Skeletal System Flashcards
most abundant and widely distributed tissues
Connective tissue
binds together, supports, and strengthens
protects and insulates internal organs
compartmentalizes structures
CONNECTIVE TISSUE
major transport system (blood)
CONNECTIVE TISSUE
primary location of stored energy reserves
main source of immune responses
CONNECTIVE TISSUE
secrete fibers and ground substance
Fibroblasts
develop from monocytes and destroy bacteria and cell debris by phagocytosis
Macrophages
secrete antibodies neutralize foreign substances
Plasma cells (plasmocytes)
produce histamine
Mast cells
fat cells, stores triglycerides (fats)
Adipocytes
Neutrophils, eosinophils, lymphocytes, monocytes, and basophils
Leukocytes (White blood cells)
-between the cells and fibers
-fluid, semifluid, gelatinous, or calcified
-medium for exchange of substances between the blood and cells
GROUND SUBSTANCE
Contains water and glycosaminoglycans (GAGs)
GROUND SUBSTANCE
viscous, slippery substance that binds cells together, lubricates joints, and helps maintain the shape of the eyeballs
Hyaluronic acid
provides support and adhesiveness in cartilage, bone, skin, and blood vessels
Chondroitin sulfate
skin, tendons, blood vessels, and heart valves
Dermatan sulfate
bone, cartilage, and the cornea
Keratan sulfate
GROUND SUBSTANCE
Hyaluronic acid
Chondroitin sulfate
Dermatan sulfate
Keratan sulfate
FIBERS (3)
Collagen fibers
Elastic fibers
Reticular fibers
-Consist of collagen
-pulling or stretching, not stiff, allows tissue
flexibility
Collagen fibers
consists of elastin molecules surrounded fibrillin
Elastic fibers
have the ability to return to their original shape after being stretched
Elasticity
-much thinner than collagen fibers and form branching networks
-consists of collagen
Reticular fibers
