The pelvis includes the girdle of the lower extremities, framed by the 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 the junction of the lower extremities and torso of people. It is divided into large and small.
The structure of the pelvis
It is possible to distinguish certain components in the named part of the skeleton: the sacrum, coccyx 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 supporting function of the skeleton. The pelvic bones are held together by the joints into a ring and form the cavity of the same name.
The pelvis of children and adolescents up to sixteen years old form 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 in the body, professional causes and unexpected twists of fate, which include injuries or pathological processes in the pelvic bones or spine.
On the pelvic bonesSkeleton 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 and female pelvis
The pelvis of a woman has distinct distinctive features. It performs an important function - it takes part in childbirth. This part of the skeleton is the channel through which the baby moves, seeking to leave the mother's womb. 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 also differs in the shape of the sacrum, it is wider in the fair sex and less protruding than in men.
The shape of the pubic angle of the weaker sex is straighter than in 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, the pelvis is limited by the innominate bones, and behind the coccyx, which continues the spinal column. The woman's hole looks like a transverse oval, while the man's hole looks like a longitudinal one.
Female pelvic measurements
To predict the birth process and prevent complications, much attention is paid to size. But it is realistic to measure a large pelvis as accurately as possible, but there is no way to calculate the dimensions of a small one, so they follow from the dimensions of a large one. You need to know about them to determine if they correspond to the circumference of the head of the fetus being born.
The female small pelvis is endowed with an entrance, a cavity and an exit. Distinguish between straight, transverse, obliqueright and left section of the pelvis.
The exit from it is covered in women by the bottom, which consists of three layers of muscle tissue covered with a connective tissue sheath. The pelvic floor performs many essential functions.
The pelvic floor serves as a support for the genital organs located inside, and favors their correct placement. It also holds other internal organs. During childbirth, the muscle layers of the pelvic floor of a woman are stretched and form a tube that continues the bone canal.
The female pelvis is measured with an instrument called a pelvis.
Pelvic Organs
The organs of the human body have their own special structure and location. It is necessary to have an idea where the main organs are located in order to be able to determine which one causes 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 ones, 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 bones of the pubis, separated from them by fiber. When this organ is filled, it comes into contact with the abdominal wall. The size of the bubble can change depending on the measure of its fullness.
The main task of the directThe intestine is the accumulation and excretion of digestive waste from the human body.
Genital Anatomy
The genital organs of the female pelvis carry out the processes of fertilization and the birth of a new life, thanks to them the production of sex hormones in the fair sex occurs. These organs are located outside and inside the pelvis.
The external genital organs include the pubis covered with a layer of fat and hair, labia majora and minor, clitoris:
- The clitoris is a small but sensitive and important organ.
- Small lips are folds located between the large lips and the entrance to the vagina, they can be seen beyond the large lips and be more saturated in color. They are able to get bigger at the moment of sexual attraction.
- Large labia are located on the sides of the genital slit. Their skin is covered with hair on the outside, sweat and sebaceous glands are present on it. Inside they are covered with the thinnest pinkish skin.
- Under the large and small lips there 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 of innocent girls.
Internal organs
These genital organs are located inside the female pelvis, therefore they are called internal:
- Vagina. It is a muscular elastic tube of a certain length.
- The uterus, which is a muscular organ andincluding 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 attachment of the uterus to the tubes.
The walls of the uterus are lined with the endometrium. Under the influence of sex hormones, he is waiting for the egg, which has undergone fertilization, and if it does not appear, it leaves the uterus, causing menstrual bleeding.
The purpose of a woman's womb is to be a container for the fetus, it is where it develops.
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. The mature eggs travel to the fallopian tube, where sperm can await them. If fertilization has occurred, then the egg through the tube enters 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 obtain 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.
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 can greatly facilitate the diagnosisdiseases, to assist in the selection of the right course of treatment.
When an MRI is performed, a person who has taken a horizontal position is placed in the camera of a special tomograph. It is where a certain part of the body is scanned.
In the field of gynecology, safety plays a special role, as he alth problems can have a harmful effect on the development of the baby, even if the woman is not pregnant at the time of the diagnosis.
Top indications for MRI use
MRI is usually prescribed for patients with certain symptoms:
- presence of neoplasms;
- pain in the pelvic area;
- presence of stones or sand in the bladder;
- malfunctions in the development of the genitourinary system;
- trauma in the pelvic area.
The female pelvis needs careful attention and timely investigation.
