Pubis — the structure and function of a woman”s pubic bone
The pubic bone, also known as the pubic bone, is located in front of the pelvic girdle. The bones behind the back and the sciatic nerve bone form the cup-shaped shape of the pelvic girdle. The two halves of the pubic bone are connected at the center by cartilage called the pubis.

The large bones at the back of the pelvic girdle are raised. These bones are located almost directly above the femur and are often noticeable in women and people with little body fat. The pubic bones are not visible from the outside of the body and connect the anterior half of the pelvic girdle.
Anatomy
The pubic bone is located at the front of the body, just below the abdomen. This area provides structure and protection to the human genitourinary organs, including the bladder, uterus, ovaries, prostate and testicles. The largest part of the pubic bone is called the pubic tubercle, which is located at the highest point of the pubic bone. The back of the pubic bone is connected to the ilium, one of the bones in the back of the pelvic girdle. The area of connection between the ischium and pubis is limited by a fixation hole and a fixation groove. On this dorsal surface is the pubic tubercle with the pubic bone and ligaments. The pubic area where the pubic tubercle originates from the ilium is called the superior pubic tubercle. Between the superior pubic ramus and the top of the pubis is the pectineal line, which is another area into which muscles and ligaments insert for stabilization. Directly opposite the superior pubic ramus is the inferior pubic ramus, which leads to the external body of the pubis.
The pubic bone then bends and turns into central cartilage. This arched area of bone is called the pubic arch, which is also connected to the pubic symphysis, where the two ends of the pubic bone are located.
Anatomical options
One of the most important anatomical variations of the pubic bone is the difference in pelvic size. This means that the angle of the pubic bone and the distance between the hip points may be different. These include the angle of the pubic arch, the length of the pubic symphysis, and the radius of the socket into which the femur is inserted. Changes in the pubic symphysis with respect to its ability to degrade are also observed. The human pelvis can be divided into types according to the shape of the entrance.
- Gynecoid. Normal female pelvis. Most suitable for childbirth, as it has a round hole.
- Android. Male pelvis. The entrance shape is triangular.
- Anthropoid. The hole has an oval shape, elongated along a vertical line.
- Platypeloid. Oval entrance shape located along a horizontal line.
It should be noted that android, human and plastic types of pelvic opening are signs of cesarean section.
Function
The main function of the pubic bone is to protect the intestines, bladder and internal genital organs. The pubic bone also connects to the femur, providing support next to the body and allowing the legs to move further down. The pubic bone connects to the back bones of the pelvic girdle, holding them in place and allowing a circular structure to connect the upper half of the body to the lower half.

The pubic bone also has several skeletal landmarks that connect and support muscles, cartilage, ligaments, and tendons. Each of these structures provides connection to the joints, bones, and structures of the body. The symphysis pubis has little motor function because it stabilizes the pelvic girdle. The cartilaginous pubic symphysis has little movement in its loose connection with the two reproductions of the pubic bone. However, the main task of this cartilage is also stabilization. All organs of the pelvic girdle have complex innervation. This means that there are several major nerves running through the pelvic girdle and its structures.
What is a pelvis?
“The pelvis refers to the lower abdomen in both men and women,” says Guillory, a professor of gynecology in the US. An important function of the pelvic region is to protect organs used for digestion and reproduction, which are vital, she says. “Another important role is hip support.”
The pelvic bones form a bowl
The human pelvis is formed by three fused bones.
- Ilium. The largest bone that widens upward.
- Ischium. Located at the bottom, it has the shape of an arc. The ischial tuberosities are located on it, which take on the weight of the body when a person sits.
- Pubic bone. It is formed by the pubic bones and is located in the front of the pelvis.

The pelvic floor is a trampoline
At the bottom of the pelvis is the pelvic floor. To maintain strength, it can be strengthened with Kegel exercises. The pelvic floor looks like a mini yam made up of hard muscle. Like a trampoline, the pelvic floor is flexible and can move up and down. It is also the surface of the pelvic organs: the bladder, uterus and intestines. It contains the vagina, urethra and anal cavity.
The pelvis plays a key role when walking
Anyone who has had a pelvic bone fracture or pelvic muscle strain knows how important the pelvic bones are for functions such as walking and standing. The pelvis also serves as a strong base for the attachment of the spine and legs,” says Ghiori. “The structural features of the pelvis were transferred to the immediate person. It provides balance and distributes the load. Smooth movement is ensured by a number of ligaments, especially those involving the ilium.
The female pelvis can change size
Gillogly states that. “To accommodate the baby during pregnancy and allow for a natural birth, the female pelvis is typically larger and wider than the male.” However, the female pelvis narrows with age without the need for support. Changes in the shape of the pelvis are considered an important part of our evolutionary history because they changed when we began to walk upright.
Pregnancy permanently changes the pelvis
During pregnancy, the body releases a hormone known as relaxin, which helps the body adapt to the growing baby and softens the cervix. However, the following happens. During pregnancy and childbirth, the joints between the pelvic bones weaken and move slightly apart,” says Ghiori. However, lilac can weaken the joints and cause a pain syndrome known as symphysis-pubic dysfunction (SPD), even in the upper thighs during walking and other activities. Many women with this condition are forced to wear a pelvic girdle. It usually goes away after pregnancy ends. In such situations, physical therapy is required.
The pelvis is prone to accidents
According to the American College of Surgeons, approximately 8-9% of cerebrovascular accidents occur in the pelvis. “These accidents include falls, being hit by a car, or being hit by a bicycle or moving vehicle. These serious injuries result in pelvic fractures or dislocations, and sometimes even injury to the internal organs protected by the pelvis,” says Guillory. So, be careful with your pelvis. In severe cases, pelvic fractures may require pins, rods, surgery, or immobilization.
