The muscles of the back can be arranged into 3 categories based on their location: superficial back muscles, intermediate back muscles and intrinsic back muscles.The intrinsic muscles are named as such because their embryological development begins in the back, oppose to the superficial and intermediate back muscles which develop elsewhere and are therefore classed as extrinsic muscles. The muscles of the back are a group of strong, paired muscles that lie on the posterior aspect of the trunk. They provide movements of the spine, stability to the trunk, as well as the coordination between the movements of the limbs and trunk. The back muscles are divided into two large groups:

Back anatomy What are your back muscles? Your back has many different muscles. Some muscles support your spine and trunk. Others help you move your body, stand up straight and assist with breathing. Because your back muscles support so much of your weight and are responsible for so many movements, injuries to these muscles are common. The deep back muscles, also called intrinsic or true back muscles, consist of four layers of muscles: superficial, intermediate, deep and deepest layers. These muscles lie on each side of the vertebral column, deep to the thoracolumbar fascia. They span the entire length of the vertebral column, extending from the cranium to the pelvis.

The muscles of the back categorize into three groups. The intrinsic or deep muscles are those muscles that fuse with the vertebral column. The second group is the superficial muscles, which help with shoulder and neck movements. The final group is the intermediate muscles, which help with the movement of the thoracic cage. Your back consists of a complex array of bones, discs, nerves, joints, and muscles. The muscles of your back support your spine, attach your pelvis and shoulders to your trunk, and provide mobility and stability to your trunk and spine. The anatomy of your back muscles can be complex. There are several different layers of muscles in your back. The back is found posteriorly and includes the vertebral column, the muscles that support the back and the spinal cord. The vertebral column consists of 33 vertebrae which can be split up into 5 continuous sections. Each section is functionally different and is specialised for either weight-bearing, movement, protection and/or posture.
