Animal Nervous System starts at 9 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Animal 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 11
Describe the difference between the central nervous system and the peripheral nervous system.
Describe the main difference between a nerve and a ganglion.
Describe the process of synaptic transmission.
Describe the role of the blood-brain barrier.
Explain how a reflex arc works, using an example.
A student touches a hot object and immediately withdraws their hand. Which type of response is this?
(1) Voluntary
(2) Reflex
(3) Hormonal
(4) Learned
A patient is unable to feel pain or temperature in their left leg, but can still move it voluntarily. Which part of the nervous system is most likely damaged?
(1) Motor neurons in the left leg
(2) Sensory neurons in the left leg
(3) Autonomic nervous system
(4) Cerebellum
A researcher records the following sequence of events in a neuron: rapid influx of Na+, followed by efflux of K+, and then restoration of the resting potential. What process is being described?

The __________ is a bundle of axons in the peripheral nervous system.
The __________ is the insulating layer that surrounds some axons and increases the speed of nerve impulse transmission.
The __________ is the largest part of the human brain and is responsible for higher functions such as thought and action.
The __________ nervous system controls involuntary actions such as heartbeat and digestion.
True or False: Action potentials travel faster in unmyelinated axons than in myelinated axons.
True or False: All animals have a brain.
True or False: Invertebrates such as insects have a ventral nerve cord.
True or False: Myelin sheaths increase the speed of nerve impulse transmission.
