This document lists 29 important questions of physiology for second year MBBS students, as outlined by Dr. Mudassar Ali Roomi. The questions cover topics such as neurotransmitters, sensory receptors, reflexes, pain pathways, vision, hearing, hormone mechanisms of action, cerebellar function, sleep, epilepsy, the autonomic nervous system, basal ganglia, memory, kidney function regulation, and acid-base balance. The questions are meant to provide an overview of key physiological concepts and systems for medical students to understand.
