The cervical vertebrae, thoracic vertebrae and lumbar vertebrae are three important parts of the body. These parts are prone to bone sprains, which is called cervical spondylosis and thoracic and lumbar pain. These symptoms are relatively common in normal times. The causes of these diseases are closely related to our lives. If we want to prevent the disease, it is best to exercise more, not maintain one movement for a long time, and adjust our bad living habits. 1. From the size of the vertebral body. For the same person, the cervical vertebrae are smaller. The thoracic vertebrae are second, and the lumbar vertebrae are the largest; 2. From the form. (1) The cross section of the cervical spine is oval, the cross section of the thoracic spine is heart-shaped, and the cross section of the lumbar spine is kidney-shaped; (2) The articular surfaces of the upper and lower articular processes of the cervical vertebrae are almost horizontal, the articular surfaces of the articular processes of the thoracic vertebrae are almost coronal, and the articular processes of the lumbar vertebrae are thick and the articular surfaces are sagittal; (3) The spinous processes of the 2nd to 6th cervical vertebrae are short and bifurcated at the ends, and the spinous process of the 7th cervical vertebra is The spinous processes of the thoracic vertebrae are relatively long and do not bifurcate at the ends. The spinous processes of the thoracic vertebrae are relatively long, tilted backward and downward, and are shingled. The spinous processes of the lumbar vertebrae are relatively wide and short, and are horizontally plate-shaped and face backward. The interspinous process spaces are relatively wide. (4) There are holes on the transverse processes of the cervical vertebrae - the transverse process foramina. There are upper and lower costal grooves on the upper and lower edges of the junction of the vertebral body and the pedicle of the thoracic vertebrae, and there is a transverse costal groove in front of the end of the transverse process. The relationship between cervical vertebrae, thoracic vertebrae and lumbar vertebrae The human spine is composed of 32 vertebrae, and the ability of a person to stand up is mainly due to the function of the spine. The spine consists of 7 cervical vertebrae, 12 thoracic vertebrae, 5 lumbar vertebrae, 1 sacrum and 1 coccyx. Let’s look at the relationship between the cervical, thoracic and lumbar vertebrae. The human spine consists of 7 cervical vertebrae, 12 thoracic vertebrae, 5 lumbar vertebrae, 1 sacrum (formed by the fusion of 5 sacral vertebrae and 1 coccyx formed by the fusion of 4 coccygeal vertebrae). The spine is surrounded by strong ligaments and can maintain a high degree of stability. The vertebrae are also connected by intervertebral joints and have a considerable range of motion. The motor function of each part of the spine is different. The cervical and lumbar vertebrae have the greatest mobility, the thoracic vertebrae have less mobility, and the sacral vertebrae have almost no mobility. According to the principle of leverage, the vast majority of spinal fractures and dislocations often occur in the junction areas where the range of spinal motion is large or the degree of motion changes, namely the first and second cervical vertebrae, the fifth and sixth cervical vertebrae, the eleventh and twelfth thoracic vertebrae, and the first, second and fourth and fifth lumbar vertebrae. Because the thoracolumbar segment from the eleventh thoracic vertebra to the second lumbar vertebra is the junction of the relatively fixed thoracic vertebrae and the relatively mobile lumbar vertebrae, it is subjected to greater stress and external violence is mostly concentrated here, resulting in more opportunities for injury. Therefore, spinal fractures and dislocations often occur in the thoracolumbar segment. The cervical vertebrae, thoracic vertebrae, and lumbar vertebrae each have their own functions and are connected to each other, and they play an important role in the human body's standing. The vertebrae are also very "united". I hope I can treat my spine well. |
