Q1. The superior hypogastric plexus is primarily a continuation of which abdominal autonomic network?
- Aortic plexus
- Cardiac plexus
- Brachial plexus
- Pulmonary plexus
Q2. Which nerves carry predominantly sympathetic fibers from the superior hypogastric plexus toward the inferior hypogastric plexuses?
- Pelvic splanchnic nerves
- Hypogastric nerves
- Pudendal nerves
- Obturator nerves
Q3. Which nerves provide an additional sympathetic contribution directly to the inferior hypogastric plexus?
- Phrenic nerves
- Sacral splanchnic nerves
- Pelvic splanchnic nerves
- Greater splanchnic nerves
Q4. Which statement correctly distinguishes pelvic splanchnic nerves from sacral splanchnic nerves?
- Pelvic splanchnic nerves are sympathetic, while sacral splanchnic nerves are parasympathetic
- Pelvic splanchnic nerves are parasympathetic, while sacral splanchnic nerves are sympathetic
- Both arise from the lumbar plexus
- Both are exclusively somatic motor nerves
Q5. Which named plexus derived from the inferior hypogastric plexus supplies the urinary bladder?
- Vesical plexus
- Cardiac plexus
- Brachial plexus
- Celiac plexus
Q6. Which derivative of the inferior hypogastric plexus is closely associated with the prostate?
- Renal plexus
- Pulmonary plexus
- Prostatic plexus
- Hepatic plexus
Q7. Which autonomic pathway is especially important for detrusor contraction during urination?
- Obturator somatic pathway
- Femoral somatic pathway
- Sacral splanchnic sympathetic pathway
- Pelvic splanchnic parasympathetic pathway
Q8. Parasympathetic fibers associated with the inferior hypogastric plexus contribute to which sexual response?
- Erection
- Extension of the hip
- Emission
- Somatic contraction of quadriceps
Q9. Sympathetic fibers distributed through the pelvic autonomic plexuses have an important role in which male reproductive function?
- Initiation of erection
- Voluntary contraction of the external anal sphincter
- Emission
- Spermatogenesis
Q10. Why is the inferior hypogastric plexus described as a mixed autonomic plexus?
- It contains only sympathetic fibers
- It contains only somatic motor and sensory fibers
- It contains only parasympathetic fibers
- It contains both sympathetic and parasympathetic fibers
