Explanation / Answer

1) - c hemiarthrosis . As classification of joints according to.

movements include only three-day syn, amphi and di arthrosis

2) d- diarthrosis- this is a freely movable type of joints. Three types uni , bi and multiaxial.

3) d- inner synovial layer and outer fibrous capsule.

4)C- hyaline cartilage line the bones of synovial joints that are present in diarthrosis

5) d) all of them , primarily it reduces friction and acts as shock absorber but also provides nutrients to condrocytes.

6) a- fat pads

7) b - sprain

8) a- flexion

9) C- abduction

10)d - nuclues pulpus and annulus fibrosus

11) c anterior cruciate ligament as it may require surgery.
