What is the main function of joints in the body?

.The human body consists of 206 bones in total. These bones are grouped into two main divisions - the axial skeleton and the appendicular skeleton. The skull is composed of two sets of bones, cranial and facial, that total to 22 bones.Each vertebra has a central hollow portion (neural canal) through which the spinal cord passes. The vertebral column is differentiated into cervical (7), thoracic (12), lumbar (5), sacral (1-fused) and coccygeal (1-fused) regions. Joints are essential for all types of movements involving the bony parts of the body. Locomotory movements are no exception to this. Force generated by the muscles is used to carry out movement through joints.
