Lecture 8 Adipose & Cartilage (Connective Tissue II) Flashcards
What is adipose tissue?
defined by the abundance of adipocytes
What is adipose tissue derived from?
mesochyme
______ is specialized for energy storage as lipid, has droplets within triglycerides, and has high density energy storage form diet or liver
Adipose tissue
How can adipose tissue be mobilized?
lipases
What are the functions of adipose tissue?
White fat Energy storage Insulation Cushioning (around butt, and heart) Brown = thermogenesis, heat generation
True or False: Adipose tissue is well vascularized
True
_______ releases fatty acids and glycerol to mobilize
Hormone-sensitive lipase
mesenchymal cell gives rise to ______ which splits into a multilocular adipocyte (______) or into a unilocular adipocyte (______).
lipoblast, brown, white
______ adipose tissue is mitochondria-rich, nucleus is central and is slightly smaller.
Brown
Where does cartilage come from
chondrocytes
True or False: Cartilage is avascular
True
What is the function of cartilage?
Support soft tissue (respiratory tract)
Provides a cushioned low friction surface in joints
Where are fibro and elastic cartilage found?
fibro, intervertebral disc and pubic symphysis, elastic ear
What is the major proteoglycan and glycoprotein in articular cartilage?
Aggrecan, chondronectin
What is this image an example of? Name the parts
Hyaline cartilage (type II)
p = perichondrium (acidophilic)
c = chondrocytes
m = matrix
______ is an identical to hyaline cartilage but the only difference is ______ fibers.
elastic x2
______ is a mix of dense and hyaline cartilage, fewer proteoglycans, have type I present. picorsirus - hematoxylin
fibrocartilage
