Micturition – The process of Urination
On the planet Earth, every living thing excretes waste from their bodies and other sources in various ways. Excretion is a vital process that all living things must go through. It is the process that would be physiological by which the body rids itself of metabolic waste.
Urine is excreted from the body during the micturition process. To remove waste from the body, both animals and humans have an organ system known as the excretory system. Micturition, in other terms, is the process of removing pee from the body. A urine bladder, a urethra, two kidneys, and ureters make up the human excretory system. Urine production and excretion are mostly regulated by the kidneys. The urinary bladder stores the produced pee.
It is of two stages: storage and the voiding stage
Urine is stored in the urinary bladder, a hollow, muscular structure with a balloon-like shape. In a urinary system that would be healthy, the urinary bladder may comfortably hold up to 16 ounces of pee for 2 to 5 hours. The muscles of the circular sphincter stop urine flow. They completely enclose the bladder’s opening into the urethra, which allows urine to exit the body.
The nerves in the bladder are activated when it is full of urine, causing a urogenital desire. Urinary bladder contraction is signaled by the brain. The central nervous system receives a signal from the receptors in the bladder, and in response, now the signal would be sent by the nervous system that causes the bladder to contract. Micturition is the process of passing pee out of the urinary hole at the urethra. The micturition reflex is the name of the underlying brain process.
Problems that would be related to the process of micturition
- Micturition would be influenced by a number of variables. Some would be psychological in character, while some of them may be caused by physical trauma or illness. Here are a few conditions that have an impact on micturition:
- Detrusor instability is a condition in which the detrusor muscle spontaneously contracts. The bladder is contracted by this muscle, which also aids in the micturition process. Urinary incontinence is the outcome of detrusor instability.
- The inability to completely empty the bladder is a defining feature of urinary retention. Sudden or gradual onset is possible. The causes include nerve issues, and urethral blockages, so muscles of the bladder would be weak.
- Spinal Cord Trauma: Damage to the spinal cord, particularly at the level of (T10), can result in urinary incontinence or an overactive bladder.
Regulation of Micturition
- The urinary tract’s nerve supply should still be functional.
- The bladder should have a normal capacity.
- All the muscles which would participate should all have normal muscular tone.
- No part of the urinary system should be blocked from the passage of urine.
- There shouldn’t be any psychological or environmental elements that prevent micturition.
- Normal micturition is aided by the coordinated action of the nervous systems.
Frequently Asked Questions
Question 1: How does micturition can be managed?
Muscles should have a muscle tone normal and the bladder should have a capacity normal.
Question 2: What is micturition?
Excretion of the urine from the bladder of urinary and the Human would have a system called the excretory system through which waste should be eliminated.
Question 3: What is meant by the phase of storage?
The urinary bladder’s ability to store urine defines the storage phase. The muscles of the circular sphincter are in charge of the movement.
Question 4: What is meant by the phase of voiding?
The brain supposedly sends impulses to start peeing until the bladder is empty during the voiding phase.
Question 5: Problems that would be relatable to micturition?
Detrusor instability is a condition in which the detrusor muscle spontaneously contracts. The bladder is contracted by this muscle, which also aids in the micturition process. Urinary incontinence is the outcome of detrusor instability.
Question 6: Which thoracic segment injury causes damage to the micturition process? Why?
Damage at the T10 would lead to bladder overactivity because it causes urine incontinence and the bladder would be overactive.
