Question:

Micturition reflex is

Options:

1. Hormonal mechanism to control Micturition
2. Neural mechanism to control Micturition
3. Local mechanism to control Micturition
4. Both B and C

Solution:

The micturition reflex is a neural mechanism to control urination. The micturition reflex is a complex neural pathway that involves both the autonomic and somatic nervous systems. When the bladder is full, stretch receptors in the bladder wall send signals to the spinal cord, which in turn sends signals back to the bladder and the urethra to initiate the micturition reflex. The parasympathetic nervous system stimulates the bladder to contract, while the external urethral sphincter relaxes under voluntary control, allowing urine to flow out of the body. While hormones do play a role in regulating urine production and the overall function of the urinary system, they are not directly involved in the micturition reflex. The local mechanism also plays a role in regulating urine production, but it is not the mechanism responsible for initiating urination.
