Urination, Micturition

Urination (Urination, Micturition) is a physiological process that allows the body to get rid of unnecessary metabolic products such as urea, creatinine, and other substances that need to be removed from the body. This process is controlled by the central nervous system and occurs with the participation of the bladder, urethra and special muscles.

Urination begins by filling the bladder with urine, which comes from the kidneys. When filled, the bladder begins to stretch, which leads to stimulation of receptors in its walls. These receptors transmit signals to the central nervous system, which activates parasympathetic neurons that innervate the detrusor muscle, the muscle that expels urine.

Activation of these neurons causes contraction of the detrusor muscle and relaxation of the spinal cord muscles that control the external urethral sphincter. In this case, simultaneous relaxation of the voluntary external urethral sphincter and contraction of the detrusor occurs, which leads to emptying of the bladder.

In addition, urination can be a controlled process that depends on conscious control. This control is exerted through the cortical structures of the brain, which influence the activity of the spinal cord and the muscles of the spinal cord. When a person wants to go to the toilet, he can consciously control the muscles that control the urethra, which allows him to delay or initiate the process of urination.

Urinary problems can also be impaired as a result of various medical conditions, such as urinary tract infections, acute urinary retention, urinary incontinence, etc. Such urinary problems can lead to serious health problems, so it is important to see a doctor at the first sign of urinary problems.

Overall, urination is an important physiological process that allows the body to get rid of waste and maintain a healthy urinary system. Proper functioning of the urinary system is essential for maintaining overall health of the body.



Urination is the process of removing urine from the body. It consists of periodic stretching and contraction of the smooth muscle bladder, which is located at the beginning of the genitourinary organs in men, and at the end in women.

In women, the urinary tube is called the urethra and is separated from the vagina and uterus by a septum



Urination/Micturitio

Micturatio or Urino is the periodic separation of urine from the bladder until this organ reaches its size. The bladder begins to fill with urine and random drops are released under its pressure. These same drops cause stretching of the bladder walls. In this condition, a person produces urine in different quantities. When the bladder is full and there is no emptying, the amount of urine in it increases due to stretching of the walls. Changes in fluid pressure cause the detrusor to contract. Excretion of urine during urination



The urinary reflex (in women it has another name - micturia) is one of the most physiological processes in the body. It allows you to get rid of excess fluid dissolved in the blood or remaining after digestion of food. If a person is healthy, the frequency of his urinary urges is constant, that is, from 4 to 5 per day. A person also understands exactly when it’s time to go to the toilet. However, urinary problems can occur due to various medical conditions. Let's look at the most common pathologies of the urinary tract. Every woman can have complications during genitourinary intercourse. About 25% of patients of reproductive age encountered this problem at least once. 90% of them have one-time difficulties - they can be solved at home without the help of a doctor. 15% of women experience regular disturbances during urination. In 0.3–1% of cases, surgical intervention is indicated.
