: How do you do, Boris! <br><br>: How do you do, Alec! <br><br>: Are you free now? <br><br>: Yes, I am. Let us prepare our Anatomy lesson for tomorrow . <br><br>: Tomorrow we shall have the lesson on the bones. <br><br>: I do not know well the spinal column. <br><br>: I can help you if you like . Can you answer my questions? <br><br>: I am ready. <br><br>: So, at what age does the spine grow most rapidly? <br><br>: In the girls the spine grows most rapidly to the age of 15. In the boys it grows to the age of 19. After the age of 19, the spine grows very slowly. The length of the spinal column is about 40% of the body. <br><br>: That's all right. Now the second question. What do you know about the number of the vertebrae in the spine?<br><br>: The number of the vertebrae may be 32 or 34. Sometimes it may be 37. But I do not know why. Can you tell me? <br><br>: It is because the number of the sacral vertebrae may be five and the number of the vertebrae which compose the coccyx may be from one to five. <br><br>: Thank you. Can you tell me which of the vertebrae have the form different from the others? <br><br>: They are the first and the second cervical vertebrae. The form of these two vertebrae is different because they take part in the flexible connection of the skull and the spine. <br><br>: Thank you. I think tomorrow I shall answer well.
