Health Assessment Neurological System Questions Questions
Question 1 of 5
The poison curare is a(n) ________ for the neurotransmitter acetylcholine.
Correct Answer: A
Rationale: Curare is an antagonist for the neurotransmitter acetylcholine, meaning it blocks acetylcholine receptors at the neuromuscular junction. This prevents acetylcholine from binding to its receptors and initiating muscle contraction, leading to paralysis. Curare has been used historically as a poison and in medical procedures to induce muscle relaxation. Its action highlights the importance of acetylcholine in muscle function and the effects of receptor blockade.
Question 2 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 3 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 4 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 5 of 5
Acetylcholine and norepinephrine are two well-known _________.
Correct Answer: D
Rationale: Acetylcholine and norepinephrine are two well-known neurotransmitters that play critical roles in the nervous system. Acetylcholine is involved in muscle contraction, memory, and learning, while norepinephrine regulates attention, arousal, and stress responses. These neurotransmitters bind to specific receptors on postsynaptic neurons, triggering electrical signals that propagate neural communication. Their proper functioning is essential for normal brain and body activities.
