The waist is an important part of the human body, located between the abdomen and the lower limbs. It is composed of the spine, pelvis and muscles and is an important support part of the body. The anatomy of the lumbar sub is very complex, including the spine, ilium, muscles, ligaments, nerves and blood vessels, and many other parts.

Anatomy of the loin

The anatomy of the loin consists of the following parts:

Spine

The spine is the main component of the loin and consists of 33 vertebrae. Of these, the lumbar spine is the largest vertebrae and the most vulnerable. The main function of the lumbar spine is to support the body weight and protect the spinal cord, as well as to allow bending and rotational movements.

The ilium

The ilium is another component of the lumbar and is located below the lumbar spine. It is one of the largest bones in the body and is connected to the pelvis, acting as a support and protection for internal organs.

Muscles

The muscles of the psoas are mainly composed of the psoas major, psoas quadratus and psoas multifidus. These muscles help keep the spine stable while also allowing for bending and rotational movements.

Ligaments

The ligaments of the psoas are mainly composed of the longitudinal, ligamentum flavum, and ligamentum spinosum. These ligaments help keep the spine stable, while also preventing it from bending or twisting excessively.

Nerves and Blood Vessels

The nerves and blood vessels in the lumbar region mainly consist of the lumbar nerve and the lumbar artery. These nerves and blood vessels provide the lumbar region with adequate blood and oxygen, while also transmitting sensory and motor information.

How to protect the waist

Since the waist is an important part of the human body, we need to take some measures to protect it. Here are some ways to protect the lumbar region:

Correct posture

Correct posture can help us protect the lumbar region. When we sit or stand, we should keep our spine upright and not bend or twist it excessively. In addition, we should try to avoid keeping the same position for a long time, and we can rest and move properly.

Reasonable exercise

Appropriate exercise can help us protect our waist. For example, you can do some low-intensity aerobic exercises, such as walking, swimming and yoga. These exercises can help us strengthen our waist muscles and also improve the flexibility of our body.

Correct posture for lifting weights

Correct posture should be adopted when lifting weights in order to avoid damage to the waist. You should squat your body and use your leg muscles to lift the item while keeping your spine upright.

Correct Sleeping Position

The correct sleeping position can help us protect our waist. You should choose a sleeping position that suits you, such as lying on your side or back, while using a comfortable pillow to support your neck and head.
