Bladder - a hollow body with ploskookrugloy shape and is positioned in the pelvic cavity, directly behind the pubic symphysis.It is based on the muscle.The shape, size change during bladder filling and emptying.Filled with a pear-shaped body, a broad part of the converts back and up, the narrow - forward and downward.To empty the bladder characterized saucer shape, a confluence of all the walls.Body Capacity of 750 cubic cm.It is different in men and women.
bladder.Anatomy
body consists of parts that go into each other.The main part of the body is a bubble.Verhneperednyaya top of the wall forms, which clearly stands out when it is full.Bladder up forms medial ligament navel, which is obliterated urachus.The bottom of the bubble educated his back, which in men is directed toward the rectum and the vagina in women.Anteroinferior portion of the neck forms a body, here is the opening of the urethra (the interior).
core walls of the bladder smooth muscle tissue type, its cavity is lined with a membrane, which has a slimy character.The body partially covered by a connective tissue sheath.The thick muscular layer consists of three layers: the outer, middle, inner.The outer layer begins from the pubic symphysis, goes back towards the neck, then it goes around and ends at the top of the organ.He gives recto-cystic muscles to the corresponding layer of the rectum in women formed vesico-cervical muscle.The main body of the structure is the middle muscular layer.It has a circular layout.In cervical muscle pulp it forms the internal urethra.The most thin layer is the internal, which is characterized by multi-directional course of fibers.It is well developed in the bottom of the body.
The bladder has a well-developed mucous layer.He is represented by a thick stratified squamous epithelium.The mucosa includes submucosa, which is rich in fibrous tissue connecting the nature and riddled with thick fibers.Because of such a structure formed creases that follow the contours of the muscle layer.But they are stretched during filling.
structure of the bladder corresponds to its primary function - the accumulation and subsequent excretion of urine.In it, there are three holes.The first two represented the mouths of the ureters, the third - the opening of the urethra.They are located in the urinary triangle, which is the most variable and fixed portion of the body.There mucosa directly related to the muscle layer.
mucosal layer of the back of the mouth of the urethra forms a tongue bladder, which goes into the ridge.The peritoneum covers part of the side surfaces of the body and completely verhnezadnyuyu part.It moves from the rear surface to the uterus in women and in men - on the straight intestine.The front part is directly under the pubic symphysis, while filling it rises above this level.By the bottom of the body of the male part of the adjacent prostate gland, seminal vesicles, vas deferens part.The women at this level is the cervix, vaginal wall.
Lower Division side wall of the body, which is located preperitoneal, adjacent to the bottom of the pelvis were full - to the obturator muscle in women is the round ligament, the vas deferens in men.
urinary organ is an important part of the urinary system, which is essential for normal functioning of the whole organism.In violation of its functions are disrupted all the structures of the human, so it is important timely diagnosis and prevention of diseases.
