18
Q

Causes adipocytes to uptake
glucose

A

insulin

19
Q

initiates _____
→ transforming non-carbohydrate into
glucose. → releases more energy through
lipolysis.

A

Norepinephrine; Gluconeogenesis

20
Q

Ketone bodies, Fats, Amino Acids.

A

Non-carbohydrate

21
Q

Hormone released by adipocytes.
Brain controls appetite.

A

leptin

22
Q

Several cavities containing fats

A

Mutilocular

23
Q

Why is it brown?

A

organelles are present in cytoplasm in brown adipose tissue and they are scattered especially in mitochondria

white adipose tissue - natutulak ng isa lipid globule yung nucleus

24
Q

Main function of brown adipocytes

A

Thermogenesis: Warm the blood.
Creation of heat. → iikot sa blood cells to
warm the blood

28
Q

Purpose of the perichondrium?

A

Layer that surrounds the cartilage

29
Q
  • Most common type of cartilage
  • Homogeneous and semitransparent
  • Located in the articular surfaces of movable joints, in
    the walls of larger respiratory passages (nose,
    larynx, trachea, bronchi), in the ventral ends of ribs,
    where they articulate with the sternum, and in the
    epiphyseal plates of long bones
A

Hyaline Cartilage

30
Q

What happens in Osteoarthritis

A

They regenerate poorly
Happens when thin hyaline cartilage
What happens in osteoarthritis: happens
kapag super thin na yung hyalin cartilage.
Cartilage acts as a lubricant para di
magkiskisan yung bones. Happens kapag
nagkiskisan na sila kasi manipis na hyalin
cartilage

31
Q
  • Fresh specimens are yellowish in color
  • Found in the auricle of the ear, the walls of the
    external auditory canals, the auditory (Eustachian)
    tubes, the epiglottis, and the upper respiratory tract.
A

Elastic Cartilage

32
Q

Mingling of hyaline cartilage and dense connective
tissue
* It is found in intervertebral discs, in attachments of certain ligaments, and the pubic symphysis—all places where it serves as very tough yet cushioning support tissue for bone.

A

Fibrocartilage

Serves as a reservoir of calcium, phosphate and
other ions.
