Connective Tissue Flashcards
Connects body parts.
Protect. Support. Bind
Connective Tissue
What are the characteristics of connective tissues?
- Variation in blood supply (vascularized, avascular)
- Extracellular matrix (nonliving material outside cell)
What are 2 elements of the extracellular matrix?
- Ground substance (water, glycoproteins, polysaccharide molecules)
- Fibers (collagen, elastic, reticular)
Connective tissue from most rigid to softest
- Bone
- Cartilage
- Dense connective tissue
- Loose connective tissue
- Blood
Has osteocytes in lacunae.
Calcium salts.
More collagen fibers.
Protect. Support
Bone
Less hard, more flexible than bone.
Chondrocyte - major cell type
Cartilage
Collagen fibers. Fibroblasts.
Tendons. Ligaments. Dermis.
Dense connective tissue
Muscle to bone connection
Tendon
Bone to bone connection
Ligament
More cells, softer, excluding blood.
Loose connective tissue
Widely distributed cobwebs. Universal packing tissue/glue.
Areolar connective tissue
Areolar connective tissue. Adipose (fat) cell dominated.
Insulation. Protection. Energy Storage.
Adipose connective tissue
Interwoven reticular cells.
Stroma (internal organ framework)
Lymph nodes, spleen, bone marrow
Reticular connective tissue
Blood cells surrounded by blood plasma.
Soluble fibers only visible during clotting.
Transportation of cardiovascular system in nutrients, wastes, respiratory gases.
Vascular Tissue (blood)
