Portage Learning A&P II Module 1 Nervous System Exam Prep – 100+ Questions & Answers | CNS, PNS, Neurons, Neuroglia, Action Potentials, Synapses & Reflex Arcs | Anatomy & Physiology II Test Bank Review 2026

Master the foundational concepts of the nervous system with this comprehensive Portage Learning Anatomy & Physiology II Module 1 study guide featuring more than 100 exam-style questions and answers covering nervous system organization, neuron structure and function, neuroglial cells, membrane potentials, action potentials, neurotransmission, spinal cord anatomy, reflex pathways, and autonomic nervous system regulation. This resource is specifically designed for students enrolled in Anatomy & Physiology II, Nursing, Allied Health, Pre-Medical, Health Science, and healthcare-related programs seeking to strengthen their understanding of neurophysiology and improve examination performance. The material provides extensive coverage of the structural and functional organization of the nervous system, including the Central Nervous System (CNS) and Peripheral Nervous System (PNS). Students will learn the roles of the brain, spinal cord, cranial nerves, spinal nerves, sensory pathways, motor pathways, afferent divisions, efferent divisions, somatic nervous system, autonomic nervous system, sympathetic division, and parasympathetic division. Special emphasis is placed on how the nervous system integrates sensory information, coordinates responses, regulates organ systems, and maintains homeostasis throughout the body. A major focus of the guide is neuron anatomy and neurophysiology. Topics include dendrites, cell bodies, axons, axon terminals, axon hillocks, myelin sheaths, Nodes of Ranvier, ganglia, nuclei, tracts, nerves, sensory neurons, motor neurons, interneurons, multipolar neurons, bipolar neurons, and unipolar neurons. Students will gain a detailed understanding of neuronal communication, impulse conduction, neurotransmitter synthesis, neurotransmitter release, synaptic transmission, and the cellular mechanisms responsible for rapid information processing within the nervous system. The study guide also delivers in-depth coverage of membrane physiology and electrical signaling. Key concepts include resting membrane potential, depolarization, repolarization, after-hyperpolarization, sodium-potassium pumps, ion gradients, voltage-gated channels, action potentials, electrochemical signaling, impulse propagation, and neuronal excitability. Students will learn how ionic movement across cell membranes generates nerve impulses and enables communication between neurons, muscles, and glands. Additional emphasis is placed on neuroglial cells and nervous system support structures. Topics include Schwann cells, satellite cells, astrocytes, oligodendrocytes, microglial cells, ependymal cells, cerebrospinal fluid regulation, blood-brain barrier function, axonal insulation, neuronal protection, and nervous tissue maintenance. The guide also explores spinal cord anatomy, dorsal roots, ventral roots, dorsal root ganglia, gray matter, white matter, spinal nerves, posterior horns, anterior horns, sensory pathways, motor pathways, and reflex arc physiology. Students will further review neurotransmitters such as acetylcholine and dopamine, neuromuscular junction physiology, muscle contraction mechanisms, reflex actions, stretch reflexes, muscle spindles, and autonomic nervous system responses. These concepts form the foundation for advanced studies in neuroscience, pathophysiology, pharmacology, neurology, and clinical healthcare practice. This resource aligns with curricula taught in Portage Learning A&P II, Human Anatomy and Physiology, Neurobiology, Nursing, Allied Health, Exercise Science, Kinesiology, Medical Assisting, Physician Assistant Studies, and Pre-Medical programs. The question-and-answer format promotes active recall, concept mastery, critical thinking, and examination success while covering the high-yield nervous system concepts most frequently assessed in anatomy and physiology courses.
