Connective Tissue Flashcards
Connective Tissue
diverse in structure and function
Ground Substance
noncellular material that seperates the cell
ex. bone, cartilage, blood
Collagen Fibers
– white
– contains collogen (protein that gives flexibility and strength)
Reticular Fibers
– very thin collogen fibers
– finely branched
– forms delicate supporting network
Elastic Fibers
– contains elastin
– can stretch to 100x their size without breaking
– provide flexibility
Loose Fibrous Tissue
– includes areolra and reticular connective tissue
– allows organs to expand
– forms protective coverings around many organs
Adipose Tissue
example of loose fibrous tissue
– made of adipocytes that store fat
– has little extracellular matrix
– fill with liquid fat for use as energy storage, insulation, and organ protection
Dense Fibrous Tissue
– contaons many collagen fibers packed together
– makes strong, flexible connections between tissues
Tendons
has dense fibrous tissue
– connects muscle to bone
Ligament
has dense fibrous tissue
– connects bone to bone
Cartilage
example of supportive connective tissue
– firm, whitish, flexible connective tissue
Hyaline Cartilage
– most common
– glassy, transparent
– in the nose, end of long bones, and ribs
– forms most of the fetal skeleton
Elastic Cartilage
– contains elastin fibers
– very flexible
– in outer ear
Fibrocartilage
– contains strong, collogen fibers
– found in structures that need to withstand pressure and tension like the disks between vertebrae and back of knee joint
Bone
– the most rigid connective tissue
– made of inorganic salts(containing calcium)
