EEG 200 EXAM QUESTIONS WITH 100%
CORRECT ANSWERS/NEWEST UPDATE 2025
The basic functional unit of the nervous system is the neuron. What is the major
function of this cell type? - CORRECT ANSWER- to generate and transmit nerve
impulses.
Microglia - CORRECT ANSWER- phagocytosis of debris (dead cells, bacteria, etc.)
Oligodendrocytes - CORRECT ANSWER- form myelin around axons in the CNS
Astrocytes - CORRECT ANSWER- support the neurons; may serve nutritive function
and help regulate the chemical environment of the neuron.
Ependymal - CORRECT ANSWER- Line cavities of the brain ( and spinal chord); aid in
circulation of cerebrospinal fluid.
Schwann Cell - CORRECT ANSWER- PNS glial cell that forms myelin
Satellite Cell - CORRECT ANSWER- PNS glial cell that surrounds dorsal root ganglion
neurons
Central Nervous system - CORRECT ANSWER- The brain and Spinal cord collectively.
Neuroglia - CORRECT ANSWER- Specialized supporting cells in the CNS
Synapse - CORRECT ANSWER- Junction or point of close contact between neurons
Tract - CORRECT ANSWER- A bundle of nerve processes in the CNS
Interneuron - CORRECT ANSWER- Neuron serving as part of the conduction pathway
between sensory and motor neurons
Peripheral Nervous System - CORRECT ANSWER- Ganglia and spinal and Cranial
Nerves
Ganglion - CORRECT ANSWER- Collection of cell bodies found outside the CNS
Efferent Neuron - CORRECT ANSWER- Nueron that conducts impulses away from the
CNS to muscles and glands
, Afferent Neuron - CORRECT ANSWER- Neuron that conducts impulses towards the
CNS from the body Periphery
Neurotransmitters - CORRECT ANSWER- Chemicals released by neurons that
stimulate or inhibit other neurons or effectors
Axon Hillock - CORRECT ANSWER- region of the cell body from which the axon
originates
Axon Terminal - CORRECT ANSWER- Secretes Neurotransmitters
Dendrite - CORRECT ANSWER- Receptive region of a neuron
What is a nerve? - CORRECT ANSWER- a bundle of axons wrapped in connective
tissue. Extends to andlor from the CNS or body viscera or peripheral structures.
Endoneurium - CORRECT ANSWER- surrounds axons
Perineurium - CORRECT ANSWER- surrounds a bundle of axons
Epineurium - CORRECT ANSWER- surrounds all of the axons contributing to a nerve
What is the function of the connective tissue wrappings found in a nerve? - CORRECT
ANSWER- to protect and insulate the delicate nerve fibers
Mixed Nerve - CORRECT ANSWER- Nerve containing both sensory (afferent) and
motor (efferent) fibers
Sensory Neurons are multipolar, unipolar or bipolar? - CORRECT ANSWER- Sensory
Neurons are unipolar
Motor and interneurons are mostly? - CORRECT ANSWER- motor and interneurons are
mostly Multipolar
Frontal lobe - CORRECT ANSWER- Primary Motor Cortex, Broca's Area
Parietal Lobe - CORRECT ANSWER- Primary Sensory Cortex
Temporal Lobe - CORRECT ANSWER- Auditory Cortex, Olfactory Cortex
