What are immoveable joints?

Answer 1

Immovable joints are defined as joints in the skeleton that are not able to move. They are also known as synarthrotic joints and include synchondrosis, suture and gomphosis,
A joint that cannot move.

Answer 2

You have fibrous and cartilaginous types of joints that probably come under this category. Fibrous type of joints has got three categories. Suture, gomphosis and syndesmosis. There is almost no movement between your skull bones (Suture type). The same is true for joint between your teeth and teeth bearing bones (Gomphosis type). The same is true for the joint between lower end of tibia and fibula (Syndesmosis type). You have two types of joints that fall under the cartilaginous category. Primary and secondary cartilaginous joints. You have primary cartilaginous joint between the diaphysis and epiphysis of the long bone. This joint has got the least possible mobility of all joints, probably. The secondary cartilaginous joints are at pubic symphysis and inter vertebral disc. They have limited mobility. Movable versus immovable is a logical classification. But it is not a practical classification in 'Biology". The third class with less mobility or slight mobility should be there.

Answer 3

Your skull has fused immovable joints except for the lower jaw.
