Spinal anatomy: Muscle anatomy of the back

The main goal of your spine is to sustain your body weight and protect the spinal cord from injury. Your columns also have specific objectives; It is used to carry messages from the brain to the nerves and then nerves throughout your body. Because these nerves affect all types of body parts, when the spine is damaged, it can have a dramatic effect on your daily life.

A healthy column is a powerful and flexible column that lets you move in a variety of ways. The spine consists of many different structures that should work together to avoid the effects of stress, tension, injury, or illness.

Spinal curve
A healthy bone starts with the shape of C and when you start growing and learning to walk with two legs instead of crawling, your spine adapts to changing its shape. As adults, the spine has a natural S. form. In an upright position, your body weight constantly pushes the spine forward. This S-shaped curve is held by the muscles on your back. Therefore, when you have a weak back muscle, your posture is usually wrong and can cause back pain.

When your spine is bent forward unnormally in the waist area, it is called lordosis, commonly known as the Swayback. An abnormal curve in the thoracic region is called kyphosis or humpback. If your spine is curved from side to side, it will be called scoliosis.

Spine
The column consists of 33 bones; But only 24 of them are mobile. This part of the bone is numbered and divided into several regions. From top to bottom of the spine, it has 7 cervix numbered C1-C7, 12 thoracic (middle back) numbered T1-Q12, 5 lumbar (lower back) of the L1-L5, 5 sacred (Base) of the spine)) and 4 tail bones (base of the spine). The sacred vertebrae and coccygeal are fused and cannot be moved.

Intervertebral disks
You have 23 intervertebral disks; Between each vertebra, except L5-S1. These discs act as pillows or pillows for the spine. The disc itself consists of a strong outer layer called a fibre ring and a soft gel center called the nucleus pulposus. As we age, these discs begin to dry out because they lose the ability to absorb water and can become fragile and flattened, which makes them less likely to absorb shock or strength in the spine. This decrease in fluid is also one of the reasons why it’s smaller and smaller as you grow older.

Joints in terms of
Your spine’s articular side allows you to move while bringing together your spine. They are located at the back of the spine; You have two at the top and two at the bottom. The top is connected to the upper vertebrae, while the lower ones are connected to the lower vertebrae.

Ligaments
The ligament is used to unite the vertebrae, stabilize the spine and protect the intervertebral discs.

Muscles
The back muscles are used to stabilize the spine; There are two main groups, Extensers and flexors. The extendings allow us to rise and lift objects and cling to the back of your spine. The flexibility allows us to flex and lean forward. These muscles are located on the front of our body and include the abdominal muscles.

Spinal cord
The spinal cord is on your spinal canal and is about 18 inches in length. The spinal cord is used to send information to the body and the brain and any resulting damage can lead to loss of sensation or motor skills under injury.

Spinal nerves are used to send information to the body and control sensations and movements. There are 31 pairs of nerves in the spine, 8 in the cervix, 12 in the chest, 5 in the lumbar, 5 in the sacrum, and 1 in the Coccygeus. Each of these nerve pairs is responsible for certain areas of the body.
