The _____ system is a network of cells that carries information to and from all parts of the body
Explanation
The nervous system is a complex network of cells, including neurons and glial cells, that transmits signals and carries information to and from all parts of the body. It is responsible for coordinating and controlling bodily functions, including sensory perception, motor responses, and cognitive processes. The nervous system consists of the central nervous system (brain and spinal cord) and the peripheral nervous system (nerves branching out from the spinal cord). It plays a crucial role in maintaining homeostasis and allowing organisms to interact with their environment.Rate this question:

The firing of a neuron is an all-or-nothing event that fires if the action potential is reached, but has no change if the action potential is not reached.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The firing of a neuron refers to the generation and transmission of an electrical signal called an action potential. This statement correctly states that the firing of a neuron is an all-or-nothing event. This means that once the action potential threshold is reached, the neuron will fire and transmit the signal along its axon. However, if the action potential threshold is not reached, the neuron will not fire and there will be no transmission of the signal. Therefore, the statement is true.Rate this question:

What part of the nervous system is involved in voluntary, skeletal muscle movement?
- A.
Parasympathetic system
- B.
Sympathetic system
- C.
Spinal cord
- D.
Somatic system
Correct Answer
D. Somatic systemExplanation
The somatic system is involved in voluntary, skeletal muscle movement. This system is responsible for transmitting signals from the brain to the skeletal muscles, allowing us to consciously control our movements. Unlike the autonomic nervous system, which controls involuntary functions, the somatic system is under our conscious control. Therefore, it is the correct answer to the question.Rate this question:

What is the methods for studying the brain that is used for mapping function that involves injection of a radioactive tracer?
- A.
MRI (magnetic resonance imaging) scan
- B.
CT (computed tomography) scan
- C.
PET (positron emission tomography) scan
- D.
EEG (electroencephalogram) scan
Correct Answer
C. PET (positron emission tomography) scanExplanation
PET (positron emission tomography) scan is the method used for studying the brain that involves injection of a radioactive tracer. This technique allows the visualization of brain activity by measuring the distribution of a radioactive substance that is injected into the bloodstream. The tracer emits positrons, which collide with electrons in the brain tissue, producing gamma rays that can be detected by the PET scanner. This information is then used to create a detailed map of brain function and activity. MRI and CT scans are imaging techniques that provide structural information, while EEG measures electrical activity in the brain.Rate this question:

Which brain structure allows us to pay attention to certain stimuli while ignoring others?
- A.
Medulla
- B.
Cerebellum
- C.
Reticular formation
- D.
Pons
Correct Answer
C. Reticular formationExplanation
The reticular formation is a brain structure that plays a crucial role in regulating arousal and attention. It filters incoming sensory information and determines which stimuli to focus on and which ones to ignore. This allows us to pay attention to certain stimuli while disregarding others. The medulla, cerebellum, and pons are not directly involved in attention and do not have the same functions as the reticular formation in this context.Rate this question:

The right hemisphere of the brain is involved more in written and spoken language and logical thought processes.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The right hemisphere of the brain is more involved in the nonverbal, creative, emotional thought and recognition, and facial and pattern recognition. The left hemisphere controls aspects of the spoken and written language, logical thought, and analysis of detail.Rate this question:

What part of the neuron receives messages from other cells?
- A.
Axon
- B.
Cell body
- C.
Axon Terminals
- D.
Dendrites
Correct Answer
D. DendritesExplanation
Dendrites are the part of the neuron that receive messages from other cells. They are branch-like structures that extend from the cell body and have many receptors on their surface. These receptors allow dendrites to receive chemical signals, called neurotransmitters, from other neurons. Once the neurotransmitters bind to the receptors on the dendrites, they generate electrical signals that are then transmitted to the cell body and further along the neuron through the axon. Therefore, dendrites play a crucial role in the communication between neurons by receiving and integrating incoming signals.Rate this question:

______ insulates and protects the axons of neurons that travel in the body and speeds up the neural message.
Correct Answer
MyelinExplanation
Myelin is a substance that insulates and protects the axons of neurons, which are responsible for transmitting neural messages throughout the body. By forming a sheath around the axons, myelin helps to speed up the transmission of these messages, allowing for more efficient communication between different parts of the nervous system.Rate this question:

Neurotransmitter molecules work by fitting into _______ sites on the next cell, stimulating or inhibiting that cell's firing.
Correct Answer
receptorExplanation
Neurotransmitter molecules work by fitting into receptor sites on the next cell, stimulating or inhibiting that cell's firing. Receptors are specialized proteins located on the surface of cells that specifically bind to neurotransmitters. When a neurotransmitter binds to its corresponding receptor, it triggers a series of chemical reactions that either excite or inhibit the receiving cell, influencing its firing or activity. This interaction between neurotransmitters and receptors is crucial for the transmission of signals in the nervous system.Rate this question:

What is the neurotransmitter associated with Parkinson's disease and schizophrenia?
- A.
Serotonin
- B.
Dopamine
- C.
Endorphins
- D.
Norepinephrine
Correct Answer
B. DopamineExplanation
Dopamine is the neurotransmitter associated with both Parkinson's disease and schizophrenia. In Parkinson's disease, there is a deficiency of dopamine in the brain, leading to movement difficulties and tremors. In schizophrenia, there is an imbalance of dopamine levels, with an excess of dopamine activity in certain areas of the brain, contributing to the symptoms of psychosis. Dopamine plays a crucial role in regulating movement, motivation, reward, and cognitive function, making it a key neurotransmitter involved in these two conditions.Rate this question:

Heroin mimics the actions of endorphins, inhibiting pain signals and creating a "high" feeling and thus is an _____ for heroin.
Correct Answer
agonistExplanation
Heroin mimics the actions of endorphins, which are natural pain-relieving chemicals in the body. By inhibiting pain signals and creating a "high" feeling, heroin acts as an agonist for itself. An agonist is a substance that activates or enhances the activity of a receptor in the body, in this case, the opioid receptors. Therefore, heroin acts as an agonist for the opioid receptors, producing its characteristic effects.Rate this question:

What is the specialization of function in each hemisphere, mainly regarding differences in language ability?
- A.
Corpus callosum
- B.
Laterilization
- C.
Somatic Nervous System
- D.
Central Nervous system
Correct Answer
B. LaterilizationExplanation
Laterilization refers to the specialization of function in each hemisphere of the brain, particularly regarding differences in language ability. It means that certain cognitive functions, such as language processing, are predominantly localized in one hemisphere of the brain, usually the left hemisphere in right-handed individuals. This specialization allows for efficient and coordinated processing of information.Rate this question:
