,Section 1: Module 1 – Cellular Neuroscience (Qs 1–35)
Q1. The scientific discipline of neuroscience is best defined as the study of which aspect of
biology?
A) The structure and function of the nervous system
B) The diagnosis and treatment of psychological disorders
C) The hormonal regulation of physiological processes
D) The cellular mechanisms of immune defense
Answer: A
Neuroscience is an interdisciplinary field dedicated to understanding the nervous system's
anatomy, physiology, development, and pathology.
Q2. Which two primary divisions constitute the organizational framework of the nervous
system?
A) Somatic and autonomic divisions
B) Central and peripheral divisions
C) Sympathetic and parasympathetic divisions
D) Afferent and efferent divisions
Answer: B
The nervous system is fundamentally organized into the central nervous system (brain and
spinal cord) and the peripheral nervous system.
Q3. Which part of the neuron is primarily responsible for receiving signals from other
neurons?
A) Axon
B) Dendrite
,C) Soma
D) Myelin sheath
Answer: B
Dendrites are tree-like extensions that increase the surface area of the neuron and are the
primary sites where signals are received from other neurons via synapses.
Q4. What is the primary function of the myelin sheath?
A) To generate and conduct electrical impulses
B) To receive neurotransmitters from other neurons
C) To protect and insulate axons, increasing conduction speed
D) To regulate the concentration of ions inside the neuron
Answer: C
The myelin sheath is a fatty, multilayered covering that acts as an electrical insulator,
preventing ion leakage and increasing the speed at which action potentials propagate via
saltatory conduction.
Q5. Which structure is NOT part of the central nervous system (CNS)?
A) Brain
B) Spinal cord
C) Ganglion
D) Medulla oblongata
Answer: C
A ganglion is a cluster of nerve cell bodies located outside the CNS, making it a component
of the peripheral nervous system.
Q6. Which type of glial cell is responsible for forming the blood-brain barrier (BBB)?
A) Oligodendrocytes
B) Microglia
, C) Astrocytes
D) Ependymal cells
Answer: C
Astrocytes are star-shaped glial cells that have end-feet which wrap around blood vessels in
the brain, maintaining the integrity of the blood-brain barrier.
Q7. The production of cerebrospinal fluid (CSF) occurs in which structure?
A) Arachnoid villi
B) Choroid plexus
C) Pia mater
D) Dura mater
Answer: B
The choroid plexus is a network of specialized ependymal cells and capillaries that
produces CSF.
Q8. Which glial cell type is responsible for myelinating axons in the peripheral nervous
system?
A) Oligodendrocytes
B) Schwann cells
C) Astrocytes
D) Microglia
Answer: B
Schwann cells myelinate axons in the PNS, while oligodendrocytes perform this function in
the CNS.
Q9. What is the resting membrane potential of a typical neuron?
A) -70 mV
B) -55 mV
