Connective Tissues Flashcards
Types of loose connective tissue
Areolar connective tissue, reticular connective, adipose connective tissue (ARA)
Types of Cartilage
Fibrocartilage, hyaline cartilage, elastic cartilage

Brown vs. White Adipose Tissue
1) Brown - found mostly in infants , dark, more vascular, higher number of mitochondria 2) white - found mostly in adults, less vascular
Types of connective tissue fibers
1) Collagen fibers 2) Elastic Fibers 3) Reticular fibers
Collagen Fibers
relatively thick, thread-like composed of collagen and occur in long, parallel bundles. can withstand force along long axis
Elastic Fibers
Thinner and form complex networks; branched; return back to normal length after stretch
Reticular Fibers
Highly branched and delicate support networks. Able to resist forces applied from many different directions.
Fixed Cells
Fibroblasts, adipocytes, fixed macrophages, mesenchymal cells, and melanocytes
Wandering Cells
Free macrophages (in blood monocytes), mast cells, lymphocytes, microphages (neutrophils and eosinophils migrate throughout the body and respond to chemicals released by macrophages and mast cells. Also phagocytic)
