psychology Crossword

the basic working unit of the brain
nerve cells that carry impulses towards the central nervous system
nerve cells that conduct impulses away from the central nervous system(causes muscle movement)
branch-like parts of a neuron that are specialized to receive information
a thread like extension of a neuron that carries nerve impulses away from the cell body
cell body
covers the axon of some neurons and helps speed neural impulse
gaps in the myelin sheath to which voltage-gated sodium channels are confined
the junction between the axon tip of the sending neuron and the dendrite or cell body of the receiving neuron
a gap into which neurotransmitters are released from the axon terminal
the difference in electric charge between the inside and outside of a neurons cell membrane
the process durning the action potential when sodium is rushing into the cell causing the interior to become more positive
a neural impulse, a brief electrical charge that travels down the axon
the period of time durning which a second action potential absolutely can not be initiated
changes in the membrane potential of the postsynaptic terminals
chemical messengers that cross the synaptic gaps between neurons
A neurotransmitter associated with movement, attention and learning and the brain's pleasure and reward system.
A neurotransmitter that affects hunger,sleep, arousal, and mood.
peptides that bind to opioid receptors in the brain
chemical in the brain that plays a specialized role in pain reduction
a major inhibitory neurotransmitter
Acetylcholine A neurotransmitter that enables learning and memory and also triggers muscle contraction
A neurotransmitter involved in arousal, as well as in learning and mood regulation
chemicals released in the nervous system that influence the sensitivity of the receiving neuron to neurotransmitters
A neurotransmitter that is involved in the transmission of pain messages to the brain.
a molecule that, by binding to a receptor site, stimulates a response
A chemical or drug that binds receptors in the brain and stops the agonist from having a reaction.
record of the electrical activity of the brain
