The epiphysis exists near the ends of the human skeletal joints, and a linear cartilage tissue can be seen near the ends of the bone joints in general hospitals through X-rays. During the period of growth and development, the cartilage tissue of the bone constantly has deposits of calcium, phosphorus and other minerals, and the cartilage component of the epiphysis becomes a real bone structure, which is the process of human growth. It is mainly the growth of the ends of the bony joints of the long bones that makes the human body grow taller. Most of the bones in the human body have epiphyses at both ends, and during puberty, stimulated by hormones and growth hormone, the peak of human body growth comes and the growth rate is faster. After the puberty period, the epiphysis is not very obvious, which is the folk saying that the epiphysis closes, gradually slowing down the growth and growth rate, until the growth and development stops, the epiphysis will also disappear.
