What is the structure of the vertebra and what role do cartilaginous intervertebral discs play?

Each vertebra consists of a massive part – a body and an arc with several processes. The vertebrae are located one above the other so that their holes coincide, and a vertebral drop forms, in which the spinal cord is located. The spine protects the delicate spinal cord from damage. Between the vertebrae there are intervertebral cartilage discs. Thanks to them, a semi-mobile connection is formed. Cartilaginous tissue is elastic and can stretch and condense. When we sleep, its thickness increases, and when we walk it decreases. As a result, a person is higher in the morning than in the evening.
