What is an articulation?

1

Soft tissue in joints has no organic component.

1

Choose the FALSE statement about cartilage.

1

Choose the correct statements about cartilage histology.

1

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

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.

1

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

1

Hyaline cartilage remodels.

1

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

1

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

Choose the correct statements about ligaments and tendons.

Objectives: Describe the microanatomy of tissues in the joints and explain how their structure reflects their function. Define the three classes of joints and explain how their structure reflects their function.

A lateral ligament will restrict adduction.

When a tendon is pulled out it usually takes a section of bone with it.
