neurons or synapses that produce and release glutamate

neurons or synapses that produce and release gamma-aminobutyric acid

neurons or synapses that produce and release peptide neurotransmitters

an anatomical method that uses antibodies to study the location of molecules within cells

a method for localizing strands of messenger RNA within cells

method for visualizing sites of radioactive emissions in tisssue sections

method of applying drugs and neurotransmitters in very small quantities to cells

one of several receptors to which a neutro transmitter binds

a class of acetylcholine-gated ion channel found in various locations (mainly at the neuromuscular junction)

a subtype of acetylcholine receptor that is a G-protein-coupled

a subtype of glutamate receptor; a glutamate-gated ion channel that is permeable to Na+ and k+

a subtype of glutamate receptor; a glutamate-gated ion channel that is permeable to Na+, K+, and Ca+. Inward ionic current through the N-methyl-d-aspartate receptor is voltage dependent bc of a magnesium block at neg. membrane potentials.

a subtype of of glutamate receptor; a glutamate gated-ion channel that is permeable to Na+ and K+

method that uses radioactive receptor ligands (agonists or antagonists) to locate neurotransmitter receptors

idea that a neuron has a unique identity with respect to neurontransmitter

one of two or more different neurotransmitters that are released from a single presynaptic nerve terminal

an amine that serves as a neurotransmitter at many synapses in the peripheral and central nervous systems, including the neuromuscular junction

a membrane protein that transports neurotransmitters, or their precursors, across membranes to concentrate them in either presynaptic cytosol or synaptic vessels

in the series of biochemical reactions that leads to the production of a chemical, the one step that limits the rate of synthesis

neurotransmitters dopamine, norepinephrine, and epinephrine

a catecholamine neurotransmitter synthesized from dopa

catecholamine neurotransmitter synthesized from dopamine; aka noradrenaline

a catecholamine neurotransmitter synthesized from norepinephrine; aka adrenaline

chemical precursor of dopamine and the other catecholamines

an amine neurotransmitter, 5 hydroxytryptamine

desrcrining neurons or synapses that produce and release serotonin

an amino acid; the major excitory neurotransmitter in the CNS

an amino acid; an inhibitory neurotransmitter at some locations in the CNS

amino acid synthesized from glutamate; the major inhibitory neurotransmitter in the CNS

a natural (endogenous) chemical that binds to, and activates, cannabinoid (CB) receptors

any chemical messenger that communicates info from the postsynaptic side foa synapse to the presynaptic side

a gas produced from the amino acid arginine that serves as an intercellular messenger

a class of drugs with antianxiety, sedative, muscle-relaxing, and anticonvulsant effects; acts by binding to GABA_A receptors and prolonging their inhibitory actions

a class of drugs with sedative , general anesthetic , and anticonvulsant effects; barbituates act in part by binding to GABA_A receptors and proloning their inhibitory

a multistep process that couples activation of a neurotransmitter receptor to activation of intracellular enzymes

a protein kinase activated by the second messeger cAMP

an enzyme that cleaves the membrane phospholipid phospatidylinositol-4-5-biphosphate to form the second messengers diacylglycerol (DAG) and inositol triphosphate (IP₃)

second messenger molecule formed by the action of phospholipase C on the membrane phospholipid phosphatidylinositol-4-5-biphosphate. it activates the enzyme protein kinase C

second messenger molecule formed by the action of phospholipase C on the membrane phospholipid phosphatidylinositol-4-5-bisphosphate. IP₃ causes the release of Ca²⁺ from intracellular stores

a protein kinase activated by the second messenger DAG

a protein kinase activated by the elevations of internal Ca²⁺ concentration

an enzyme that removes phosphate groups from proteins
