Where the buttocks refer, I don t know

The middle part above the buttocks is the lumbar vertebrae, and the junction with the buttocks is the fifth lumbar vertebra, flanked by the muscles and fascia of the lumbar region.

If the user has pain on both sides of the buttocks, it is more common in lumbar muscle strain or lumbar myofasciitis, which is related to strain, injury, and cold, resulting in obvious soreness and pain on both sides of the buttocks.

If there is pain in the middle of the buttocks, it is more common in the lumbar spine degeneration, bone hyperplasia, lumbar disc herniation, lumbar spinal stenosis or lumbar five vertebral body slippage, causing obvious pain and tenderness in the middle of the buttocks, and the pain will be significantly aggravated when bending over and moving, sometimes accompanied by radiating pain in the buttocks and legs.

The buttocks are the junction of the waist and the legs, and the skeleton is the pelvis composed of two hip bones and sacrum, and the hypertrophic and wide gluteus maximus, gluteus medius, and gluteus minimus are attached to the outside, as well as the relatively small piriformis muscle. The shape of the buttocks is backward, its upper edge is the iliac crest, and the lower border is the gluteal cleft. When the human body is upright, the entire buttocks are square, and the hip sockets on both sides are prominent.

There is a difference between the shape of the buttocks of men and women. The female buttocks are plump and fatty, and the angle of the posterior superior iliac crest is 90°; Males have smaller, square-shaped, angular protrusions, more pronounced gluteal fossa, and the posterior superior iliac crest is 60°.

Hip circumference: The horizontal girth of the hips at the most prominent part of the hips, measured using a soft ruler.

Hip width: The distance between the most prominent parts of the buttocks outward.

Hip thickness: The horizontal straight line distance between the most prominent parts of the hips in front and back of the hips parallel to the sagittal plane at the height of the most prominent part of the hip backwards.

Suprafemoral length: The distance from the waist line (WL) to the perineal point (CR).

The meaning of the rump: the upper end of the hind limbs of a quadruped body where the waist is connected. The part of the back of the body of various animals that has no obvious signs or boundaries.

The buttocks are the junction of the waist and the legs, and the skeleton is the pelvis composed of two hip bones and sacrum, which are attached to the gluteus maximus, gluteus medius, gluteus minimus, and piriformis muscles. The hip shape is backward, with the iliac crest on the upper edge and the gluteal cleft on the lower border. When standing upright, the buttocks are square, and the buttocks on both sides are prominent.

In females, the buttocks are plump and fatty, and the angle of intersection of the posterior superior iliac crest is 90°; Males have small, square hips, prominent edges and corners, prominent gluteal fossa, and an angle of 60° to the posterior superior iliac crest.

The tightness of the hip muscles affects the perception of the height of the breech position, but does not change the height of the hip line. The height hip circumference index is greater for women than for men, because the hip width is not hip curl. Women of the same height have wider hips.

"Female pelvic width" refers to the height of the pelvic width index, shoulder width and pelvic width index, which is greater for women than for men, and the average pelvic width for men is slightly larger than that for women.

Hips

Hip circumference: Asian male average, Asian female average; The average for European and American men is for European and American women. Height hip circumference index = (hip circumference height) 100: Asian male average, Asian female average; The average for men in Europe and the United States, and the average for women in the United States.

It can be seen that the average hip circumference is about the same for both sexes, and the average (hip circumference and height) of 100 is significantly greater for women than for men. That is, women have comparatively larger buttocks.
