Psychobiology Exam 1
action potential-✔✔a brief electrical charge that travels down an axon
Starts at the axon hilloks is all of nothing
Adenosine Triphosphate (ATP)-✔✔compound used by cells to store and
release energy
Anion-✔✔A negatively charged ion
anterograde transport-✔✔movement down the axon Away from soma
(new proteins) *A and A (away and anterograde)
Astrocyte-✔✔a glial cell that provides physical support, transports
nutrients, increases blood flow, helps form synapses
Autonomic Nervous System-✔✔A part of the peripheral nervous system
that provides the main neural connections to the internal organs. consist of
the Parasympathetic and Sympathetic nervous system
autoreceptors-✔✔signal the presynaptic neuron to stop releasing the
neurotransmitter
Axon-✔✔A single extension from the nerve cell that carries the electrical
signal from the cell body toward axon terminals. Is in the conduction zone
Axon Hillock-✔✔the cone-shaped area on the cell body from which the
axon originates
Axon Terminal-✔✔the end of an axon or axon collateral, which forms a
synapse on a neuron or other target cell
behavioral intervention-✔✔-manipulating the behavior may affect the body
and/or the brain -Independent variable: Behavior -Dependent variable:
body/brain changes
, brain-✔✔The mass of nerve tissue that is the main control center of the
nervous system
Calcium-✔✔-Ca2+ -equilibrium potential= +120 mV -is Cations
Cations-✔✔positively charged ions
cell body (soma)-✔✔-is part of the Integration Zone
Central Nervous System (CNS)-✔✔consists of the brain and spinal cord
c-fos-✔✔help visualize neuronal activity of cells
Chloride (Cl)-✔✔-equilibrium potential is -60 mV -is an Anions
Concentration gradient-✔✔Movement from areas of high to low
concentration
correlational studies-✔✔a research method that examines how variables
are naturally related in the real world, without any attempt by the
researcher to alter them or assign causation between them
Dendrite-✔✔an extension of the cell body that receives information from
other neurons part of the input zone
Diffusion-✔✔transmitter substance floats away from the synapse
Dualism-✔✔mind and body are separate
dual = two
Dynactin protein-✔✔transports back to soma in retrograde transport
electrostatic pressure-✔✔-Movement towards oppositely charged areas
-like charges repel and opposites attract
