Questions to Ask About Neurological System Questions
Question 1 of 5
Communication within neurons is ______, communication between neurons is ________.
Correct Answer: D
Rationale: Communication within neurons is electrical, involving the propagation of action potentials along the axon. Communication between neurons, however, is chemical, relying on the release of neurotransmitters at the synapse. This combination of electrical and chemical signaling allows for rapid and precise communication within the nervous system, enabling complex behaviors and cognitive processes.
Question 2 of 5
When the individual is be unable to recognise everyday objects and name them correctly, this is known as
Correct Answer: C
Rationale: Agnosia is a neurological condition characterized by the inability to recognize or identify objects, people, sounds, or shapes, despite having intact sensory abilities. This condition arises from damage to specific areas of the brain responsible for processing sensory information. Agnosia can manifest in various forms, such as visual agnosia (inability to recognize objects) or auditory agnosia (inability to recognize sounds).
Question 3 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 4 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 5 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.
