Joints are classified on the basis of:
Correct answer: D. Both Options A and C are correct
- A. The amount of movement allowed by them
- B. Type of bones they join
- C. Nature of structure they have
- D. Both Options A and C are correct
Explanation
Joints are indeed classified based on the nature of the structure they possess. The structural classification of joints is primarily based on the type of connective tissue that holds the bones together and the degree of movement allowed at the joint. There are two ways to classify joints: on the basis of their structure or on the basis of their function. The structural classification divides joints into fibrous, cartilaginous, and synovial joints depending on the material composing the joint and the presence or absence of a cavity in the joint.

About Support and Movement
Support and movement covers the axial and appendicular skeleton, bone structure, joints and the arrangement of skeletal muscles. Muscle contraction is explained through actin, myosin, sliding filaments, calcium ions and ATP, while arthritis is distinguished as a disorder of joints rather than a normal part of movement.
