Detailed explanation-1: -The adult human skeleton usually consists of 206 named bones. These bones can be grouped in two divisions: axial skeleton and appendicular skeleton. The 80 bones of the axial skeleton form the vertical axis of the body.
Detailed explanation-2: -(1) Gliding joints move against each other on a single plane. Major gliding joints include the intervertebral joints and the bones of the wrists and ankles. (2) Hinge joints move on just one axis.
Detailed explanation-3: -The human body is a remarkable machine comprised of 270 bones at birth which later decreases to 206 due to fusion of some of our bones as we age. The joints connect bone to bone, and there are 360 joints in our bodies.
Detailed explanation-4: -The adult human skeletal system has a complex architecture that includes 206 named bones connected by cartilage, tendons, ligaments, and three types of joints: synarthroses (immovable) amphiarthroses (slightly movable) diarthroses (freely movable)
