Week 3 Flashcards
White fat cells produce
Leptin, a polypeptide hormone
Fibrocartilage is composed of
hyaline cartilage and dense connective tissue.
What are the components of a triglyceride?
Glycerol and three fatty acid chains.
Numerous mitochondria are associated with which type of fat?
Brown
A major hormone that regulates the growth of cartilage is
Somatotropin
Which one of these is the main function of brown adipose tissue?
Thermogenesis
common condition with aging, in which the hyaline cartilage basically wears out.
Osteoarthritis
All the following statements about hyaline cartilage are true
-It is avascular
-In the adult, it is found mostly at articular surfaces of bone
-It lacks innervation
Chondrocytes are located in:
lacunae in hyaline cartilage.
Public symphysis has which type of cartilage?
Fibrocartilage
Intervertebral disc has which type of cartilage?
Fibrocartilage
Cartilage connecting ribs to sternum is:
Hyaline cartilage
Epiglottis has which type of cartilage?
Elastic cartilage
Meniscus of the knee has which type of cartilage?
Fibrocartilage
Cartilage of the hip joint (femur and pelvis) has which type of cartilage?
Hyaline cartilage
Tracheal rings have which type of cartilage?
Hyaline cartilage
External ear has which type of cartilage?
Elastic cartilage
Perichondrium covers the surface of hyaline cartilage except in this region.
Articular surfaces of joints.
The particles formed from ingested triglycerides, phospholipids, and cholesterol are called:
Chylomicrons
Which of these is a function of adipose tissue?
-Cushioning organs
-Insulation
-Thermogenesis
-Energy storage
Which type of lipoprotein is commonly called “bad cholesterol”?
Low-density lipoprotein
The type of adipose tissue that has adipocytes with a single lipid drop and a nucleus displaced to the plasma membrane is:
White adipose
Which type of protein fiber form the supporting framework of white adipose tissue?
Reticular fibers
The extracellular matrix of hyaline cartilage is composed in part of:
gel of proteoglycans and glycoproteins.
