What is the anatomy of the vertebrae?

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 causes a Hemivertebrae?

Hemivertebrae, or wedge-shaped vertebrae, are caused by failure of formation or segmentation of somites during osteogenesis. One probable cause of this failure is a lack of blood supply to the vertebrae.

What are the 7 process of vertebrae?

There are seven cervical vertebrae (but eight cervical spinal nerves), designated C1 through C7. These bones are, in general, small and delicate. Their spinous processes are short (with the exception of C2 and C7, which have palpable spinous processes). C1 is also called the atlas, and C2 is also called the axis.

How common is Hemivertebrae?

Hemivertebra is a congenital (present from birth) anomaly of the spine in which only one half of the vertebral body develops. It occurs in about 3 in 10,000 births. It is a common cause of congenital scoliosis where the spine is curved sideways.

What are the Corpos vertebrais and discos intervertebrais conectados?

Os corpos vertebrais das vértebras cervicais também estão conectados pelas articulações uncovertebrais (fendas de Luschka). Os corpos vertebrais e os discos intervertebrais são reforçados por dois ligamentos longitudinais fibrosos.

What is Arco vertebral?

Arco vertebral – a estrutura localizada posteriormente ao corpo. Consiste em dois pedículos e duas lâminas. Os pedículos contêm incisuras vertebrais (superiores, inferiores) que formam o forame intervertebral. Este permite a passagem dos nervos espinhais que saem da medula espinhal.

What are vertebral anomalies?

Vertebral anomalies. The vertebral column is affected by a range of anatomical variants of the body and/or neural arch as well as accessory ossicles. Knowledge of basic vertebral anatomy and ossification is essential for describing and understanding the range of anomalies.

What is a Coluna vertebral?

A coluna vertebral (coluna espinhal ou espinha dorsal) é uma estrutura curva composta por vértebras ósseas que são conectadas através de discos intervertebrais cartilaginosos. Faz parte do esqueleto axial e se estende desde a base do crânio até a ponta do cóccix.
