How many lumbar vertebrae are there

In fact, our lumbar vertebrae are very similar to our spine. We can see on X-rays that our spine is connected one by one. In fact, our lumbar vertebrae are also structured like this. Many people count their vertebrae when they are bored. Although the lumbar vertebrae are not as obvious as the spine, they are also connected one by one. So how many lumbar vertebrae are there?

There are five lumbar vertebrae, which are characterized by thick vertebral bodies, kidney-shaped cross-sections, and oval or triangular vertebral foramina. The upper and lower articular processes are thick, and the articular surface is almost sagittal. The oval protrusion on the posterior edge of the superior articular process is called the mastoid process. The spinous process is broad, short, plate-like, and extends horizontally toward the back. The spaces between the spinous processes are relatively wide, and lumbar puncture, also known as lumbar puncture, can be performed clinically here.

The human body has 7 cervical vertebrae; 12 thoracic vertebrae; 5 lumbar vertebrae; 9 sacrum and coccyx. A total of 24 vertebrae, 5 sacrums, and 4 coccyxes make up our normal spine.

The spine has the functions of supporting the trunk, protecting the internal organs, protecting the spinal cord and performing movements. The upper end of the spine supports the skull, the lower end is connected to the hip bone, the middle is attached to the ribs, and serves as the posterior wall of the thorax, abdominal cavity and pelvic cavity.

There is a trick that can easily remember the number of cervical vertebrae, thoracic vertebrae, lumbar vertebrae, sacrum and coccyx, "eat breakfast at 7 am, lunch at 12 noon, dinner at 5 pm, and supper at 9 pm". Morning, noon, afternoon and evening correspond to the cervical vertebrae, thoracic vertebrae, lumbar vertebrae, sacrum and coccyx respectively. The time corresponds to the corresponding number of blocks.
