A skeleton is the internal framework of the human body that provides shape, support, and protection to vital organs. It is made up of bones connected by joints, and it plays a key role in movement and posture. The study of the skeleton comes under Anatomy. The human skeleton consists of 206 bones in an adult, including the skull, spine, ribs, and limbs. Important parts include the Skull, which protects the brain, the Vertebral Column, which supports the body, and the Rib Cage, which protects the heart and lungs. Besides protection, the skeleton also helps in movement by working together with muscles and joints. It produces blood cells in the bone marrow and stores essential minerals like calcium and phosphorus. The skeleton is an essential system of the body, making it a fundamental topic in science education and medical studies.
