Joints between bones of sternum

Question 19

What is synovial joint composed of & mobility

Answer 19

Freely mobile
1 Space between bones
2 articularsurfaces
3 fibrous capsule
4 synovial membrane
5 synovial fluid

Question 20

Describe the structure of synovial joint

Answer 20

The two articular surfaces are covered with hyaline cartilage
They are then connected / surrounded by a fibrous capsule whose inner surface is covered with synovial membrane which also covers the non articular part of the bone inside the joint and the synovial membrane secrets and absorbs the synovial fluid which : act as a lubricant , provides nutrient to the articular cartilage and structures inside the joint and it allows free movement ofthe joint
