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 11
A student is learning about neural transmission. She reads that when a neuron is stimulated, the inside of the cell becomes less negative. What is this process called?
Describe the all-or-none principle in neural transmission.
Describe the difference between afferent and efferent neurons.
Describe the role of calcium ions in neurotransmitter release at the synapse.
Explain how drugs that block reuptake of neurotransmitters can affect neural transmission.
Explain the role of the sodium-potassium pump in maintaining the resting potential of a neuron.
A patient is unable to move certain muscles after a nerve injury. Which type of neuron is most likely damaged? (1) Sensory neuron (2) Motor neuron (3) Interneuron (4) Glial cell

Fill in the blank: The _______ insulates axons and speeds up neural transmission.
Fill in the blank: The _______ is the long, slender projection of a neuron that conducts electrical impulses away from the cell body.
Fill in the blank: The _______ period is the brief time after an action potential during which a neuron cannot fire another action potential.
The gap between two neurons where neurotransmitters are released is called the _______.
True or False: Action potentials travel faster in myelinated axons than in unmyelinated axons.
True or False: All neurons have the same shape and size.
True or False: Neurotransmitters are only found in the brain.
True or False: Neurotransmitters can only have one effect on the postsynaptic neuron.
