Answer:
Arthroplasty
Explanation:
The restoration of function of a joint is called Arthroplasty. The bone functions are restored by maintaining the bones through resurfacing. Some times artificial joints are also used instead of resurfacing the existing bones.
Arthroplasty is a method to cure Osteoarthritis, or degenerative joint disease where joint cartilages reduces with age.
Also when medical treatments no longer make any impact on the joints of bone pain then Arthroplasty is done.
The more numbers of the homologous structure, the more likely they have recently shared a common ancestor.
Explanation:
Homologous organs are defined as those organs which do have different functions but a similar basic structure which denotes the divergent evolution. Homologous organs are seen in species that are very close to each other which are more related with each other in terms of evolution. For example, a bird is more close to each man than a fish, so do share more homologous organs common to man than fishes do. Examples of the homologous organs are hands of human and wings of birds. They have same basic structure like skeletal structure which is humerus, radius, ulna, carpals, metacarpals and phalanges. They are similar in structure but have different functions like flying in birds and gathering food in humans.
