KIERSTEN'S NU110 EXAM QUESTIONS
AND ANSWERS GRADED A+ 2025/2026
What are the two divisions of the nervous system? - ANS CENTRAL Nervous System (CNS) and
PERIPHERAL Nervous System (PNS)
What is included in the Central Nervous System (CNS)? - ANS Brain and spinal cord
What is included in the Peripheral Nervous System (PNS)? - ANS Cranial nerves and spinal
nerves
What are the divisions of the Peripheral Nervous System (PNS)? - ANS The SOMATIC nervous
system and AUTONOMIC nervous system
Effector - ANS Any tissue or organ that CARRIES OUT A COMMAND from the nervous system
Autonomic Nervous System - ANS INVOLUNTARY Peripheral Nervous System (PNS) -
smooth/cardiac muscle, glands
Somatic Nervous System - ANS VOLUNTARY Peripheral Nervous System (PNS) - SKELETAL
MUSCLE
Neurons - ANS Functional cells of the nervous system

, Dendrites - ANS Neuron fibers that CONDUCT impulses TO the cell body
Axons - ANS Neuron fibers that CONDUCT impulses AWAY from the cell body
Receptors - ANS RECEIVE a STIMULUS that begins a neural pathway
Myelin - ANS WHITE FATTY substance that covers the axon in a SHEATH, INSULATES and
PROTECTS the axon, SPEEDS nerve impulses
What is the difference between white and gray matter - ANS White matter is covered in
myelin
Types of Neurons - ANS Sensory neurons, motor neurons, and interneurons
Sensory neurons - ANS Aka AFFERENT, conduct impulses TO brain and spinal cord (CNS)
Motor neurons - ANS Aka EFFERENT, conduct impulses FROM brain and spinal cord (CNS)
Interneurons - ANS Aka CENTRAL/ASSOCIATION, conduct impulses WITHIN the brain and
spinal cord, from place to place
Nerve - ANS Bundle of neuron fibers in the PNS
Tract - ANS Bundle of neuron fibers in the CNS
Action potentials - ANS Sudden nerve impulses/electrical changes that pass from one end of
the neuron to the other along the cell membrane
