Physiology for Physician Assistant Programs
Exam Bank
Course Introduction
This course provides an in-depth exploration of human physiology tailored for physician assistant students, focusing on the fundamental mechanisms that govern the function of the bodys organ systems. Emphasizing the integration of cellular processes and organ system regulation, topics include neurophysiology, cardiovascular physiology, respiratory dynamics, renal function, gastrointestinal physiology, endocrine control, and musculoskeletal interactions. The curriculum bridges basic scientific principles with clinical applications, preparing students to understand physiological responses to disease states, therapeutic interventions, and clinical assessments. Critical thinking and problem-solving skills are developed through case studies, laboratory exercises, and interactive discussions relevant to patient care.
