The Anatomy of a Woman’s Butt Basics

The ‘Bum’ also known as ‘Buttocks’ refers to the fleshy parts of the human body located on the posterior or the back side. They comprise the pelvis (bones), butt muscles, fatty deposits laid over the buttock muscles and the skin that is holding everything in place.  It is important to understand the anatomy of a woman’s butt especially if you are considering changing the physical shape through exercise or other ways.  Knowing which areas to target and working out the muscles can improve the appearance of the butt naturally. However, some of these parts cannot be changed for example the bone structure.

Now let’s take a look at each of these components:

1) The Pelvis

This is the region between the upper body (trunk) and the legs. It is made up of three types of bones: hip bones; sacrum and coccyx. The female pelvis is structurally different from the male pelvis in that, it is larger and broader primarily to create space during child birth. The male pelvis is taller, narrower and more compact. This difference becomes very apparent during puberty and is responsible for the physical appearance of a wider butt in ladies. The posterior side of the pelvic region holds the butt muscles. You will also find digestive organs as well as reproductive organs in the pelvis region.

2) The Butt Muscles 

The muscles that shape the female butt are collectively referred to as the gluteal muscles  or “glutes”. Three glute muscles make up the butt as follows:

  1. Gluteus Maximus
  2. Gluteus Minimus
  3. Gluteus Medius

i) Gluteus Maximus

This is the largest of the three gluteal muscles and it is responsible for the shape and appearance of the butt. The larger the gluteus maximus muscles, the more shapely, stronger and rounder the butt will be. In addition, the large size of the muscle makes it responsible for anchoring the human body in an upright position unlike in other primates.

ii) Gluteus Medius

This is the second largest gluteal muscle and it works together with the gluteus minimus to support the body during movement.

iii) Gluteus Minimus

This is the smallest of the three gluteal muscles and it is located directly beneath the gluteus medius muscles. It works together with the gluteus medius to support the body during movement.

3) Fatty Deposits

Fat deposits form a major component of the female butt and their purpose is to cover up the gluteal muscles. This gives the butt a soft squishy feeling in your hands when you touch them. Buttocks need to have a good amount of fat around them in order to make sitting comfortable. Generally females have higher fat deposits in their bodies compared to males. The fatty deposits are responsible for the appearance of the butts. The accumulation of fat in women is mostly around the pelvic, buttocks and thighs area while in the men, it is in the belly area.

Some women tend to accumulate a lot of fat around the butt area while some don’t. This is attributed to their genetic make up and their hormone levels. Estrogen is the hormone responsible for fat storage around the buttocks area. Higher levels of estrogen promote the storage of fat in the booty region. This means that in order to increase the booty size, one can partake in exercises to build gluteal muscles and / or increase the estrogen levels in the body through taking butt-enhancing supplement pills like gluteboost. Macaroot, a Peruvian root has also been known to increase the levels of estrogen in the body and therefore would be a good natural butt builder.

4) The Skin

The skin is the outer protective layer around the buttocks that protects the inner organs against harm as well as sense pain, temperature and generally whatever is around the area.  The outermost layer called the epidermis is the one that is visible, and constantly shedding dead skin. Beneath it is the dermis which contains nerve endings, and capillaries for blood flow. An even deeper layer is the hypodermis which has fatty deposits that serve as a cushion to protect the muscles and bones from bumps and falls. The skin around the buttocks can be smooth giving the area a very beautiful appearance or it could suffer from various conditions like acne, black spots, itchiness, stretch marks, cellulite and rashes. Most people are born with a smooth skin around the buttocks area but as they age, there is no guarantee that the skin will stay the same.
