How many segments are there in the cervical spine, and what is the function?

There are a total of seven cervical vertebrae in normal people, and the seven segments are anatomically distinct, especially the anatomical differences of the first cervical vertebrae, the second and seventh cervical vertebrae. The first cervical vertebra is called the atlas vertebra and has no vertebral body. The second neck is called the pivotal vertebrae, and the vertebral body is a protrusion.

The first cervical vertebra is connected to the second cervical vertebra to form the atlantoaxial joint, which needs the support of the atlantoaxial joint when turning the head from side to side because the atlantoaxial joint itself is mobile. The seventh cervical vertebra is called the large vertebrae, and its anatomical feature is that the spinous process is particularly long, and when people look down, they can feel a distinct bony protrusion on the back of the neck, called the greater vertebral spinous process. There are a total of seven segments in the cervical vertebrae.

There are 7 cervical vertebrae, 5 lumbar vertebrae, and a total of 33 human spines.

The spine is composed of 26 vertebrae, that is, 24 vertebrae (7 cervical vertebrae, 12 thoracic vertebrae, 5 lumbar vertebrae), 1 sacrum, 1 coccyx, since the sacrum system consists of 5 pieces, the coccyx is composed of 4 pieces, and the normal spine can also be composed of 33 pieces.

7 cervical vertebrae. 12 thoracic vertebrae.

5 lumbar vertebrae. The sacrum 1 spine, commonly known as the "backbone bone", is the axial bone of humans and vertebrates, which is composed of several irregularly shaped vertebrae connected by intervertebral discs and ligaments. It has the effect of supporting the trunk and protecting internal organs.

The human spine consists of seven cervical vertebrae, twelve thoracic vertebrae, five lumbar vertebrae, one sacrum (composed of five sacral vertebrae), and one coccyx (composed of four caudal vertebrae). The vertebrae have a spinous process that protrudes dorsally to the dorsal side, which can be felt subcutaneously on the midline of the back, which is one of the important landmarks for meridian point positioning. Inside the spine there is a longitudinal "spinal canal" that houses the spinal cord.

Under normal circumstances, the spine has four curves forward and posterior, of which the neck and waist are lordosis, and the thoracic and sacral parts are kyphosis. The curvature of the spine is not only conducive to an upright posture, but more importantly, it increases the elasticity of the spine, which can cushion the best when walking and jumping, and has protective significance. This curvature is also often caused by long-term malposture or the influence of disease, causing deformity and becoming a hunchback.

Normal 7 segments 1, weight-bearing, support the head, and complete flexion and extension, rotation, and lateral flexion movements.

2. Protect the spinal cord.

3. Protect the blood vessels in the neck, the most important thing is the carotid artery, and maintain the normal blood in the head.

4. Buffering, the most important of which is the cervical intervertebral disc and the surrounding ligament soft tissue.

The cervical vertebrae together form the atlantoaxial joint, which is an important structure for maintaining head rotation, and plays a more significant role in rotation than other vertebral bodies.

32 vertebrae, 7 cervical vertebrae, 12 thoracic vertebrae, 5 lumbar vertebrae, 3 sacral vertebrae. Caudal vertebrae 5 segments. A total of 32 vertebrae.

According to your analysis of the situation, medically the cervical vertebra is 7 segments, and the 8th segment is the first thoracic vertebrae. However, if cervical spondylosis can also affect the changes of the thoracic spine.

The cervical spine is made up of seven cervical vertebrae.

Except for the first cervical vertebra and the second cervical vertebrae, there is an intervertebral disc between the other cervical vertebrae, plus the intervertebral disc between the seventh cervical vertebra and the first thoracic vertebrae, and the cervical vertebra has a total of 6 intervertebral discs.

Each cervical vertebra is made up of two parts: the vertebral body and the vertebral arch. The vertebral body is an oval-shaped columnar body, and the vertebral body is connected to the vertebral arch, which together form the vertebral foramina. All the foramina are connected to form the spinal canal, which houses the spinal cord.

The cervical spine is the smallest segment of the vertebrae in the spine, but it has the greatest flexibility, the highest frequency of activity, and a large weight-bearing segment.

The human cervical vertebrae are seven segments. Adopt it.

The cervical spine has seven vertebral bodies, and the physiological curvature of the cervical spine protrudes forward.

The cervical spine is the most flexible and frequently active vertebral body in the spine, and it is also the part of the spine that is the most worked and affected. The cervical spine is also an important channel for nerves, just like a two-way highway, which is responsible for sending instructions from the brain to all parts of the body, and sending various nerve messages to the brain through the cervical spine.

So we have to take good care of our cervical spine.

Hope it helps.

It's not a few pieces, it's a few sections. There are several vertebrae in the cervical vertebrae, except for the first and second vertebrae, there is a disc between the second and third, the third and fourth, the fourth and fifth, the fifth and the sixth, the sixth and the seventh, the seventh and the thoracic vertebrae, so that there are 6 discs.

But the question is, what is the point of understanding this? If you have a problem with cervical spondylosis, you can take measures directly, you don't need to take anything, whether you shoot or not, how much impact does it have on what way you take it, but in reality, there are always doctors who ask patients to take an X-ray first, as if they can accurately judge after taking this thing, and then tell you to know how to do it**, this is all nonsense, will he study a different set of ** plans for each different patient? His approach is a one-size-fits-all approach.

So what you do now is to find one that suits you among the different **.

Now for cervical spondylosis, lumbar spondylosis, frozen shoulder, lumbar muscle strain, arthritis and other such cumulative chronic muscle inflammation has developed a lot, such as massage massage, acupuncture, cupping, plasters, electrotherapy, injections, medicines, etc., all strange, strange, varied, but these ** have a common fatal flaw, that is, they do not follow a basic ** principle, that is, Lemeikang Chinese medicine ion far infrared pulse penetration ** emphasized, these principles include, 1 correct drug, this is the basis and premise, if the drug is not correct, no matter how many ** are in vain, 2 correct medication methods, this is a guarantee, and these ** can not be done in this regard. 3 insistence, this is the key, many people are always intermittent, fruitless, how can this have the effect. 4 contraindications.

Some people get a little better, and they repeat the previous bad habits and lifestyles, which makes the condition repeat again.

In order to achieve the purpose of the first class, in the first place, the selection of a system like Lemeikang can quickly and efficiently relieve frozen shoulder, cervical spondylosis, lumbar spondylosis, arthritis, rheumatism, lumbar muscle strain and other problems, and play a role in prevention, prevention and prevention. This process is the result of a combination of factors, not only the drug, but also the method of medication, the patient's personal physical fitness, will, will, and cooperation, etc., all affect the final result.
