Question
The micturition reflex involves impulses from the bladder traveling to which region of the spinal cord?
Multiple Choice
- Lumbar
- Coccygeal
- Sacral
- Thoracic
Solution
The micturition reflex primarily involves impulses from the bladder traveling to the sacral region of the spinal cord. This is because the sacral segments of the spinal cord (specifically S2 to S4) are responsible for the innervation of the bladder and play a crucial role in controlling the act of urination. The pathways involved in the micturition reflex facilitate the contraction of the bladder and the relaxation of the external urethral sphincter, allowing for the release of urine.
In summary, for the question regarding where the micturition reflex impulses travel in the spinal cord, the correct answer is Sacral.
