Explanation: 

Detailed explanation-1: -Your axial skeleton is made up of the 80 bones within the central core of your body. This includes bones in your skull (cranial and facial bones ), ears, neck, back (vertebrae, sacrum and tailbone) and ribcage (sternum and ribs).

Detailed explanation-2: -Bones of the trunk: The 51 trunk bones consist of 26 vertebrae, 24 ribs, and the sternum. The 26 vertebrae comprise 7 cervical, 12 thoracic, and 5 lumbar vertebrae, plus the sacrum and the coccyx. The 24 ribs comprise 14 true ribs, 6 false ribs, and 4 floating ribs. The sternum is the breastbone.

Detailed explanation-3: -The axial skeleton is the part of the skeleton that consists of the bones of the head and trunk of a vertebrate. In the human skeleton, it consists of 80 bones and is composed of six parts; the skull (22 bones), also the ossicles of the middle ear, the hyoid bone, the rib cage, sternum and the vertebral column.

Detailed explanation-4: -The axial skeleton consists of the bones of the skull, the bones of the inner ear (known as ossicles), the hyoid bone in the throat, and the bones of the vertebral column, including the sacrum and coccyx bones in the center of the pelvic girdle.

Detailed explanation-5: -Flat Bones Protect Internal Organs There are flat bones in the skull (occipital, parietal, frontal, nasal, lacrimal, and vomer), the thoracic cage (sternum and ribs), and the pelvis (ilium, ischium, and pubis). The function of flat bones is to protect internal organs such as the brain, heart, and pelvic organs.
