7 Cervical Bones
12 Thoracic Bones
5 Lumbar Bones
5 Sacrum Bones
4 Coccyx Bones
The skull protects the brain, the rib cage shields the heart and lungs, and the vertebrae safeguard the spinal cord.
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.
You have 7 unfused cervical vertebrae. You have 12 unfused thoracic vertebrae. You have 5 unfused lumber vertebrae. The five vetebrae are fused in case of the sacrum. That is the need of the hour. You can not support the hip bones with out that fusion. Then there are few fused vertebrae in coccyx.
Firstly, the spine is separated into three separate types of vertebrae: the first seven starting at the base of the skull are the cervical vertebrae (and the first specifically being the atlas and second the axis), the next twelve are the thoracic vertebrae, and the last five are the lumbar vertebrae. The spine ends with the large sacrum bone and then ends with the coccyx (tailbone). between these vertebrae are disks of hyaline cartilage. The vertebral column houses the spinal cord. The spinal cord branches out between each vertebrae with nerves that lead to different areas of the body.
usually located in the back part of the spine
The 33 ring-shaped bones of the spine are called the vertebrae.
The small parts that make up your spine are called vertebrae. The vertebrae are the individual bones that stack together to form the spinal column
Possums have a skeleton which hold the bones of its body together. The bones begin at the skull forming a protective cover and form parts of the vertebrae, the pelvis and the spiny tail.
The skull protects the brain, the rib cage shields the heart and lungs, and the vertebrae safeguard the 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).
The vertebrae
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.
The bony segments of the spine is the vertebrae.
There is cartilage in backbone and between the parts of the vertebrae of the backbone but the bone itself is actually an organ that produces blood like all other bones do.
The ribs articulate with the thoracic vertebrae. The thoracic vertebrae also articulate with each other.
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.
Down parts of the centerline of the back there should be some pronounced bumps. These are the spineous processes of the vertebrae. They are no visible on everyone due do a difference in muscle and/or fat levels.
