Which of the following sphincters cause the release of the urine?(a) C

1.	Which of the following sphincters cause the release of the urine?(a) Cardiac sphincter(b) Pyloric sphincter(c) Urethral sphincter(d) Oesophageal sphincterI had been asked this question by my school principal while I was bunking the class.The question is from Disorders in Excretory System in division Excretory Products and Elimination of Biology – Class 11
Answer» Right answer is (c) Urethral sphincter Best explanation: Urethral sphincter CAUSES the RELEASE of URINE to the outside of the body. This process starts when the central nervous system passes on the motor MESSAGES to the smooth muscles of the bladder. This signal INITIATES their contraction. Simultaneously, relaxation of the urethral sphincter takes place which causes the release of the urine.
