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 12
A patient is unable to form new memories after a brain injury. Which part of the brain is most likely damaged?
Describe the main difference between the central nervous system (CNS) and the peripheral nervous system (PNS).
Describe the main function of the spinal cord in the nervous system.
Describe the process of synaptic transmission.
Describe the role of neurotransmitters in the nervous system.
Explain how a nerve impulse is generated and propagated along a neuron.
Explain the difference between white matter and gray matter in the nervous system.
Explain the role of interneurons in the nervous system.
Explain why damage to the spinal cord can result in paralysis.
Name the two main divisions of the autonomic nervous system.
Which lobe of the human brain is primarily responsible for processing visual information?
Which neurotransmitter is primarily involved in muscle contraction at the neuromuscular junction?
Which of the following best describes the function of myelin in the nervous system?
Which part of the brain regulates homeostasis, including temperature and hunger?
A researcher records the following changes in membrane potential of a neuron: rapid depolarization, followed by repolarization and a brief hyperpolarization. What is the physiological basis for the hyperpolarization phase?
A toxin blocks the reuptake of neurotransmitters at the synaptic cleft. Predict and explain the effect this would have on synaptic transmission.
Describe the process of neural plasticity and its significance in learning and memory.
Explain how the blood-brain barrier protects the central nervous system and discuss one way in which it can be disrupted.
Explain the role of voltage-gated ion channels in the generation and propagation of action potentials.
