,This comprehensive exam assesses foundational and applied knowledge essential for understanding the
human nervous system in anatomy and physiology. The purpose is to evaluate students' mastery of nervous
tissue classification, neuron anatomy, glial cell functions, brain region structures and roles, spinal cord
organization, nerve distribution, and sensory-motor mechanisms. The multiple-choice and scenario-based
structure emphasizes critical thinking, clinical application, and professional decision-making skills. Questions
range from basic theory to real-world clinical scenarios requiring analysis of neurological function, regulatory
compliance in healthcare settings, and ethical considerations in patient care. Success on this exam
demonstrates readiness for advanced clinical practice and demonstrates competency in nervous system
anatomy and physiology necessary for healthcare professionals.

Question 1
What are the different types of nervous tissue?
A. Axons and dendrites
B. Neurons and Glia
C. Myelin and Schwartz cells
D. Synapses and neurotransmitters
🟢 B. Neurons and Glia
🔴 RATIONALE: Nervous tissue consists of two main types: neurons (nerve cells that transmit signals) and glia
(supporting cells including astrocytes, microglia, oligodendrocytes, and Schwann cells). This is the fundamental
classification of nervous tissue.
Question 2
, What makes up the Nervous System?
A. Brain and spinal cord only
B. Central nervous system and peripheral nervous system
C. Neurons and myelin sheaths
D. Sensory and motor neurons
🟢 B. Central nervous system and peripheral nervous system
🔴 RATIONALE: The nervous system is composed of the central nervous system (CNS - brain and spinal cord)
and the peripheral nervous system (PNS - all nerves outside the CNS). This is the primary organizational
division.
Question 3
What is an Astrocyte?
A. A neuron that transmits sensory information
B. The most abundant glia cell that makes up the blood-brain barrier
C. A cell that produces neurotransmitters
D. The myelin sheath producer in the PNS
🟢 B. The most abundant glia cell that makes up the blood-brain barrier
🔴 RATIONALE: Astrocytes are the most abundant glial cells, make up the blood-brain barrier, and promote
nerve growth. They are essential for CNS support and protection.
