Female pelvis: anatomy, structure. MRI of pelvic organs in women

The pelvis includes the lower extremity belt, framed by the hip joints. This part of the skeleton extends the vertebral column to some extent 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.

Structure of the pelvis

It is possible to distinguish certain components in the named part of the skeleton: the sacrum, the coccyx and the two pelvic bones. The latter are among the largest in the body. They are endowed with an atypical structure and are responsible, first of all, for the supporting function of the skeleton. The pelvic bones are fastened together by the joints in the ring and form the same cavity.

The pelvis of children and adolescents until the age of sixteen forms three separate bones, with the passage of time they coalesce and begin to function as a single bone.

Differences in the structure of the pelvis vary throughout the life of a person. This factor can affect the biological processes that occur in the body, professional causes and unexpected twists of fate, which include trauma or the course of pathological processes in the pelvic bones or spine.

On the pelvic bones of the skeleton you can easily find out to what gender the people belong. This fact is taken into account during archaeological excavations or during medical examinations.

Difference of the male pelvis from the female

The woman's pelvis 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, striving to leave the mother's womb. The size of the female pelvis is broader and shorter than that of the male. Joints are located at a greater distance, the bone is thinner than in men. The structure of the female pelvis is also distinguished by the shape of the sacrum, it is wider in the representatives of the fair sex and is less forward than in men.

The shape of the angle of the pubic floor of the weaker sex is more direct than that of men, the pelvic wings are unfolded, the protuberances of the ischium bones are located at a distance. Anterior and lateral sides of the pelvis are bounded by anonymous bones, and behind the coccyx, which extends the vertebral column. A woman's hole looks like a transverse oval, and a man has a longitudinal oval.

Female Pelvis Sizes

To make a prognosis of the process of childbirth and prevent complications, much attention is paid to the size. But the big pelvis is measured as accurately as possible, but it is impossible to calculate the small size, so they follow from the size of the large one. You need to have information about them to determine if they match the circumference of the head of the fetus.

A female small pelvis is endowed with an entrance, a cavity and an exit. There are direct, transverse, oblique right and left sections of the pelvis.

The exit from it is covered at women by the bottom, developing from three layers of the muscular fabric covered with a connective tissue cover. The pelvic floor performs many necessary functions.

The pelvic floor serves as a support for the genital organs located inside, and favors their correct placement. It also keeps other internal organs. During the course of labor, the muscular layers of the pelvic floor of the woman are stretched and form a tube that continues the bone channel.

The female pelvis is measured with a tool called the tasometer.

Organs of the pelvis

The organs of the human body have their own particular 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 gives painful sensations 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 one, 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 the purely feminine and masculine.

The bladder, similar to the form on the turnip, is behind the connection of the bones of the pubis, separating from them with fiber. When this organ is filled, it comes into contact with the abdominal wall. Dimensions of the bladder can vary depending on the measure of its fullness.

The main task of the rectum is the accumulation and excretion of digestive waste from the human body.

Anatomy of the genitals

The sexual organs 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 occurs in the beautiful sex. These organs are located outside and inside the pelvis.

The genitals located on the outside include a pubis covered with a layer of fat and hair, large and small labia, a clitoris:

1. Clitoris refers to small, but very sensitive and important organs.
2. 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 color. They are able to become more at the moment of sexual attraction.
3. Large labia lips are located on the sides of the genital slit. Their skin on the outside is covered with hair, it contains sweat and sebaceous glands. Inside they are covered with the finest skin of a pinkish color.
4. Under the large and small lips is a hole, designed to remove urine from the body. Under it there is an opening of the entrance to the vagina, which closes the innocent girls with a hymen.

Internal organs

These genitals are located inside the female pelvis, therefore they are called internal:

1. Vagina. It is a muscular elastic tube of a certain length.
2. Uterus, which is a muscular organ and includes the body and neck. Her body is in the very center of the woman's pelvis. The mouths, located in the upper corners, are the points of connection of the uterus to the tubes.

The walls of the uterus cover the endometrium. Under the influence of sex hormones, he is in anticipation of an ovum that has undergone fertilization, and if it does not appear, leaves the uterus, causing menstrual bleeding.

The purpose of the woman's uterus is to be a receptacle for the fetus, in which it develops.

The female pelvis is the location of the ovaries that are located on the sides of the uterus. They produce and contain many eggs that mature here. Ripe eggs are sent to the fallopian tube, where they can expect sperm. If fertilization has occurred, then the egg through the tube gets into the body of the uterus.

MRI of pelvic organs in women

Recently, magnetic resonance imaging has become one of the most popular methods of diagnosis. With her help to really study the female pelvis and get exhaustive information about the state of all organs of the human body. MRI can not have harmful effects on the body, although it has certain limitations.

Conducting MRI of pelvic organs in women makes it possible in detail to study the condition of internal organs, to reveal the presence of pathological processes in them at early stages of development. It is able to greatly facilitate the diagnosis of diseases, to help in selecting the right course of treatment.

When an MRI is performed, the person taking the horizontal position is placed in the chamber of a special tomograph. In it, a certain part of the body is scanned.

In the field of gynecology, a special role belongs to safety, since health problems can have a harmful effect on the development of the baby, even if the woman does not wait for the child during the diagnosis.

The main indications for the use of MRI

MRI, as a rule, is prescribed to patients with a certain symptomatology:

• The presence of neoplasms;
• Pain in the pelvis;
• Presence of stones or sand in the bladder;
• A malfunction in the development of the genitourinary system;
• Trauma in the pelvic area.

The female pelvis needs careful attention and timely research.
