How many bones are there in the head?
The bones of the head are mostly parts of the Cranium (Skull): Occipital Bone, Parietal Bones, Frontal Bone, Temporal Bones, Ethmoid, Sphenoid, Zygomatic Bones, Maxillae Lacrimal Bones, Nasal Bones, Inferior Nasal Conchae, Palantine Bones, and the Vomer. Also the Mandible (Jaw) and Hyoid. There are also 3 tiny bones in your middle ear, the Malleus, Incus, and Stapes. The trunk bones consist of the Vertebrae (spine): 7 Cervical, 12 Thoracic, 5 Lumbar, the Sacrum and the Coccyx. The 12 pairs of Ribs and the three bones of the Sternum: Xyphoid, Sternal Body and Manubrium.

What are the main parts of the vertebrae called?
The body of each vertebra is attached to a bony ring consisting of several parts. A bony projection on either side of the vertebral body called the pedicle supports the arch that protects the spinal canal. The laminae are the parts of the vertebrae that form the back of the bony arch that surrounds and covers the spinal canal. There is a transverse process on either side of the arch where some of the muscles of the spinal column attach to the vertebrae. The spinous process is the bony portion of the vertebral body that can be felt as a series of bumps in the center of a person's neck and back.

What bones protects spinal cord?
The spinal cord is protected by the vertebral column or spinal column. The vertebral column is a collection of individual bones called vertebrae that encase and protect the spinal cord. The vertebral column is divided into three parts: seven cervical (neck) vertebrae at the top, twelve thoracic vertebrae in the midback, and five lumbar vertebrae in the lower back. Below the lumbar vertebrae, but not protecting the spinal cord, are the sacrum and coccyx (tailbone).

What are the parts of the axial skeleton?
The axial skeleton has five parts:the skull (cranium and facial bones)the three auditory ossicles (hammer, anvil, stirrup in the middle ear)the hyoid bone in the neck(the only bone that does not articulate with another bone)the rib cage (the 24 ribs, and the sternum)the vertebral column (which includes 7 cervical vertebrae, 12 thoracic vertebrae, 5 lumbar vertebrae, 5 sacral bones, and 3 coccyx bones).The auditory ossicles and hyoid might be discounted as non-structural features.
