Muscles in the Back

muscles in the back

The muscles in the back are divided into three groups. The first group is the intrinsic muscles, which sit under the skin. These muscles include the erector spinae and transversospinalis groups. Both of these groups go up and down the spine and on either side of the spinal column. The third group consists of the multifidus muscles, which lie on the lower back.

Arterial supply for the muscles in the back

The muscles in the back are provided with blood supply by several arteries located along the vertebral column. These muscles perform various functions including maintaining posture and producing movements in the spine. The muscles that originate from the spinal cord are called the deep back muscles. They are located in the lumbar region, especially on the spine.

The muscles in the back are grouped into four types: superficial, intermediate, and deep. The superficial back muscles are the rhomboid major and minor muscles. The deep cervical artery supplies the rhomboids and the levator scapulae. The lateral sacral artery provides blood supply to the muscles in the lumbar region.

Function of the muscles in the back

There are three major groups of muscles in the back: the superficial, intermediate, and deep. Each group has distinct functions, such as stabilizing the spine and mobilizing the trunk. Some of the muscles also have multiple functions. To better understand the functions of these muscles, let’s first look at the structure of the back.

The back contains approximately 40 different muscles and is divided into 20 muscle pairs. The function of these muscles varies from person to person, but the majority are involved in back movements. The largest back muscles are the serratus posterior superior and serratus posterior inferior, which are used for breathing. The rest of the back’s muscles are connected to the vertebrae, which are small bones located at each level of the back. Each vertebrae has a central part and small projections called spinous processes.

Common causes of tight back muscles

Tight back muscles can be a sign of a number of medical conditions. Many of these can be diagnosed with a physical exam. However, others may require a neuromuscular or neurological scan. In the case of spinal cord conditions, a medical professional may perform an immunohistochemical analysis of spinal fluid to check for proteins that cause excessive tightness. These tests also look for myofibroblasts, small connective tissue cells that increase the contractile force of the muscle tissue.

Tight back muscles can also be caused by overuse, trauma, or poor posture. Trauma can lead to pain, inflammation, or muscle spasms. In the case of a sudden injury, such as a fall, it’s important to seek medical treatment as soon as possible. Overuse, on the other hand, involves repeated, less severe stresses on the muscles over time. As a result, the muscles don’t have enough time to recover and become stiff.

Treatment options

Treatment options for muscles in the back vary from patient to patient and often depend on the specific cause of back pain. Some cases are acute, requiring immediate medical attention, while others may persist for up to 6 months. Your doctor will evaluate the cause of your back pain and make recommendations for treatment. He or she will check your range of motion, check for nerve problems, and press on different areas of your back to determine the source of your pain. He or she may also perform blood and urine tests to rule out other medical issues.

Imaging tests aren’t always necessary, and they are typically used to diagnose a tumor or fracture. In some cases, your healthcare provider may also use a myelogram to see if there is a bulging disc, or changes in the bones surrounding the spinal cord. During this test, a local anesthetic is injected into the low back and a dye is injected to show where the nerves and muscles are located.
