Neurological System NCLEX Questions Questions
Question 1 of 5
When an individual has a disruption of the ability to speak is known generally as
Correct Answer: B
Rationale: Broca's aphasia is a language disorder that disrupts the ability to speak fluently. Individuals with this condition often experience difficulty in forming complete sentences, finding the right words, and articulating speech. This condition is caused by damage to Broca's area, located in the frontal lobe of the brain, which plays a critical role in speech production and language processing.
Question 2 of 5
Neuroglial cells support and provide nutrition for the ________.
Correct Answer: C
Rationale: Neuroglial cells, also known as glial cells, are non-neuronal cells that provide support and nutrition to neurons. They play essential roles in maintaining homeostasis, forming myelin sheaths, and protecting neurons from damage. Types of neuroglial cells include astrocytes, oligodendrocytes, microglia, and Schwann cells. These cells ensure the proper functioning of the nervous system by creating a supportive environment for neurons.
Question 3 of 5
A nerve fiber obeys an all-or-none law insofar as it either fires or does not fire depending on whether the stimulus is above a threshold.
Correct Answer: A
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 4 of 5
The Peripheral Nervous System is made up of the:
Correct Answer: B
Rationale: The peripheral nervous system (PNS) includes all the nerves outside the central nervous system, such as spinal nerves and cranial nerves. It connects the CNS to the limbs, organs, and skin, allowing for the transmission of sensory and motor signals. The PNS is divided into the somatic nervous system, which controls voluntary movements, and the autonomic nervous system, which regulates involuntary functions like heart rate and digestion.
Question 5 of 5
One of the three basic parts of a neuron is the ________.
Correct Answer: A
Rationale: A neuron consists of three basic parts: the cell body, dendrites, and axon. The axon is a long, slender projection that transmits nerve impulses away from the cell body to other neurons or target cells. Myelin is a protective sheath around some axons, the pons is a part of the brainstem, and the dura mater is a meningeal layer. Therefore, axon is the correct answer as it is one of the fundamental components of a neuron.
