head shape features


The shape of the skull determines the shape of the head. It not only shows differences in gender and age, but also includes various personality differences.


1. The appearance characteristics of male and female heads


(1) The male head is larger and tends to be square, the forehead is backward, the eyebrow arch and nasal bone are more prominent, the mandible and forehead are square, and the occiput is prominent. In appearance, the male head line tends to be straight, and the body undulates greatly.


(2) The head volume of females is smaller, and the bulge and nodules of the face are not as significant as those of males, but the frontal and parietal colliculus are more prominent. The forehead is straight, the mandible is pointed, and the face tends to be rounded. In appearance, the lines of women's heads tend to be softer, and the body undulations are less.


2. Head shape features of old and young


(1) The apical mound of the head of the elderly is very prominent due to sparse hair, and the teeth are lost, so the gums are sunken. The face is shortened, the facial features are concentrated, the mouth is retracted, and the lower beard is prominent and the front is raised, which are the distinctive features of the elderly head.


(2) The volume of the brain and skull in the head of a child accounts for 5/6 of the head, and the facial skull only accounts for 1/6 of the head. The parietal bone is raised, the frontal mound is high and prominent, and the mandible is small and round. The large skull, the adducted forehead, and the shortened distance from the root of the nose to the lips are the most striking features of the infant's head.


3. Different types of head features


Human head muscles are relatively shallow, and the basic shape of the head is determined by the shape of the skull. The traditional Chinese concept of "eight-shaped" of human appearance is an excellent summary of the shape and characteristics of the head.


Analyzing the different characteristics of the "eight grids", it can be found that the three head shapes of "Jia", "You" and "Shen" are determined by the pointed or square shape of the parietal bone and mandible; The three head shapes of "Guo" are determined by the ratio of the width of the cheekbones to the length of the head; the two head shapes of "Yong" and "Wind" are determined by the width, opening and closing of the mandible.
