Health Assessment Neurological System Questions Questions
Question 1 of 5
Nerve impulses create a change in voltage which is measured by and can be seen on a(n) ________.
Correct Answer: C
Rationale: An oscilloscope is a device used to measure and display changes in voltage over time, making it ideal for visualizing nerve impulses. When a nerve impulse occurs, it creates a rapid change in membrane potential, which can be recorded as a waveform on the oscilloscope. This tool is commonly used in neuroscience research to study the electrical activity of neurons and understand how nerve impulses are generated and propagated.
Question 2 of 5
Like other systems in the body, the nervous system is composed of organs, principally the brain, spinal cord, nerves, and _______.
Correct Answer: A
Rationale: The nervous system is composed of several key organs, including the brain, spinal cord, nerves, and ganglia. Ganglia are clusters of nerve cell bodies located outside the central nervous system and play a role in processing and transmitting nerve signals. Axons and neurons are components of nerves, while the dura mater is a protective membrane surrounding the brain and spinal cord. Ganglia are the correct answer as they are distinct organs within the nervous system.
Question 3 of 5
A neuron with a cell body located in the CNS whose primary function is connecting other neurons is called a(n):
Correct Answer: C
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 4 of 5
Lobe that contains the primary motor area that enables voluntary control of skeletal muscle movements:
Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 5 of 5
To test for stereognosis you would
Correct Answer: C
Rationale: Stereognosis is the ability to perceive and recognize the form of an object using touch. To test for stereognosis, place a familiar object, such as a coin, in the patient's hand and ask them to identify it with their eyes closed. This assesses the sensory cortex's ability to interpret tactile sensations.
