in the middleOsseous
