Autonomic Nervous System: Anatomy and Pharmacology

This topic explores the structure, function, and pharmacology of the sympathetic and parasympathetic divisions of the autonomic nervous system. Zambian tertiary students in medicine, physiology, and nursing will gain a deep understanding of the thoracolumbar outflow, craniosacral outflow, and the neurotransmitters involved (acetylcholine, norepinephrine). The content extends to clinically relevant pharmacology, including drugs that act as agonists or antagonists at adrenergic and cholinergic receptors, and their applications in conditions like hypertension, asthma, and shock. This knowledge is fundamental for interpreting autonomic reflexes, understanding drug side effects (e.g., dry mouth from antimuscarinics), and managing autonomic dysfunction. It is a core component of physiology and pharmacology syllabi at Zambian universities and colleges, directly assessed in examinations and applied daily in clinical decision-making during internships and professional practice.
