Health Assessment Neurological System Questions Questions
Question 1 of 5
What part of a neuron is responsible for receiving information?
Correct Answer: C
Rationale: Dendrites are the part of a neuron responsible for receiving information from other neurons. They are branched structures that extend from the cell body and contain receptors for neurotransmitters. When neurotransmitters bind to these receptors, they generate electrical signals that travel toward the cell body, initiating communication between neurons. Dendrites play a crucial role in integrating incoming signals and determining whether the neuron will fire an action potential.
Question 2 of 5
The brain's ability to change in response to experience or damage is called:
Correct Answer: C
Rationale: Neuroplasticity refers to the brain's ability to reorganize itself by forming new neural connections in response to learning, experience, or injury. This adaptability allows the brain to compensate for damage and recover lost functions. Neuroplasticity is the basis for learning and memory and plays a crucial role in rehabilitation after brain injury. It highlights the brain's remarkable capacity for change and adaptation.
Question 3 of 5
In the United States of America one most common neuropsychological tests used is known as:
Correct Answer: B
Rationale: The Halstead-Reitan Neuropsychological Test Battery is one of the most commonly used neuropsychological assessments in the United States. It consists of a series of tests designed to evaluate brain and nervous system functioning, including measures of cognitive, motor, and sensory abilities. This battery is particularly useful for diagnosing brain damage, assessing the severity of neurological disorders, and planning rehabilitation strategies.
Question 4 of 5
In brain injury a severe trauma in which the brain is not just jarred but the impact also causes bruising to the brain is known as:
Correct Answer: B
Rationale: A contusion is a type of brain injury characterized by bruising and damage to brain tissue, often resulting from a direct impact to the head. Unlike a concussion, which involves temporary dysfunction without visible damage, a contusion causes physical injury to the brain, leading to swelling, bleeding, and potential long-term neurological deficits. Contusions require careful monitoring and treatment to prevent complications such as increased intracranial pressure.
Question 5 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.
