Explanation

Question 2 of 9

1

Bone is made of the basic tissue known as tissue. There are two extracellular components: .
The component (1/3 of ECM) is mainly fibres to resist , in a base of proteoglycans which hold water volume.
The component (2/3 of ECM) is what makes bone hard. It contains , which resists .

Question 3 of 9

1

Which statement about the cellular components of bone is FALSE?

Select one of the following:

  • Osteoblasts destroy bone.

  • Osteoblasts become osteocytes.

  • Osteoclasts break down the ECM.

Explanation

Question 4 of 9

1

Choose the statements about the structure of compact bone which are correct.

Select one or more of the following:

  • The outer layer of compact bone (the periosteum) has holes in it.

  • It is made up of osteons, which are longitudinal cylinders made of lamellae.

  • Lamellae are the tubes of ECM, with collagen fibres aligned parallel to direction of growth.

  • There are no nerves, arteries, or veins in the compact bone.

  • The osteons maintain the osteocytes by providing them with nutrition.

Explanation
