30)what is joint discuss any two fibrous (immovable ) joints.

Dear student

Please refer the solution below for the said query

Points of contact between bones or between bones and cartilages is called joint. Joints act as fulcrum used to carry out movement by force generated through muscles.

Fibrous joints are the joints where bones fuse end to end with the help of dense fibrous connective tissues. They do not allow any movement. The two example are:
  1. Skull bones fuse end to end with the help of dense fibrous connective tissues called sutures to form cranium.
  2. A joint between the fibula and tibia at the ankle is a fibrous joint. 

Hope this information clears your doubt about the topic.

Regards
