Question

Which joint joins a bone with a joint capsule.
A) Immovable joint
B) Slightly movable joint
C) Synovial joint
D) None of the above

Answer 1

Hint: Joints are the connections between the two bones. These joints link bones together and form the skeletal system. These joints are constructed differently so as to help in the different kinds of movement.

Complete answer:
There are 360 joints in our body. The joints are cushioned with cartilage or fibrous tissue so that the movement along the joints can be smooth and easy. The joints have synovial fluid which acts as a lubricant.

Let us discuss the types of joints given in the question:
A) Immovable joint- These kinds of joints connect the bone ends by a fibrous tissue. These kinds of joints are found in the bones of the skull, sockets in the mandible and maxilla.
B) Slightly movable joint- It is also known as amphiarthrosis. In this, the articulation in the bones allows limited movement. The limited movement is due to the fibrous tissue or cartilage. E.g.- Vertebrae of the spine.
C) Synovial joint- It is the most found joint in our body. In the case of a synovial joint, the joint joins the bones by the fibrous joint capsule. The joint is characterised by the fluid-filled joint cavity which is present in a fibrous capsule. The articulation within the fibrous capsule makes it a strong joint. This joint is present in the ball and socket joint, hinge joint present in the knee, shoulder etc.

Thus the correct answer is option ‘C’.

Note: The joints present in the fingers, hips, elbows, toes, hips are the movable joint which is present in most of the parts of the body. The surfaces are lined by smooth cartilage which reduces friction.
