Hip bone, also known as hip bone, is located on both sides of abdomen. It is an irregular big bone that expands irregularly from the center to the top and bottom.

Generally, the position of the belt is the position of the hip bone, which connects the spine above and the thigh below.

In some vertebrates (including pre-adolescent humans), it consists of three parts: ilium, ischium and pubis.

Extended data

Limb bones include upper limb bones and lower limb bones, which are composed of limb bones connected with trunk and free limb bones. The number and arrangement of upper and lower limb bones are basically the same, characterized by light and flexible upper limb bones and thick and firm lower limb bones, which play a role in supporting and moving the body and are closely related to human upright walking.

The upper limb bone consists of clavicle, scapula, humerus, radius, ulna and hand bone. The joints formed by upper limb bones include shoulder joint, elbow joint and hand joint. These joints make people more dexterous at work.

The lower limb bone consists of hip bone, femur, tibia, fibula, patella and foot bone. Hip bone is connected with sacrum and coccyx in trunk bone to form a ring called pelvis, which is a bone component between trunk bone and limb bone, and has the functions of transmitting weight, supporting and protecting internal organs.

Since puberty, there have been obvious gender differences in pelvis, such as the wide and short pelvis of women and the narrow and wide pelvis of men. The characteristics of female pelvis are mainly related to pregnancy and delivery function.
