Questions to Ask About Neurological System Questions
Question 1 of 5
Which structure allows communication between the hemispheres?
Correct Answer: D
Rationale: The corpus callosum is a thick bundle of nerve fibers that connects the left and right hemispheres of the brain, allowing for communication and coordination between them. It enables the integration of information from both sides of the brain, facilitating complex cognitive processes and motor coordination. Damage to the corpus callosum can result in disconnection syndromes, where the hemispheres cannot communicate effectively.
Question 2 of 5
Executive functioning involves the integrated use of several cognitive processes by which people problem-solve, plan, initiate, organise and monitor goal-directed activities. Deficits in this collection of integrated skills involves which kind of training:
Correct Answer: A
Rationale: Goal Management Training (GMT) is a therapeutic approach designed to improve executive functioning by teaching individuals how to set, prioritize, and achieve goals. This training involves breaking down complex tasks into manageable steps, monitoring progress, and adjusting strategies as needed. GMT is particularly effective for individuals with neurological disorders or brain injuries that impair executive functions, helping them regain independence and improve daily functioning.
Question 3 of 5
An interneuron has _____________.
Correct Answer: D
Rationale: Interneurons, which are found within the CNS, typically have short dendrites and either a long or short axon. These neurons act as connectors between sensory and motor neurons, integrating and processing information to generate appropriate responses. The structure of interneurons allows them to facilitate communication within the CNS, enabling complex reflexes and higher-order cognitive functions.
Question 4 of 5
As the potassium ions move out of the axon, the oscilloscope records a ________.
Correct Answer: B
Rationale: As potassium ions move out of the axon during repolarization, the oscilloscope records a return of the membrane potential to its negative resting state. This phase of the action potential is called repolarization and is essential for resetting the neuron so it can fire another action potential. Repolarization ensures that the neuron is ready to transmit subsequent nerve impulses.
Question 5 of 5
The tiny space between neurons or a neuron and its target muscle is the:
Correct Answer: D
Rationale: The synapse is the tiny gap between neurons or between a neuron and its target cell, such as a muscle. It is the site where neurotransmitters are released to transmit signals from one cell to another. When an action potential reaches the axon terminal, neurotransmitters are released into the synapse and bind to receptors on the postsynaptic cell, triggering a response. The synapse is crucial for communication within the nervous system.
