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 10
Describe the all-or-none principle in neural transmission.
Describe the role of the axon hillock in neural transmission.
Describe what happens at the synapse during neural transmission.
Explain the difference between excitatory and inhibitory neurotransmitters.
Explain the role of neurotransmitters in neural transmission.
Explain why the myelin sheath is important for neural transmission.

Fill in the blank: The __________ is a fatty substance that covers some axons and increases the speed of neural transmission.
Fill in the blank: The __________ is the junction between the axon terminal of one neuron and the dendrite of another.
Fill in the blank: The __________ is the part of the neuron that contains the nucleus and most of the cell’s organelles.
Fill in the blank: The __________ is the part of the neuron that transmits electrical impulses to other cells.
True or False: Action potentials travel faster in myelinated axons than in unmyelinated axons.
True or False: All neurons are identical in structure and function.
True or False: Dendrites transmit signals away from the neuron’s cell body.
True or False: Neurotransmitters are only found in the brain.
