The cartilage between the epiphysis and the epiphysis is shown as a wider translucent band on x-rays of young children, it gradually becomes shorter with age, and when the cartilage between the epiphysis and the epiphysis is completely ossified, it forms a tight seam called the epiphyseal line. The epiphyseal plate itself is a layer of cartilage. It is a type of cartilage, different from the usual cartilage that does not ossify for life (such as the cartilage in the ears and nose), but the cartilage that gradually ossifies as it grows. When we grow taller, the epiphyseal plate is gradually ossifying, but itself does not change less (thin), thus ensuring the growth of our long bones. When puberty begins to develop for a period of time, with the secretion of sex hormones, it can be understood that the epiphysis gradually ossifies again after there is no ability to continue to grow, all the ossification is finished, and there is no more space and raw materials for growth. The blurring of the epiphysis means that the epiphysis is going to close, but the closure of the lower limbs will be later than that of the upper limbs. Generally speaking, the epiphysis of women closes earlier than that of men, usually around the age of 18. Once the epiphysis is closed, the possibility of growing taller is very small. Generally speaking, the growth of height slows down after the first menstruation in women, and the epiphysis closes around the age of 16 to 18, while in men it closes around the age of 18 to 20. Before the epiphysis is completely closed, adolescents should pay attention to maintain a good sleep, participate in more sports, timely supplementation of calcium, balanced nutritional structure, and use scientific methods to promote the body to grow taller.
