4. My sister is fourteen years old and is in the second grade of junior high school. She is tall, 1.74 meters, just like walking on stilts. She is thin and looks like a bamboo pole.

She is a cheerful and generous girl. Tall, long hair, a pair of small eyes with single eyelids, plus a glib mouth.

At first glance, she is quite tall, in good shape, neither fat nor thin, and she is a piece of dancing material. Look carefully, she has ear-length short hair, and always wears two hair clips on her head, one on the left and the other on the right. Her hair is tightly tied behind her ears, revealing a smooth and fair face.

Height refers to the vertical distance from the vertex (V) to the ground. Generally, the unit is "centimeter", and "meter" is commonly used. Height is the length of the longitudinal part of the human body, which originates from the longitudinal growth of the human body and is greatly influenced by genetic factors. The height development of girls is earlier than that of boys, and the rapid growth period is from 12 to 13 years old.

19-23 years old stops growing, while the height of boys develops late. 15- 16 years old is a rapid growth period, and stops growing at 20-25 years old. The long bones and vertebrae of the limbs have ossified and their height has stopped growing.

There are many factors that affect height, such as heredity, nutrition, exercise, environment, living habits, race, endocrine, sexual maturity (menarche age 18 ratio1height 5 cm), distant marriage, medical progress and so on.

Basic knowledge:

Experts remind that human physical development is a very complicated process, from top to bottom, from near to far. The head develops the earliest. At birth, the head length of the newborn is adult 1/2.

The length of the newborn's head is 65438+ 0/4 of its own length. In contrast, the development of lower limbs is late, and the newborn is only 1/4 of that of adults at birth. Therefore, the development of long bones of lower limbs after birth has the greatest influence on height.
