Thoracic Spine Anatomy

The thoracic spine is the area between the neck and lower back that supports the chest. The thoracic spine is the second segment of the vertebral column located between the cervical and lumbar vertebrae.

T12 usually has larger pedicle diameter than l1.

Thoracic spine anatomy. Some of the thoracic spines most important roles include the following. Anchor the rib cage. The thoracic and sacral curves are kyphotic.

The spine has four natural curves that you can see in the above picture on the left. The muscles that affect the thoracic spines function include. By convention the human thoracic vertebrae are numbered t1t12.

Thoracic spine is kyphotic. Knowing the main parts of the thoracic spine and how these parts work is important as you learn to care for your back problem. The section of the spine found in the upper back is called the thoracic spine.

As part of the bony thorax the thoracic vertebrae help protect the internal viscera such as the heart lungs and oesophagus. It protects thoracic viscera such as heart lungs and great vessels. Thoracic spine anatomy the thoracic region consists of 12 vertebrae and is the largest segment of the spine.

T4 has the narrowest pedicle diameter on average t7 can be irregular and have a narrow diameter on the concave side in ais. A patients guide to thoracic spine anatomy introduction. Pedicle diameter the pedicle wall is twice as thick medially as laterally.

Another long muscle this one travels up the spine from the middle of the lumbar spine. It consists of twelve vertebrae which are separated by fibrocartilaginous intervertebral discs. Due to its articulations with rib cage the thoracic spine is more rigid than the cervical and lumbar regions.

It goes from the base of the neck to the bottom of the rib cage. The rib cage supported by the thoracic spine in the back. They are distinguished by the presence of facets on the sides of the bodies for articulation with the heads of the ribs as well as facets on the transverse processes of all except the eleventh and twelfth for articulation with the tubercles of the ribs.

The shape of the thoracic vertebrae is similar to those in the anatomy of the lumbar spine but reduced in size. Protect the spinal cord. This long muscle moves the spine and helps with posture.

Again just like its neighbors above and below the disc in front separates the two vertebral bodies and the facets in back guide the motion of the spine. Two are lordotic and two are kyphotic. The thoracic spine is the second spinal region.

The spinal cord is a critical bundle of nerves. The cervical and lumbar curves are lordotic.
