L8 Structures Involved in Joints

Question 1 of 14

1

What is an articulation?

Select one of the following:

  • Where two bones meet at a joint.

  • A pivot point.

  • Cartilaginous ends moving against each other.

Explanation

Question 2 of 14

1

Soft tissue in joints has no organic component.

Select one of the following:

  • True
  • False

Explanation

Question 3 of 14

1

Choose the FALSE statement about cartilage.

Select one of the following:

  • Cartilage is soft tissue.

  • Hyaline cartilage is the same as articular cartilage.

  • Fibrocartilage is what the epiphyseal plate is made from.

  • Fibrocartilage has a different histological structure from hyaline cartilage.

Explanation

Question 4 of 14

1

Choose the correct statements about cartilage histology.

Select one or more of the following:

  • The chondrocytes live in lacunae.

  • Cartilage is composed mainly of collagen fibres.

  • Cartilage is white due to fatty acids.

  • Cartilage acquires nutrients via diffusion as it is not vascular.

Explanation

Question 5 of 14

1

Diffusion of nutrients into cartilage is achieved via 'loading', regular joint movement/activity

Select one of the following:

  • True
  • False

Explanation

Question 6 of 14

1

Hyaline cartilage is , with collagen content, and a water content, that resists
Fibrocartilage has bundles of collagen, and resists The orientation of these fibres are aligned in the direction of stress and so it also resists , making it specialised.

Explanation

Question 7 of 14

1

Lack of bony congruence is made up for by hyaline cartilage moulding to the articulations of synovial joints.

Select one of the following:

  • True
  • False

Explanation

Question 8 of 14

1

Hyaline cartilage remodels.

Select one of the following:

  • True
  • False

Explanation

Question 9 of 14

1

The more bony congruence there is, the more soft tissue support is needed.

Select one of the following:

  • True
  • False

Explanation

Question 10 of 14

1

The menisci are convexly shaped and diffuse forces through the bones of the knee.

Select one of the following:

  • True
  • False

Explanation

Question 11 of 14

1

Choose the incorrect statement.

Select one of the following:

  • Intervertebral discs are made of fibrocartilage.

  • The nucleus pulposus is a gel like structure which resists compression, and is distributed over the top of the intervertebral disc.

  • "Slipping a disk" is a tear in the fibrocartilage of the intervertebral disc where the nucleus pulposus has been removed from the proper position.

Explanation

Question 12 of 14

1

Choose the correct statements about ligaments and tendons.

Select one or more of the following:

  • They are composed of DFCT.

  • They have low collagen content.

  • They are slightly vascularised.

  • They are maintained by fibroblasts.

  • Ligaments join muscle to bone at an insertion, facilitating movement.

  • Tendons join bone to bone, restricting unwanted movement.

Explanation

Question 13 of 14

1

Select one of the following:

  • True
  • False

Explanation

Question 14 of 14
