Adipose and Cartilage

    Cards (42)

    • Reticular fibers form the supporting framework of white adipose tissue
    • Somatotropin is a major hormone that regulates the growth of cartilage
    • Hyaline cartilage lacks innervation, its avascular, and its found mostly at articular surfaces of bone
    • Perichondrium covers the surface of hyaline cartilage except articular surfaces of joints
    • Brown fat contain numerous mitochondria
    • Adipose tissue does thermogenesis, insulation, energy storage and cushioning organs
    • Low-density lipoprotein is known as bad cholesterol
    • White fat cells produce leptin, a polypeptide hormone
    • The particles formed from ingested triglycerides, phospholipids, and cholesterol are called chylomicrons
    • Main function of brown adipose tissue is thermogenesis
    • Triglyceride contains glycerol and three fatty acid chains
    • Hyaline cartilage can be found in tracheal rings, cartilage of hip joint, and cartilage connecting ribs to sternum
    • Elastic cartilage can be found in external ear and epiglottis
    • Fibrocartilage can be found in the intervertebral disc, pubic symphysis and the meniscus of the knee
    • Fibrocartilage is composed of hyaline cartilage and dense connective tissue.
    • Chondrocytes are located in lacunae in hyaline cartilage
    • White adipose has adipocytes with a single lipid drop and a nucleus displaced to the plasma membrane
    • The extracellular matrix of hyaline cartilage is composed in part of a gel of proteoglycans and glycoproteins.
    • Osteoarthritis is a common condition with aging, in which the hyaline cartilage basically wears out
    • Fibrocartilage has the highest concentration of fibroblasts associated with it
    • A benign fat cell tumor is called a lipoma
    • Hyaline cartilage has the largest amount of proteoglycans per unit mass
    • In routine histological sections, its not possible to see the lipid in the fat cells because the solvents used to prepare the slides dissolve the lipid
    • Triglycerides has the highest caloric content per gram
    • The extracellular matrix of cartilage (all three types) is composed of GAGs, proteoglycans, and collagen fibers, and elastic fibers.
    • All three types of cartilage form from mesenchyme.
    •  lipoprotein transports fat molecules and its composed of phospholipids, triglycerides, cholesterol, and other molecules.
    • Hydrolysis of VLDLs in the blood capillaries forms free fatty acids
    • Adipose is a loose connective tissue
    • Subcutaneous fat, under the skin, for thermoregulation
    • Visceral fat, for cushioning organs such as the heart, gonads, kidneys, intestines, etc
    • Brown adipose is located in Kidneys, adrenal glands, and a few other places
    • White adipocytes store lipids derived from dietary fats as chylomicrons, triglycerides as very-low-density lipoprotein and fatty acids
    • Lipids are released from adipocytes by the enzyme lipase, which is activated by the hormone norepinephrine from the adrenal gland
    • Chylomicrons (ULDLs) transport dietary lipids from the intestines to other locations in the body, where the triglycerides are broken down
    • Atherosclerosis is the buildup of fats, cholesterol and othersubstances in and on the artery walls
    • Cartilage resists compression because of the chemical bonds between type II collagen fibrils, hyaluranon (a type ofGAG), and proteoglycans
    • Fibrocartilage does not have a perichondrium
    • Hyaline cartilage allows low-friction joint motion, supports respiratory passages, connects ribs to sternum, and "controls" long bone growth at epiphyseal plates
    • Fibrocartilage is tough, resists strain, but cushions also
