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.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
