Physiology of urinary elimination → -void, urinatinon, micturition → -volume of 250-450 ml pressure rises → -cerebral cortex is the final control Process of micturition → 1. urine collects in bladder → 2. pressure stimulates special stretch receptors in bladder wall → 3. stretch receptors transmit impulses to spinal cord voiding reflex center → 4. internal sphincter relaxes, stimulating the urge to void → 5. If appropriate, the conscious portion of the brain relaxes the...
