Costovertebralis is a muscle located in the back of the human body, specifically in the thorax. It is one of the erector spinae muscles, which are a group of muscles that run along the spine and help maintain posture and stability. The costovertebralis muscle originates from the costal processes of the thoracic vertebrae and inserts into the transverse processes of the same vertebrae. Its primary function is to extend the spine, which helps in activities such as standing upright and maintaining an upright posture.

The costovertebralis muscle is innervated by the dorsal rami of the thoracic spinal nerves, which are branches of the spinal nerves that supply the muscles and skin of the back. This muscle is also supplied by the intercostal arteries, which are branches of the aorta that supply the intercostal muscles and the pleura.

The costovertebralis muscle is often involved in back pain and other musculoskeletal disorders. It can become strained or inflamed due to poor posture, repetitive movements, or trauma. Physical therapy, stretching exercises, and pain management techniques can help alleviate symptoms and promote healing.

In summary, the costovertebralis muscle is an important erector spinae muscle that plays a crucial role in maintaining posture and stability. Its innervation and blood supply are well-defined, and it is often involved in back pain and other musculoskeletal disorders. Understanding the anatomy and function of this muscle can help in the diagnosis and treatment of related conditions.
