All of the statements are correct. Stretch receptors in the bladder wall send afferent signals to the sacral cord, which triggers the micturition reflex. In response, parasympathetic motor neurons cause the detrusor muscle to contract, while the internal urethral sphincter relaxes subconsciously, and the external urethral sphincter can be consciously relaxed to allow urine to be expelled.
