The Intrinsic Back Muscles

muscles back

There are several different types of muscles in the back. These muscles are called intrinsic back muscles. The Intrinsic Back Muscles include the Latissimus dorsi, Transversospinalis, and Quadratus lumborum. Each of these muscles performs a different function. This article will explore these different muscle groups and help you learn which exercises target them. However, you should know that some of these muscles are not found in all people.

Intrinsic back muscles

The intrinsic back muscles are located on the lumbar area. They originate from the sacrum and insert onto the transverse processes of the vertebrae C1-C4. In addition to being a proprioceptive muscle, the intrinsic back muscles also exert downward pull on the ribs. When they are activated, they can resist upwards pull. These muscles include the splenius cervicis, levator costarum, and rectus abdominis.

The back muscles are divided into superficial, intermediate, and deep layers. The superficial layer is the most superficial layer of back muscles and the deepest is located deeper. These muscles act on the vertebral column, ribs, and upper limb. They are associated with different motion patterns. Some are involved in bending, extending, and rotating. This article will describe the anatomy of these back muscles in greater detail. Once you’ve become familiar with these muscles, you’ll be better prepared to exercise them.

Quadratus lumborum

One way to stretch your quadratus lumborum muscle is to sit on the floor. While seated, raise your right arm and lean your body to the left. Hold this stretch for 20-30 seconds. If you want to get a more intensive stretch, you can stand on your hands and spread your legs at least three feet apart. Then, bend forward at the hips as far as possible.

The QL is the deepest muscle in the back, connecting the lumbar spine to the hip. It stabilizes the lumbar spine, hikes the hip and aids in side bending. Because of its extensive function, many people experience pain associated with this muscle. Fortunately, simple exercises can provide relief and prevent further injury. You can also perform exercises aimed at strengthening your gluteus minimus and quadratus lumborum muscles.

Latissimus dorsi

The Latissimus Dorsi muscles are among the largest in the body. Injuries to this muscle can be extremely painful. While most lat pain will go away on its own with rest and home exercises, more severe cases may require medical attention. Fortunately, there are many effective exercises to stretch your lats and restore them to health. Listed below are a few effective stretches and strengthening exercises for your lats.

The Latissimus Dorsi muscle is located in the back and spans across the lower posterior trunk. It is responsible for the movement of the shoulder joint. It is the widest muscle in the body and belongs to the superficial back muscle group. Its back position makes it susceptible to injury. During exercises, you should ensure the correct positioning of your body and warm up your muscles throughout the body.


The transversospinalis muscles are located at the back of the human body. These muscles connect the transverse process of one vertebrae to the spinous process on the opposite side. Their action is similar to the actions of other muscles in the back. Specifically, transverse muscles extend the spine, while unilateral contractions rotate the vertebral column. To learn more about transversospinalis muscles, read Core Stability.

The semispinalis capitis muscle group attaches to the transverse processes of the thoracic and cervical spines. The splenius, a member of the same group, inserts on the spinous process of the occipital bone. They are vascularized from the posterior intercostal and occipital arteries. Because of their attachment to the skull, they play a unique role in articulating the head and neck. A bilateral contraction of the semispinalis muscle pulls the head and neck posteriorly, while a unilateral contraction causes the head to rotate and tilt to the occipital bone.
