PSY 101 Chapter 3 Biological Aspects of
Psychology
Biological Psychology - correct answer Psychological specialty focused on the
physical and chemical changes that cause, and occur in response to, behavior and mental processes
Nervous System - correct answer Complex combination of cells whose primary
function is to allow an organism to gain information about what is going on inside and outside the body
and to respond appropriately.
Neurons - correct answer Fundamental units of the nervous system, nerve cells.
Glial cells - correct answer Cells in the nervous system that hold neurons together
and help them communicate with one another.
Axons - correct answer Fibers that carry signals from the body of a neuron out to
communication with other neurons
Dendrites - correct answer Neuron fibers that receive signals from the axons of
other neurons and carry those signals to the cell body
Synapses - correct answer Tiny gaps between neurons across which they
communicate
Action potentials - correct answer Abrupt waves of electrochemical changes
traveling down an axon when a neuron becomes depolarized.
Myeline - correct answer Fatty substance that wraps around some axons and
increases the speed of action potentials.
, A refractory period - correct answer Short rest period between action potentials
Neurotransmitters - correct answer Chemicals that assist in the transfer of signals
from one neuron to another.
Receptors (Neural receptors) - correct answer Sites on the surface of a cell that
allow on type of neurotransmitter to fit into them, triggering a chemical response that may lead to an
action potential
Postsynaptic potential - correct answer Change in the membrane potential of a
neuron that has received stimulation from another neuron
Excitatory postsynaptic potential (EPSP) - correct answer Postsynaptic potential that
depolarizes the neuronal membrane, making the cell more likely to fire an action potential.
Inhibitory postsynaptic potential (IPSP) - correct answer Postsynaptic potential that
hyper polarizes the neuronal membrane, making a cell less likely to fire an action potential
Neural networks - correct answer Neurons that operate together to perform
complex functions
Peripheral nervous system - correct answer Major division of nervous system that is
not housed in bone
Central nervous system (CNS) - correct answer Major division go the nervous
system encased in bone; specifically, the brain and the spinal cord.
Somatic Nervous system - correct answer Subsystem of the peripheral nervous
system that transmits information from the senses to the CNS and carries signals from the CNS to the
muscles.
Sensory neurons - correct answer Cells in the nervous system that provide
information to the brain about the environment
