The axial skeleton consists of the bones that make up the central axis of the body, including the skull, spine, ribcage, and sternum. The appendicular skeleton consists of the bones in the arms, legs, and pelvis.
The axial skeleton contains a total of 80 bones. The skull is made up of 22 bones, including the mandible (jawbone) and the auditory ossicles (tiny bones in the ear). The spine is made up of 26 bones, known as vertebrae, which are stacked on top of each other to form the spinal column. The ribcage is made up of 12 pairs of ribs, which are attached to the thoracic vertebrae in the back and the sternum in the front. The sternum, also known as the breastbone, is a flat bone that sits in the center of the chest.
The appendicular skeleton contains a total of 126 bones. The bones in the arms and legs make up the upper and lower limbs, respectively. The bones in the arms include the humerus (upper arm bone), radius and ulna (lower arm bones), and the carpals (wrist bones), metacarpals (hand bones), and phalanges (finger bones). The bones in the legs include the femur (thigh bone), tibia and fibula (lower leg bones), and the tarsals (ankle bones), metatarsals (foot bones), and phalanges (toe bones). The pelvis is made up of the ilium, ischium, and pubis bones, which are fused together to form the hip bones.
In total, the human body has 206 bones, with 80 in the axial skeleton and 126 in the appendicular skeleton. These bones play a vital role in supporting the body, protecting internal organs, and allowing for movement. They also serve as the body's primary source of minerals, such as calcium, which are necessary for maintaining strong and healthy bones.
