Neurons and Neural Transmission
Psychology ⇒ Biological Bases of Behavior
Neurons and Neural Transmission starts at 10 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Neurons and Neural Transmission.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 12
A student is studying the effects of a drug that blocks the reuptake of dopamine in the brain. What effect is this drug likely to have on dopamine levels in the synaptic cleft?
Describe the all-or-none principle in neural transmission.
Describe the difference between excitatory and inhibitory postsynaptic potentials (EPSPs and IPSPs).
Describe the process of synaptic transmission in your own words.
Explain how neurotransmitters are removed from the synaptic cleft after transmission.
Explain the role of the sodium-potassium pump in maintaining the resting potential of a neuron.
Explain why action potentials do not decrease in strength as they travel along the axon.
Name the process by which a neuron returns to its resting potential after an action potential.
What is the function of the myelin sheath in neural transmission?
What is the main difference between electrical and chemical synapses?
What is the main function of the axon terminal?
What is the refractory period in neural transmission?
What is the role of calcium ions (Ca²⁺) in synaptic transmission?
