Pathophysiology of Vomiting Explained in Nepali | Mechanism, Centers & Clinical Points | Med Student

Vomiting is a common clinical symptom encountered in hospitals, wards, and exams. For Nepali medical students, understanding the pathophysiology of vomiting is essential for MBBS, nursing, and OSCE exams, as well as for clinical reasoning during patient management. In this video, we explain vomiting in a simple, exam-oriented manner. You will learn about the central vomiting center located in the medulla oblongata, which coordinates the complex reflex involving the gastrointestinal tract, diaphragm, abdominal muscles, and autonomic nervous system. We also discuss the chemoreceptor trigger zone (CTZ) in the area postrema, which is highly sensitive to toxins, drugs, and metabolic disturbances. The video highlights the afferent pathways that stimulate vomiting: Gastrointestinal tract via vagal and sympathetic fibers (chemical and mechanical stimuli) Vestibular system via cranial nerves VIII (motion sickness) Cerebral cortex (psychogenic stimuli, fear, pain, odors) Chemoreceptor trigger zone (blood-borne toxins, uremia, drugs) We also explain the efferent pathways: coordinated contractions of the diaphragm, abdominal muscles, and relaxation of the lower esophageal sphincter. Clinical correlations include nausea and vomiting in gastroenteritis, pregnancy, motion sickness, raised intracranial pressure, drugs, and toxins. High-yield exam points cover the neurotransmitters involved — dopamine, serotonin (5-HT3), histamine (H1), acetylcholine (M1), and substance P (NK1) — which are targets for antiemetic drugs. This guide is ideal for MBBS students, nursing students, and health assistants in Nepal preparing for exams, OSCEs, and clinical rotations. 🔖 Tags vomiting pathophysiology, nausea and vomiting, Nepali medical student, MBBS Nepal physiology, vomiting center, chemoreceptor trigger zone, afferent and efferent pathways, neurotransmitters vomiting, antiemetics targets, motion sickness mechanism, gastrointestinal reflex, OSCE physiology, medical education Nepal, NMC exam preparation McQ Live mbbs , Model question mbbs Welcome to the *Cee Cracker* YouTube channel, your ultimate guide to acing the *CEE* (Common Entrance Examination) for MBBS students in Nepal!
