  2. Spinal column - Wikipedia

    en.wikipedia.org/wiki/Spinal_column

    The upper cervical spine has a curve, convex forward, that begins at the axis (second cervical vertebra) at the apex of the odontoid process or dens and ends at the middle of the second thoracic vertebra; it is the least marked of all the curves. This inward curve is known as a lordotic curve. A thoracic spine X-ray of a 57-year-old male.

  3. Thoracic vertebrae - Wikipedia

    en.wikipedia.org/wiki/Thoracic_vertebrae

    The first thoracic vertebra has, on either side of the body, an entire articular facet for the head of the first rib, and a demi-facet for the upper half of the head of the second rib. The body is like that of a cervical vertebra, being broad, concave, and lipped on either side.

  4. Cervical vertebrae - Wikipedia

    en.wikipedia.org/wiki/Cervical_vertebrae

    In humans, cervical vertebrae are the smallest of the true vertebrae and can be readily distinguished from those of the thoracic or lumbar regions by the presence of a foramen (hole) in each transverse process, through which the vertebral artery, vertebral veins, and inferior cervical ganglion pass. The remainder of this article focuses upon ...

  5. Vertebra - Wikipedia

    en.wikipedia.org/wiki/Vertebra

    The anterior tubercle on the sixth cervical vertebra is called the carotid tubercle because it separates the carotid artery from the vertebral artery. There is a hook-shaped uncinate process on the side edges of the top surface of the bodies of the third to the seventh cervical vertebrae and of the first thoracic vertebra. Together with the ...

  6. Articular process - Wikipedia

    en.wikipedia.org/wiki/Articular_process

    The inferior processes or postzygapophysis project downward from a higher vertebra, and their articular surfaces are directed more or less forward and outward. The articular surfaces are coated with hyaline cartilage. In the cervical vertebral column, the articular processes collectively form the articular pillars. These are the bony surfaces ...

    Adopting a forward head and rounded shoulders posture places increased stress on the neck (cervical spine), mid-back (thoracic spine) and low back (lumbar spine), Dr. Halfman explains.

  8. Axial skeleton - Wikipedia

    en.wikipedia.org/wiki/Axial_skeleton

    The vertebral column consists of 5 parts. The most cranial (uppermost) part is made up by the cervical vertebrae (7), followed by thoracic vertebrae (12), lumbar (5), sacral (5) and coccygeal vertebrae (3–5). Cervical vertebrae make up the junction between the vertebral column and the cranium. Sacral and coccygeal vertebrae are fused and thus ...

  9. Spinal posture - Wikipedia

    en.wikipedia.org/wiki/Spinal_posture

    Looking directly at the front or back of the body, the 33 vertebrae in the spinal column should appear completely vertical. From a side view, the cervical (neck) region of the spine (C1–C7) is bent inward, the thoracic (upper back) region (T1–T12) bends outward, and the lumbar (lower back) region (L1–L5) bends inward.
