Human structure: skeleton+muscle (1. 1 cervical vertebra)

Speaking of human bones, I have a lot to say, because I personally prefer to play with sculpture, mostly for the structure of human body and animals, so I still have some research on this aspect. If you don't mind expressing your opinion on one's study, then you can read this article, and maybe we can study the human body together. ?

I will do the above according to some common cognition in art sculpture and medicine.

Human skeleton:?

1, upper body (spine, chest, lumbar spine, arms)?

1. 1, cervical vertebra

1.2, clavicle?

1.3, sternocleidomastoid muscle?

1.4, scapula?

1.5, chest rib?

1.6, lumbar spine?

1.7, humerus?

1.8, ulna, radius?

1.9, metacarpal bone?

I know that there is a saying: "Persuade people to study medicine, thunder every day, and persuade them to learn to pieces", but even many people don't know some common sense. For example, ask a person casually how many bones there are in a person's body. Maybe you don't even know such basic knowledge, and you always feel indifferent because you don't need it. There are too many such people. Anyway, I want to say that this is for life. ?

This is a female skeleton, so men are muscles and women are skeletons. If the skeleton is divided into several parts, which can be regarded as spine, chest, lumbar vertebrae and arms, then the contents of these articles will come out. ?

As can be seen from the above picture, it is ZB(ZBrush's artistic sculpture creation software). There are "seven" cervical vertebrae, and the seventh cervical vertebra is the most prominent. Thin people or ordinary people can touch the bone under the back of the head, which is the seventh cervical vertebra. Generally speaking, with the increase of age, the intervertebral disc becomes thinner, the intervertebral foramen becomes narrower, and the lower end is easy to grow. This is cervical spondylosis. Many people who often work on the computer for a long time, such as me, are prone to cervical spondylosis by staring at the computer all the time. After a long time, the cervical spine is straight and slowly bends, so it is generally recommended to put the screen on your chest or put a book on it when watching the computer, so that the screen is as parallel as possible to the eye line of sight. Moreover, once the bone is swollen and bent, it will compress the spinal cord and make the lower limbs walk unsteadily. If the spur grows on one side of the spine, it can stimulate or compress the vertebral artery, causing dizziness, headache, decreased vision and other symptoms of insufficient blood supply to the brain. ?

Typical cervical vertebrae are: 3, 4, 5, 6, atypical cervical vertebrae are: 1, 2, 7 (unit/joint)?

Typical cervical features:?

The vertebral body is small, with the left-right diameter larger than the front-back diameter, the upper surface protruding (forming a lateral joint) and the lower surface concave;

Vertebral foramen is large and triangular;

Vertebral artery runs in all transverse foramen of cervical vertebra (typical or atypical) (vertebral artery and vein, but no vertebral artery runs in transverse foramen of the seventh cervical vertebra); ?

1, 2, 7 The first vertebra of cervical vertebra has no vertebral body, and it is called atlas. It is connected with the dentate fossa of the second cervical vertebra as a joint point, which can control the amplitude of shaking head and nodding head. Then the seventh cervical vertebra is the most prominent one and can be used as a symbol of cervical vertebra.

As can be clearly seen in the picture below, dentures and linkage joints?

About the nerves and blood vessels connected to the cervical vertebra?

After that, let's talk about the nerves and blood vessels connected to the cervical spine.

Ok, this is the first chapter, cervical vertebrae. Chapter one: Try the water first, and then you continue to follow the new one?
