Study Notes
Bladder Filling
- As the bladder fills to about 150-250 mL in an adult, the stretch receptors in the bladder wall signal the brain, leading to the sensation of urinary urge.
Nephrons
- The main function of nephrons in the urinary system is to filter waste and excess fluids from the blood, regulating electrolyte levels and maintaining acid-base balance.
Micturition
- Factors affecting micturition include:
- Neurological factors, such as the ability of the brain to transmit signals to the bladder
- Muscular factors, including the contraction and relaxation of the detrusor muscle
- Hormonal factors, which influence the bladder's ability to store urine
- Voluntary factors, such as the individual's decision to urinate
Detrusor Muscle
- The detrusor muscle plays a crucial role in the act of micturition, as its contraction allows the bladder to empty and the urine to flow out.
Urinary Elimination Assessment
- The specific assessment technique mentioned in the text for urinary elimination is the measurement of bladder capacity, which helps to evaluate the individual's ability to store and eliminate urine.
