There are [B] 206 bones in humans. The human skeletal system consists of bones, cartilage, and ligaments that provide support, protection, and movement to the body. These 206 bones vary in size, shape, and function, ranging from tiny bones in the ear to large bones such as the femur (thigh bone). The axial skeleton, comprising the skull, vertebral column, and rib cage, forms the central axis of the body, while the appendicular skeleton consists of the bones of the limbs, shoulder girdle, and pelvic girdle.
Throughout life, bones undergo growth, remodeling, and repair processes. Some bones fuse together during development, reducing the total number from the original count at birth. Understanding the anatomy and physiology of the skeletal system is essential in various fields, including medicine, anthropology, and biomechanics, as it influences movement, posture, and overall body function.
