ACTUAL ASSESSMENT SCRIPT PAPER
QUESTIONS SOLUTIONS VERIFIED COMPLETE
GRADED A PLUS
◉ Motor neuron.
Answer: A neuron located within the central nervous system that
controls the contraction of a muscle or the secretion of a gland
◉ Interneuron.
Answer: A neuron located entirely within the central nervous system
◉ Central nervous system (CNS).
Answer: The brain and the spinal cord
◉ Peripheral nervous system (PNS).
Answer: The part of the nervous system outside the brain and spinal
cord, including the nerves attached to the brain and spinal cord
◉ Soma.
Answer: The cell body of a neuron, which contains the nucleus
,◉ Dendrite.
Answer: A branched, treelike structure attached to the soma of a
neuron; receives information from the terminal buttons of other
neurons
◉ Synapse.
Answer: A junction between the terminal button of an axon and the
membrane of another neuron
◉ Axon.
Answer: The long, thin, cylindrical structure that conveys
information from the soma of a neuron to its terminal buttons
◉ Multipolar neuron.
Answer: A neuron with one axon and many dendrites attached to its
soma
◉ Bipolar neuron.
Answer: A neuron with one axon and one dendrite attached to its
soma; primarily found in sensory systems (vision, audition, etc)
◉ Unipolar neuron.
, Answer: A neuron with one axon attached to its soma; the axon
divides, with one branch receiving sensory information and the
other sending the information into the central nervous system;
primarily found in the somatosensory system (touch, pain, etc)
◉ Terminal button.
Answer: The bud at the end of a branch of an axon; forms synapses
with another neuron; sends information to that neuron
◉ Neurotransmitter.
Answer: A chemical that is released by a terminal button; has an
excitatory or inhibitory effect on another neuron
◉ Membrane.
Answer: A structure consisting principally of lipid molecules that
defines the outer boundaries of a cell and also constitutes many of
the cell organelles, such as the Golgi apparatus
◉ Nucleus.
Answer: A structure in the central region of a cell, containing the
nucleolus and chromosomes
◉ Nucleolus.
