Micturition reflex is the neurological pathways involved in urination.
When your bladder fills, the detrusor muscles expand and proprioceptors within the walls of the muscle activate. It sends signals (afferent nerves) that go to your medulla and also to the parasympathetic system in the sacral spinal cord. The signal to the parasympathetic system elicits the response to urinate by relaxing the inner external sphincter and constricting the detrusor muscles. However, first your upper brain is consulted and decides whether it is appropriate to go or not.
If your brain allows, it will elicit the response by inhibiting the sympathetic nervous system and inhibiting the somatic nervous system. The somatic nervous system controls the external sphincter and by inhibiting it, you are relaxing it. The external sphincter is much more powerful than the internal sphincter.
If your brain says no, it will activate the sympathetic nervous system (which relaxes the muscle walls and constricts inner sphincter) and your somatic control continues to constrict the external sphincter.

What is another name for micturition reflex?

What triggers the micturition reflex in the walls of the bladder?
stretch receptors
What does the micturition reflex feel like?
The micturition reflex is the body's automatic response to the feeling of a full bladder and typically manifests as the urge to urinate. This sensation can vary in intensity from mild discomfort to strong urgency depending on the individual and the level of bladder fullness.
What does the parasympathetic nervous system stimulate in the micturition reflex?
The parasympathetic nervous system allows the act of micturition. The sympathetic nervous system inhibits it.
The micturition reflex center is located in the?
sacral segments of the spinal cord
Is the micturition reflex center is located in the pons?
No, the micturition reflex center is located in the sacral region of the spinal cord, specifically at the level of the S2 to S4 segments. This center regulates the process of urination, including the contraction of the bladder and relaxation of the internal urethral sphincter.
What serves as the effector for micturition reflex arc?
An efferent somatic (pudendal nerve) output to the external sphincter which relaxes the external sphincter and causes the urine to flow through the urethra is the effector part of the reflex arc.
Urination is also known as voiding or?
micturition or micturate
Is micturition to empty the bladder?
Yes, micturition is another word for urination.
The act of expelling urine from bladder is called?
I believe it is called "micturition". -JS yes it is micturition..... double checked in medical dictionary thanks -JS from mzippa
How are the micturation reflex and conscious thought involved in urination?
The micturition reflex is an automatic process where the bladder expels urine when it reaches a certain level of fullness, controlled by the autonomic nervous system. Conscious thought can influence urination by allowing an individual to voluntarily start or stop the process, giving them some control over when and where they urinate.
Another name for urination?
