Nervous System starts at 7 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Nervous System.
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

Describe the main difference between the somatic and autonomic nervous systems.
Describe the process of repolarization during an action potential.

Describe the sequence of events that occur during synaptic transmission.
Explain how neurotransmitters are removed from the synaptic cleft after transmission.

The _______ is a bundle of nerve fibers that connects the left and right hemispheres of the brain.
The _______ is the outermost layer of the meninges.
The _______ is the part of the brain responsible for maintaining balance and coordinating voluntary movements.

True or False: All neurons are capable of regeneration after injury.
True or False: Motor neurons carry impulses from the central nervous system to effectors such as muscles or glands.
True or False: The autonomic nervous system controls both smooth muscle and cardiac muscle.
True or False: The blood-brain barrier allows all substances in the blood to enter the brain tissue.
