- Fig. 1: Sagittal view of the cervical spine. (larger view). The cervical spine is comprised of seven vertebrae-C1, C2, C3, C4, C5, C6, C7 (often noted as C1-C7) - that begin at the base of the skull and extend down to the thoracic spine.he first cervical vertebra is unique in that it is a ring that rotates around the second vertebral body (the odontoid). The cervical vertebrae closest to the skull are the smallest. All of the cervical vertebrae are smaller than the vertebrae in the thoracic spine (upper back) and the lumbar spine (lower back).

- However, your feedback is important to us. The thoracic spinal vertebrae consist of 12 total vertebrae and are located between the cervical vertebrae (which begin at the base of the skull) and the lumbar spinal vertebrae. The second thoracic vertebra, or T2, is located directly below the first thoracic vertebra (T1).

- The vertebrae are the backbones. The cervical vertebrae are at the top. The skull rests on and turns on the first cervical vertebra, called C1. C1 is tied to the second cerv…ical vertebra, called C2, which allows, the head to turn far to each side by a special arrangement of bone and ligaments. C3, C4, and C5 are regular vertebrae, but smaller than those further down the spine.

Vertebrae of the Spine The transverse processes are located at right angles to the junction of pedicles and the lamina. They provide a place for the back muscles to attach to the spine. For the most part, these are absent in the vertebra of the neck (the cervical spine).

- Vertebrae: 33 vertebrae make up your spine. Column of ring-like bones. Also known as your backbone, your spine is a strong, flexible column of ring-like bones that runs from your skull to your pelvis. It holds your head and body upright and allows you to bend and twist your body.

Cervical Vertebrae Typical vertebrae have: 1  Vertebral body. This is a cylindrical-shaped, thick part at the front of the bony vertebra. 2  Vertebral arch. This bony arch wraps around the spinal cord toward the back and consists of two pedicles and two laminae. 3  Facet joints.

Cervical and Thoracic Spine Cervical Spine. This is your neck, which contains seven vertebrae(C1–C7). The last, C7 is the bone that generally sticks out the most. You can easily feel it at the base of your neck, especially when you bend your head forward. Go ahead, see if you can find it. The cervical vertebrae's main job is to support your head. This is no small feat given that the head can weigh as much as 11 pounds! That's why how you hold your head matters so much. For many computer workers, a small but constant forward jut of the head is not uncommon.

Understanding Spinal Anatomy: Regions of the Spine - Cervical, Thoracic, Lumbar, Sacral Thoracic Spine. Beneath the last cervical vertebra are the 12 vertebrae of the Thoracic Spine. These are abbreviated T1 through T12 (top to bottom). T1 is the smallest and T12 is the largest thoracic vertebra.

Sacral spine overview Sacral Spine. Sections. The sacral spine refers to the five fused vertebrae (S1-S5) at the end of the spinal column. Basically, the sacral spine is located behind the pelvis, between the hip bones and connects the spinal column to the pelvis. This general area is sometimes referred to as the lumbosacral spine.

What is the Spine? It consists of a stack of bones — 33 vertebrae, the sacrum, and the coccyx — and the intervertebral discs separating the bones. The spine is subdivided into regions known as the cervical, thoracic, and lumbar, with the pelvic region containing the sacrum and coccyx considered a separate entity.

Spinal anatomy Cervical spine (C1 to C7) — this is the upper or neck area of the spine, which is made up of the seven vertebrae at the top of the spine, which help support the head. Thoracic spine (T1 to T12) — the 12 vertebrae in the central section, to which the ribs are attached. Lumbar spine (L1 to L5) — the five vertebrae toward the lower back, which support much of the body’s weight. Sacrum (S1 to S5) — the five fused vertebrae located between the pelvic bones.

Seventh cervical vertebra Cervical vertebrae. In vertebrates, cervical vertebrae (singular: vertebra) are the vertebrae of the neck, immediately below the skull. Thoracic vertebrae in all mammalian species are those vertebrae that also carry a pair of ribs, and lie caudal to the cervical vertebrae.

X-rays of the Spine, Neck, or Back The spinal cord, a major part of the central nervous system, is located in the vertebral canal and reaches from the base of the skull to the upper part of the lower back. The spinal cord is surrounded by the bones of the spine and a sac containing cerebrospinal fluid.

Thoracic Vertebrae There are 12 thoracic vertebrae (denoted as T1-T12) found in adult humans, and they are situated in between the cervical and lumbar vertebrae, with a general sizing larger than the cervical but smaller than the lumbar vertebrae.

- The spine (also called the vertebral column or spinal column) is composed of a series of bones called vertebrae stacked one upon another. There are four regions of the spine: 1  cervical (neck). 2  thoracic (chest/trunk).3  lumbar (low back).he five lumbar vertebral bodies are the weight-bearing portion of the spine and are the largest in diameter compared to the thoracic and cervical vertebral bodies. They sit atop the sacrum, which is formed by five vertebrae fused together into a solid unit.

Definition The bones of spinal column are called vertebrae. Each vertebra has two wing-like protrusions, called a transverse process, that extend toward the sides. These protrusions provide an area for muscles and ligaments to attach to provide movement and flexibility in the back.

Anatomy of the Human Spine Vertebrae are the 33 individual bones that interlock with each other to form the spinal column. The vertebrae are numbered and divided into regions: cervical, thoracic, lumbar, sacrum, and coccyx (Fig. 2). Only the top 24 bones are moveable; the vertebrae of the sacrum and coccyx are fused.

Seventh cervical vertebra By convention, the cervical vertebrae are numbered, with the first one (C1) located closest to the skull and higher numbered vertebrae (C2-C7) proceeding away from the skull and down the spine. The general characteristics of the third through sixth cervical vertebrae are described here.

- Spine Anatomy Video. Vertebrae are the 33 individual, interlocking bones that form the spinal column. Each vertebra has three main functional components: the vertebral body for load-bearing, the vertebral arch to protect the spinal cord, and transverse processes for ligament attachment.
