The pelvis includes a belt of the lower extremities framed by hip joints. This part of the skeleton to some extent continues the spinal column and performs many functions in the human body. The pelvis serves as a junction of the lower extremities and the trunk of people. It is divided into large and small.
Pelvic structure
You can highlight certain components in the named part of the skeleton: the sacrum, tailbone and two pelvic bones. The latter are among the largest in the body. They are endowed with an atypical structure and are primarily responsible for the support function of the skeleton. The pelvic bones are held together by joints in the ring and form the cavity of the same name.
The pelvis of children and adolescents under the age of sixteen is formed by three separate bones, over time they grow together and begin to function as a single bone.
Differences in the structure of the pelvis change throughout a person’s life. This factor can be influenced by biological processes occurring in the body, professional causes and unexpected twists of fate, which include injuries or the occurrence of pathological processes in the pelvic bones or spine.
From the pelvic bones of the skeleton, you can easily find out what gender people belong to. This fact is taken into account during archaeological excavations or during medical examinations.
The difference between the male pelvis and the female
The pelvis of a woman has pronounced distinctive features. He performs an important function - takes part in childbirth. This part of the skeleton is the channel through which the baby moves, seeking to leave the womb of the mother. The dimensions of the female pelvis are wider and shorter than those of the male. The joints are located at a greater distance, the bones are thinner than in men. The structure of the female pelvis is also distinguished by the shape of the sacrum; it is wider and less prominent in women than in men.
The shape of the angle of the pubis of the weaker sex is straighter than that of men, the wings of the pelvis are deployed, the protrusions of the ischial bones are located at a distance. In front and on the sides of the pelvis are nameless bones, and behind the tailbone, continuing the spinal column. The hole of the woman is similar to the transverse oval, and the man to the longitudinal.
Sizes of the female pelvis
To make a forecast of the birth process and prevent complications, much attention is paid to size. But to measure the large pelvis is as accurate as possible, but calculating the size of the small is not possible, so they stem from the size of the large. It is necessary to have information about them in order to determine whether they correspond to the circumference of the head of the fetus being born.
The female pelvis is endowed with an entrance, cavity and exit. There are direct, transverse, oblique right and left pelvic sections.
The exit from it is covered in women by the bottom, consisting of three layers of muscle tissue, covered with a connective tissue membrane. The pelvic floor performs many necessary functions.
The pelvic floor serves as a support for the genitals located inside, and favors their correct placement. It also holds other internal organs. During the course of labor, the muscle layers of the pelvic floor of a woman undergo stretching and form a tube that continues the bone channel.
The female pelvis is measured with an instrument called a tazometer.
Pelvic organs
The organs of the human body have their own special structure and location. It is necessary to have an idea of where the main organs are located in order to be able to determine which one delivers pain before visiting a specialist. The pelvis is the location of a large number of vital organs of the human body.
The organs of the female pelvis, as well as the male, are concentrated in the plane formed by its bones. In medicine, they are divided into general, which include the bladder and rectum, as well as purely female and male.
The bladder, similar in shape to a turnip, is located behind the junction of the pubic bones, separating from them with fiber. When this organ is filled, it comes in contact with the abdominal wall. The size of the bubble can vary depending on the measure of its fullness.
The main task of the rectum is the accumulation and elimination of digestive waste from the human body.
Genital anatomy
The genitals of the female pelvis carry out the processes of fertilization and the birth of a new life, thanks to them, the development of sex hormones in the fair sex occurs. These organs are located outside and inside the pelvis.
The genitals located outside include the pubis, covered with a layer of fat and hair, the labia minora and labia minora, the clitoris:
- The clitoris refers to small, but with special sensitivity and importance of the organs.
- Small lips are folds located between the large lips and the entrance to the vagina, they can be seen outside the large lips and be more saturated in color. They are able to become larger at the time of sexual desire.
- Large labia are located on the sides of the genital fissure. Their skin is covered with hair from the outside, sweat and sebaceous glands are present on it. Inside they are covered with the finest pinkish skin.
- Under the large and small lips is a hole designed to remove urine from the body. Under it there is a hole in the entrance to the vagina, which closes the hymen in innocent girls.
Internal organs
These genitals are located inside the female pelvis, therefore they are called internal:
- Vagina. It is a muscle elastic tube of a certain length.
- The uterus, which is a muscular organ and includes the body and neck. Her body is in the very center of a woman's pelvis. The estuaries located in the upper corners are the points of attachment of the uterus to the tubes.
The walls of the uterus are covered by the endometrium. Under the influence of sex hormones, he is waiting for an egg, which has been fertilized, and if it does not appear, leaves the uterus, causing menstrual bleeding.
The purpose of the uterus of a woman is to be a receptacle for the fetus, it develops in it.
The female pelvis is the location of the ovaries, which are located on the sides of the uterus. They produce and contain many eggs that mature here. Ripen eggs are sent to the fallopian tube, where they can expect sperm. If fertilization has occurred, then the egg passes through the tube into the body of the uterus.
MRI of the pelvic organs in women
Recently, magnetic resonance imaging has become one of the most popular diagnostic methods. With its help, it is possible to really study the female pelvis and get comprehensive information about the state of all organs of the human body. MRI can not have a harmful effect on the body, although it has certain limitations.
Carrying out MRI of the pelvic organs in women makes it possible to study in detail the condition of the internal organs, to identify the presence of pathological processes in them in the early stages of development. It is able to greatly facilitate the diagnosis of diseases, to assist in the selection of the right course of treatment.
When conducting an MRI, a person who has taken a horizontal position is placed in the camera of a special tomograph. In it, a certain part of the body is scanned.
In the field of gynecology, safety plays a special role, since health problems can have a harmful effect on the development of the baby, even if a woman does not expect a baby during the diagnosis.
Key Indications for Using MRI
MRI, as a rule, is prescribed for patients with certain symptoms:
- the presence of neoplasms;
- pain in the pelvic area;
- the presence of stones or sand in the bladder;
- problems in the development of the genitourinary system;
- injuries in the pelvic area.
The female pelvis needs careful attention and timely research.
