Biology - Neural Control and Coordination Question with Solution | TestHub
When the transmission of nerve impulse across the synapse halts temporarily due to exhaustion of its neurotransmitter, it is termed as ________.
Options:
Answer:
Solution:
Synaptic fatigue is the temporary inability of neurons to fire and therefore transmit an input signal. It occurs when the presynaptic neuron is stimulated at high frequencies, leading to the depletion of neurotransmitter vesicles. This exhaustion of neurotransmitters temporarily halts the transmission of the nerve impulse across the synapse.
Synaptic delay refers to the time required for the neurotransmitter to be released, diffuse across the synaptic cleft, and bind to the receptors.
Refractory period is the brief period after an action potential during which a neuron cannot fire another action potential.
Summation effect is the additive effect of several electrical impulses on a neuromuscular junction.
Answer: Synaptic fatigue
