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.
