pelvic organs are in the anatomical space defined by the bones of the pelvis, and include the ureter, bladder, rectum, prostate, seminal vesicle, vagina, uterus and ovaries.
Rectum
pelvic organs of women and men include that part of the colon, which is the ultimate.It accumulated and excreted waste digestion.In the adult human colon length is 15 centimeters and a diameter equal to two to eight centimeters.Behind her is the coccyx and sacrum, the front pelvic organs: in women - the bladder, vagina and uterus;The men - seminal vesicles with ampoules ejaculatory streams, prostate and bladder.
In fact, the rectum is not, it forms the sagittal plane two bends, the first - Crusade (corresponds to the configuration of the sacrum), the second - the crotch (located in front of the coccyx, convex forward).In the frontal plane of bending of the rectum are impermanent.
Bladder
Located behind the pubic symphysis and the front surface is also drawn to it, separated from it by a loose fiber located in the space behind the pubic area.At the top of its filling of the bladder, coming into contact with the anterior abdominal wall protrudes above the symphysis.
Most of the pelvic organs of women and men on the location in the pelvic area are slightly different from each other.This feature is clearly seen by the location of the bladder, in particular its rear surface: women - in contact with the front wall of the vagina and uterus, and the bottom of the bladder in the female body in contact with the urogenital diaphragm.Men - adjacent to the seminal vesicles and vas ampoules flows, as well as to the rectum, the bottom adjacent to the prostate.To the bladder (the upper part) adjacent pelvic organs: the woman - the womb, a man - a loop of the small intestine.
peritoneum covering the bladder around, except for the lower part, the transition of women and on the uterus, in men - to the rectum.Since it is connected to the navel median umbilical ligament, the lower part of the small pelvis ligaments: women - pubic-cystic men - prostate-pubic.
female pelvic organs
Ovary
This female sex gland is paired organs.In the ovaries mature and develop egg, female sex hormones are formed, which subsequently enter the lymph and blood.Ovary has a pinkish color, ovoidal somewhat flattened front.The surface of the ovary becomes convex back (free) edge.Mesenteric front edge which is attached to the ovarian mesentery, where there is a deepening trough - ovarian gate through which the ovary consists of nerves and arteries, and lymph vessels come with veins.
Near each ovary are rudimentary education: vesicular pendants with paroophoron, an appendage of the ovarian duct primary kidney tubules and its remnants.
appendage ovarian nestled among leaves of the mesentery of the fallopian tube, lateral and rear of the ovary.It consists of a longitudinal duct of the epididymis, and convoluted, flowing into it tubules - transverse bore (blind ends are converted to the gate of the ovary).
paroophoron (appendage appendage) is the formation of small size, as occurs in the mesentery of the fallopian tube, near the end of the pipe ovary.It consists of several disjunct between a blind tubules.
uterus
muscular, pear-shaped organ unpaired, in the anteroposterior direction somewhat flattened.It is located in the pelvic cavity, in the middle part of it, in front of the rectum, behind the bladder.The uterus is customary to distinguish several parts:
- bottom of the uterus: the uterus of a convex shape, protruding slightly above the confluence of the fallopian tubes and goes to her body;
- body of the uterus: representing more (middle) part of the body has the shape of a cone.Below narrows and becomes a rounded part - cervix.The place of transition narrows slightly and called the isthmus of the uterus;
- cervix: the lower part of it juts out into the cavity of the vagina (vaginal portion of the cervix), and the upper part lies above the vagina - nadvlagalishnyaya of the neck on it shows the opening of the uterus (cervix), which leads from the vagina into the cervix (its channel)and has an extension in its cavity.
Vagina
unpaired hollow body extends from genital slit to the uterus, and has a tubular shape, somewhat curved rear (longitudinal axis of the vagina with the axis of the uterus forms an obtuse angle slightly greater than 90 degrees).The upper end originates from the cervix, then goes down to the lower end of which it opens the opening of the vagina and passes through the urogenital diaphragm.The vagina has a length of about ten centimeters, a wall thickness of about three millimeters.
Since the pelvic organs of women and men are placed in a small volume, the nature of the pathological changes may have some influence on the function of the adjacent pelvic organs.
pelvic organs male
Seminal vesicle
It paired organ, located behind and to the side of the bladder from the vas flow laterally, from the top of the prostate gland.It is a secretory organ.There is a front (facing the bladder) and rear (adjacent to the rectum) surface.The length of the body of the pelvis about five centimeters, a width of two and a thickness of one centimeter.In terms of looks like interconnected bubbles.
excretory duct connected to the vas, where they form the ejaculatory duct.The length of it about two centimeters, width clearance in the beginning - one millimeter, from the urethra - 0.3 millimeters.
Prostate
Muscle-ferrous unpaired organ.In the process of life highlights the secret that is part of semen.Located in front of the lower part of the pelvic organs on the urogenital diaphragm, below the bladder.Through it passes the initial part of the urethra (it is the reason for it), and the two ejaculatory ducts.
across up to four centimeters, a longitudinal dimension (verhnenizhny) is three centimeters thickness (anteroposterior size) - two centimeters.The substance of its thick consistency grayish-red.
