Micturition is another term for

A. High HDL: low LDL: HDL ("good cholesterol") helps remove excess cholesterol, while LDL ("bad cholesterol") contributes to atherosclerosis. This ratio lowers cardiovascular risk.
B. High LDL: low HDL: Unhealthy. Promotes plaque buildup in arteries, increasing cardiovascular risk.
C. High LDL: low chylomicron: Still unhealthy due to elevated LDL, regardless of chylomicron level.
D. High SFA: low HDL: Saturated fatty acids (SFAs) increase LDL and lower HDL—this is an unhealthy lipid profile.
E. High chylomicron: low LDL: Chylomicrons transport dietary triglycerides but are not indicative of long-term lipid health.

A. It is an autonomic reflex mediated predominantly by parasympathetic nerve fibers: Erection is primarily driven by parasympathetic stimulation (S2–S4), which causes vasodilation of penile arteries and engorgement of erectile tissue.
B. It is an autonomic reflex mediated predominantly by sympathetic nerve fibers: Sympathetic fibers are involved in ejaculation and detumescence, not erection initiation.
C. It is a somatic reflex mediated predominantly by parasympathetic nerve fibers: Erection is not mediated by somatic (voluntary) control.
D. It is a somatic reflex mediated predominantly by sympathetic nerve fibers: Both components are incorrect—erection is not somatic and not sympathetic.
E. It is an exclusively voluntary action mediated by the cerebral cortex: Erection can be influenced by psychological stimuli, but the physiological mechanism is autonomic, not voluntary.
