Which of the following initiates the voluntary signal given by CNS?a)L...
Stretching of the urinary bladder
Stretching of the urinary bladder initiates the voluntary signal given by the central nervous system (CNS) to control the process of micturition, or urination.
Explanation:
- When the urinary bladder fills with urine, it stretches and activates stretch receptors in the bladder walls.
- These stretch receptors send signals to the CNS, specifically to the brain and spinal cord, indicating that the bladder is full.
- In response to this signal, the CNS initiates the voluntary process of micturition.
- The brain then sends signals to the muscles of the bladder (detrusor muscle) to contract and the muscles of the external urethral sphincter to relax.
- This coordinated muscle action allows for the controlled release of urine from the bladder through the urethra.
- The stretching of the bladder and the subsequent signaling to the CNS play a crucial role in the control of urination.
In conclusion, the stretching of the urinary bladder is a key factor in initiating the voluntary signal given by the CNS to regulate the process of urination.
