Your skull has two sets of bones: Eight cranial bones and 14 facial bones. The cranial bones make up the top and back of your skull and support and protect your brain. The eight cranial bones include: 1. Two parietal bones (left and right). 2. Two temporal bones (left and right). 3. One frontal bone. 4. One occipital bone. 5. One ethmoid bone. 6. O...
The auditoryossicles (small bones) of your middle ear are the smallest bones in your body. These tiny bones transfer vibrations from your eardrum to your inner ear. The middle ear bones include: 1. Two malleus bones (one in each ear). 2. Two incus bones (one in each ear). 3. Two stapes bones (one in each ear).
The hyoid bone is a horseshoe-shaped bone that sits at the front of your neck. Muscles and ligamentshold it in place between your jaw bone and thyroid. Your hyoid bone helps you breathe, speak and swallow.
The vertebral column, or spine, includes 24 vertebrae plus your sacrum and your tailbone (coccyx). The vertebral column extends from the base of your skull to your pelvis. It’s grouped into five sections: 1. Seven cervical vertebrae: These bones form your neck and support your head. 2. 12 thoracic vertebrae: These bones form the rear anchor of your...
The thoracic cage, or ribcage, protects your heart, lungsand other organs. It attaches to muscles involved with breathing and arm movement. The bones in your ribcage include: 1. Sternum (breastbone): This is a long, flat bone that runs down the middle of your chest. 2. 24 ribs: Most people have 12 pairs of ribs.
Axial skeleton. 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.
What is the Axial Skeleton. The human skeleton is divided into two parts, with the axial skeleton being one of the two. The other one is the appendicular skeleton. There are 80 bones in the axial skeleton. As the name suggests, it includes the bones from the body’s vertical axis. Basic Functions of the Bones in the Axial Skeleton

The axial skeleton includes the bones that form the skull, laryngeal skeleton, vertebral column, and thoracic cage. The bones of the appendicular skeleton (the limbs and girdles) “append” to the axial skeleton. 1. Skull Bones Protect the Brain and Form an Entrance to the Body. The skull consists of the cranial bones and the facial skeleton.
The axial skeleton forms the longitudinal axis of the body, the center or midline of the body around which the limbs rotate, much as the earth spins around its center axis. Additionally, the axial skeleton supports the head, neck, and trunk, while providing rigid protection of the brain, spinal cord, and visceral organs in the thorax region.
