Does the spine have 26 bones?
The spine, also known as the vertebral column or spinal column, is a column of 26 bones in an adult body — 24 separate vertebrae interspaced with cartilage, and then additionally the sacrum and coccyx.
Does the spinal cord have bones?
The spinal cord lies inside the spinal column, which is made up of 33 bones called vertebrae. Five vertebrae are fused together to form the sacrum (part of the pelvis), and four small vertebrae are fused together to form the coccyx (tailbone).
What are the 33 vertebrae?
Vertebral Column and Spinal Cord The vertebral column (VC) is composed of 33 vertebrae [cervical (C), 7; thoracic (T), 5; lumbar (L), 5; sacral (S), 5; coccygeal, 4], which are interconnected by intervertebral (IV) disks (except C1, C2) and stabilized by spinal ligaments.
What is the smallest bone called?
stapes
The 3 smallest bones in the human body–malleus, incus, and stapes–are located in the middle ear. At 3 x 5 mm in size, the stapes is the smallest bone in the human body. All 3 bones are essential for hearing.
How are bones in the spine?
The spine is composed of 33 bones, called vertebrae, divided into five sections: the cervical, thoracic, and lumbar spine sections, and the sacrum and coccyx bones. The cervical section of the spine is made up of the top seven vertebrae in the spine, C1 to C7, and is connected to the base of the skull.
What does T10 vertebrae control?
What is the T10 Vertebra? Also called the tenth thoracic vertebra, T10 is one of the twelve vertebrae of the thoracic spinal column. The nerves that control the muscles of the lower abdomen originate through here.
What is the Atlas bone?
The Atlas: The Top Bone in Your Cervical Spine The occipital bone rests upon the atlas, the first bone in your neck. The atlas is named after the Greek God Atlas, who held up the world on his shoulders. A pair of synovial joints, known as the atlanto-occipital joint connect the atlas and your skull.
The spine has 26 bones which are like circles with wings on the sides and back. They are called the vertebrae (say ver-tu-bray). There are small discs made of cartilage between each vertebra. They act like shock absorbers and also stop the bones rubbing against each other.
How many bones are in a human spine?

How many spinal nerves are there total in the body?
Spinal nerve, in vertebrates, any one of many paired peripheral nerves that arise from the spinal cord. In humans there are 31 pairs: 8 cervical, 12 thoracic, 5 lumbar, 5 sacral, and 1 coccygeal. Each pair connects the spinal cord with a specific region of the body. Near the spinal cord each spinal nerve branches into two roots.
