Q

Three types of cartilage:

A
  • hyaline (most abundant and basic, aka glass cartilage) nose and trachea
  • elastic (+elastic fiber, recoil) ear & epiglottis

Q

The organic material in bone is

A

Collagen (~35%) which gives pliability

17
Q

Compact vs Woven bone

A

Compact - around periphery/outside of the bone, solid strong.
Woven - spongy bone (majority of bone), more space reduces weight

18
Q

Bone marrow is in the

A

Medullary cavity (middle)

19
Q

Shaft of long bone aka

A

Diaphysis

20
Q

Each end of a long bone is called

A

Epiphysis (proximal/distal)

21
Q

Two types of bone marrow

A

Red marrow - actively producing blood
Yellow marrow - dormant (has adipose)

22
Q

Hyaline cartilage found on the ends of a long bone is called:

A

Articular cartilage

23
Q

T/F Bone is a solid structure that is constantly rearranging (around vasculature)

A

True

24
Q

Osteon are

A

Cylindrical structures, blood supply in the central canal, surrounded by rings of tissue.

25
Q

Lacunae

A

Pockets in bone where osteocytes were sitting

26
Q

How many named bones in human body

A

206

27
Q

Bones (organ) provide:

A
  • support and movement
  • protection of underlying organs
  • mineral storage (calcium phosphate)
  • blood cell formation (red/yellow marrow
28
Q

Hyaline cartilage

A
  • most abundant
  • support through flexibility
  • glass cartilage
  • nose and trachea
29
Q

Elastic cartilage

A
  • contains many elastic fibers
  • able to tolerate repeated bending
  • ears and epiglottis
30
Q

Fibrocartilage

A
  • resists strong compression and tension
  • intermediate between hyaline & elastic
  • padding between joints and spine
