yes and no. sometimes you feel as if your bladder cannot hold as much urine as usual, right? But it does not mean that your bladder has shrunk. It is simply a symptom that means you may be having bladder problems. consult a doctor if you feel as if it has "shrunk".
Yes, this is called referred pain from the bladder being over stretched.
Urinary Bladder
Yes, you could say so. These cells appear to be square with a rounded surface when the organ or the tube in which they are found is not stretched. When the organ or tube is stretched (e.g. when the bladder is filled with urine), the tissue is compressed and the cells become stretched and more flat.
Transitional epithelium is the epithelial tissue that has cells capable of changing shape when stretched (such as when the bladder is full) or contracted (when the bladder is empty). This type of epithelium allows for tissue expansion without losing its integrity.
The human bladder can be stretched through exercise so that a person may hold their urine for longer. This practice, however, is dangerous as holding onto the urine for longer may lead to urinary tract infections as the tracts have to be routinely flushed to maintain the correct flora.
urinary retention is when the urinary bladder is unable to empty. This can be due to either an acute or chronic condition. The bladder muscle gets stretched beyond the point of having enough strength to contract and allow the bladder to empty. Sometimes common medications contribute to the problem.
The trigone is a smooth triangular region of the internal urinary bladder formed by the two ureteral orifices and the internal urethral orifice. The area is very sensitive to expansion and once stretched to a certain degree, the urinary bladder signals the brain of its need to empty. The signals become stronger as the bladder continues to fill.
The receptors for a full bladder are classified as mechanoreceptors. These receptors are sensitive to the stretching of the bladder wall that occurs as it fills with urine, sending signals to the brain indicating the need for voiding.
Because your bladder is only designed to hold so much. Once it reaches a point where the tissues are stretched too far, the nerve endings in the bladder send pain signals to your brain. The muscle that is part of the layered bladder wall, the detrusor muscle, starts to contract, increasing the pressure. At that point, break off what you're doing and go!
The trigone is a smooth triangular region of the internal urinary bladder formed by the two ureteral orifices and the internal urethral orifice.The area is very sensitive to expansion and once stretched to a certain degree, the urinary bladder signals the brain of its need to empty. The signals become stronger as the bladder continues to fill.Embryologically, the trigone of the bladder is derived from the caudal end of mesonephric ducts, which is of mesodermal origin (the rest of the bladder isendodermal). In the female the mesonephric ducts regresses, causing the trigone to be less prominent, but still present.
The pelvic floor normally holds the uterus and the bladder in position above the vagina. When the pelvic floor becomes stretched/damaged, these organs can sag into the vagina, sometimes bulging out.
It means that it is enlarged for some reason. It could mean that you really need to empty it and haven't. Anything that blocks the urethra from allowing the urine to flow, such as an enlarged prostate or kidney stones, can result in a distended bladder.Another symptom of a distended bladder is a delay in urination. A person may need to strain in order to begin the flow of urine.
