ATI Neurological System Questions Questions
Question 1 of 5
Which of the following is NOT a lobe of the brain?
Correct Answer: B
Rationale: The brain is divided into four main lobes: frontal, parietal, temporal, and occipital. The dorsal aspect refers to the upper part of the brain or spinal cord and is not a specific lobe. Each lobe has distinct functions, such as the frontal lobe's role in decision-making and the temporal lobe's involvement in hearing and language. The dorsal term is used anatomically to describe location rather than structure.
Question 2 of 5
A Neurological disorder that is characterised by impairments in motor performance and coordination are known as
Correct Answer: B
Rationale: Apraxia is a neurological disorder that affects the ability to perform purposeful movements, despite having the physical ability and desire to do so. Individuals with apraxia may struggle with tasks like dressing, cooking, or using tools. This condition is often caused by damage to the parietal lobe or other areas of the brain involved in motor planning and execution.
Question 3 of 5
A technique that has proven to be helpful in training individuals with amnesia, where people are prevented - as far as possible - from making any errors while learning a new skill or new information is known as:
Correct Answer: B
Rationale: Errorless learning is a training technique used to help individuals with amnesia acquire new skills or information without making mistakes. By minimizing errors during the learning process, this method enhances memory retention and reduces the likelihood of incorrect information being stored. Errorless learning is particularly effective for individuals with memory impairments, as it leverages their residual learning abilities and promotes successful skill acquisition.
Question 4 of 5
Schwann cells are one of several types of ________ cells in the nervous system.
Correct Answer: D
Rationale: Schwann cells are a type of neuroglial cell found in the peripheral nervous system (PNS). They are responsible for producing myelin, which insulates axons and enhances the speed of nerve impulse transmission. Other types of neuroglial cells include astrocytes, oligodendrocytes, and microglia, each of which supports and protects neurons in different ways. Schwann cells are essential for maintaining the health and function of peripheral neurons.
Question 5 of 5
A refractory period is___________.
Correct Answer: A
Rationale: The refractory period is a brief time following an action potential during which a neuron is unable to fire another impulse. This period ensures that action potentials propagate in one direction and allows the neuron to reset its ion gradients. The refractory period is divided into the absolute refractory period, when no new action potentials can be generated, and the relative refractory period, when a stronger-than-usual stimulus is required to generate an action potential.
