Thoracic Spine - Definition & Components - Human Anatomy | Kenhub

The thoracic vertebrae are located in the middle section of the vertebal column, inferior to the cervical and superior to the lumbar vertebrae.

The vertebrae are separated by intervertebral discs of fibrocartilage, which are flexible cartilage discs located between the bodies of two adjacent vertebrae that allow movement in the spine and have a shock absorbing or cushioning function as well.

Distinguishing features of the thoracic vertebrae include the presence of costal facets on the sides of the bodies for articulation with the heads of the ribs, and facets on the transverse processes of all, except the 11th and 12th vertebrae, for articulation with the tubercles of the ribs. In addition, the spinous processes are relatively more pointed than other vertebrae, and angle sharply downward.

In this video we will go over the features of the thoracic vertebral column and its components, the thoracic vertebrae.

At first sight the study of human anatomy seems to bo complex and overwhelming. It is tru?e that it's complex and your studies will not alter that. As for being overwhelming, that can be eleviated if you take it one step at a time. I found an article on Sebs Study Crammer very useful for this.

Your voice will benefit from doing some deep breathing and vocal warmups before your recording. Your voice sounds strained and rises into your head at points. Focus on speaking on your breath and take a couple steps back from ur mic if u need to.
