Lamina

By

Lamina The structure indicated is the lamina of the vertebra. The typical vertebra consists of the following features: Vertebral body Vertebral arch (neural arch) consisting of lamina and pedicle Spinous process Transverse process Vertebral foramen (collectively form vertebral canal) Superior and inferior articular processes Superior and inferior vertebral notches The vertebral arch is formed from two pedicles and two laminae. The pedicles attach on either side to the posterolateral aspects of the vertebral body and unite posteriorly with the laminae which complete the vertebral arch. The laminae provide attachment for the ligamentum flavum, which connect adjacent laminae along the length …

Spinous Process of Vertebra

By

Spinous Process of Vertebra The structure indicated is the spinous process of the vertebra. The typical vertebra consists of the following features: Vertebral body Vertebral arch (neural arch) consisting of lamina and pedicle Spinous process Transverse process Vertebral foramen (collectively form vertebral canal) Superior and inferior articular processes Superior and inferior vertebral notches The vertebral arch extends posteriorly from the vertebral body, comprised of two pedicles which extend from the posterolateral aspects of the vertebral body to join the two laminae on either side which complete the vertebral arch and enclose the vertebral foramen. Projecting posteriorly in the midline from …

Transverse Process of Vertebra

By

Transverse Process of Vertebra The structure indicated is the transverse process of the vertebra. The typical vertebra consists of the following features: Vertebral body Vertebral arch (neural arch) consisting of lamina and pedicle Spinous process Transverse process Vertebral foramen (collectively form vertebral canal) Superior and inferior articular processes Superior and inferior vertebral notches The transverse processes of the vertebrae extend from the vertebral arch at the point where the pedicles meet the lamina, and lie in between the superior and inferior articular processes. A facet on the transverse processes of the thoracic vertebrae serves as the point of articulation for …

Vertebral Body

By

Vertebral Body The structure indicated is the vertebral body. There are 33 vertebrae which make up the spinal column: 7 cervical 12 thoracic 5 lumbar 5 fused sacral vertebrae 3-4 fused coccygeal vertebrae The typical vertebra consists of the following features: Vertebral body Vertebral arch (neural arch) consisting of lamina and pedicle Spinous process Transverse process Vertebral foramen (collectively form vertebral canal) Superior and inferior articular processes Superior and inferior vertebral notches The vertebral body is the largest component of the vertebra. Between adjacent vertebrae within the spinal cord, the vertebral bodies are joined by intervertebral discs which form fibrocartilaginous …

Transverse Foramen

By

Transverse Foramen The structure indicated is the transverse foramen of a cervical vertebra. There are 33 vertebrae which make up the spinal column: 7 cervical 12 thoracic 5 lumbar 5 fused sacral vertebrae 3-4 fused coccygeal vertebrae The typical vertebra consists of the following features: Vertebral body Vertebral arch (neural arch) consisting of lamina and pedicle Spinous process Transverse process Vertebral foramen (collectively form vertebral canal) Superior and inferior articular processes Superior and inferior vertebral notches Transverse foramina are only present in the cervical vertebrae. These foramina allow the passage of the vertebral artery and vein. The vertebral arteries arise …
