問題一覧

class of neurotransmitter that are enzymatically derived from amino acid but no longer contain carboxyl group

biogenic amines

connection between two neurons or between a neuron and its target where the neurotransmitter diffuses across a very short distance

chemical synapse

neurotransmitter system of acetylcholine which includes its receptor and the enzyme acetylcholinesterase

cholinergic system

enzyme that catalyzes the generation of a new molecule which acts as the intracellular mediators of the signal that binds to the receptor

effector protein

connection between two neurons or any two electrically active cells were ions flow directly through channels spanning there adjacent cell membrane

electrical synapse

guanosine triphosphate hydrolysis that physically move from the receptor protein to the effector protein to activate the latter

g protein

neurotransmitter receptor that involves a complex of protein that cause metabolic changes in a cell

metabotropic receptor

type of acetylcholine receptor protein that is factorize by also binding to muscarine and is metabotropic receptor

muscarinic receptor

neurotransmitter type that includes protein molecules and shorter chain of amino acid

neuropeptide

chemical signals that is released from the synaptic end bulb of a neuron to cause a change in the target cell

neurotransmitter

type of acetylcholine receptor protein that is characterized by also binding to nicotine and is an ionotropic receptor

nicotinic receptor

graded potential in the postsynaptic membrane caused by the binding of neurotransmitter to protein receptor

postsynaptic potential (PSP)

the difference in voltage measured across a cell membrane under steady state condition, typically -70 mV

resting membrane potential

narrow junction across which a chemical signal passes from neuron to the next, initiating a new electrical signals in the target cell

synapse

small gap between cells in a chemical synapse where neurotransmitter diffuses from the presynaptic elements to the postsynaptic elements

synaptic cleft

swelling at the end of an axon where neurotransmitter molecules are released onto a target cell across a synapse

synaptic end bulb

combination of graded potential at the same location on a Neuron resulting in a strong signal from one input

temporal summation

combined of graded potential across the neuronal cell membrane caused by signals from separate presynaptic elements and add up to initiate an action potential

spatial summation

return of the membrane potential to its normally negative voltage at the end of action potential

repolarization

property of an axon that relates to the ability of particles to diffuse through the cytoplasm; this is inversely proportional to the fiber diameter

resistance

combination of graded potential across the neuronal cell membrane caused by signals from separate presynaptic elements that add up to initiate an action potential

spatial summation

to add together, as in the cumulative change in postsynaptic potential towards reaching threshold in the membrane either cross a span of the membrane or over a certain amount of time

summate

graded potential in a specialized sensory cell that directly causes the release of neurotransmitter without an intervening action potential

receptor potential

graded potential in the postsynaptic membrane that is the result of hyperpolarization and makes an action potential less likely to occur

ipsp

graded potential in the postsynaptic membrane that is the result of depolarization and make an action potential more likely to occur
