What are the two divisions of the Autonomic Nervous System?
-
Central and Peripheral
-
Sympathetic and Parasympathetic
-
Somatic and Sympathetic
-
Peripheral and Sympathetic
Correct Answer
A. Sympathetic and ParasympatheticExplanation
The Autonomic Nervous System is divided into two divisions: the Sympathetic and Parasympathetic divisions. The Sympathetic division is responsible for the body's "fight or flight" response, increasing heart rate, blood pressure, and adrenaline production. The Parasympathetic division, on the other hand, controls the body's "rest and digest" response, promoting relaxation, slowing heart rate, and stimulating digestion. These two divisions work in opposition to maintain a balance in the body's functions and responses to external stimuli.Rate this question:

Sympathetic activation causes a decrease in the heart rate.
-
True
-
False
Correct Answer
A. FalseExplanation
Sympathetic activation actually causes an increase in heart rate, not a decrease. The sympathetic nervous system is responsible for the "fight or flight" response, which prepares the body for action by increasing heart rate, blood pressure, and respiration rate. Therefore, the statement that sympathetic activation causes a decrease in heart rate is incorrect.Rate this question:

What are the two major divisions of the nervous system?
-
Peripheral and Autonomic
-
Somatic and Autonomic
-
Central and Peripheral
-
Sympathetic and Parasympathetic
Correct Answer
A. Central and PeripheralExplanation
The nervous system is divided into two major divisions: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS consists of the brain and spinal cord, which are responsible for processing and coordinating information. The PNS includes all the nerves that extend from the CNS to the rest of the body, allowing for communication between the CNS and the organs, muscles, and sensory receptors. This division allows for the efficient functioning of the nervous system by separating the control and processing centers from the communication and sensory pathways.Rate this question:

What is the Autonomic system sometimes called?
-
Involuntary nervous system
-
Voluntary movement system
-
Organic nervous system
-
Inorganic nervous system
Correct Answer
A. Involuntary nervous systemExplanation
The autonomic system is sometimes called the involuntary nervous system because it controls involuntary bodily functions such as heart rate, digestion, and breathing. These functions are not under conscious control and are regulated automatically by the autonomic system.Rate this question:

Activation of the Sympathetic Nervous System can cause which of these reactions?
-
Decrease in heart rate and vasoconstriction of peripheral blood vessels
-
Decrease in heart and vasodilation of peripheral blood vessels.
-
Increase in heart rate and vasoconstriction of peripheral blood vessels.
-
Increase in voluntary movement as part of the somatic nervous system.
Correct Answer
A. Increase in heart rate and vasoconstriction of peripheral blood vessels.Explanation
Activation of the Sympathetic Nervous System is responsible for the fight-or-flight response in the body. This response prepares the body for action in response to a perceived threat or stressor. One of the primary effects of sympathetic activation is an increase in heart rate, which helps to pump more oxygenated blood to the muscles and organs. Additionally, sympathetic activation causes vasoconstriction of peripheral blood vessels, which redirects blood flow away from non-essential organs towards the muscles and other vital organs. This combination of increased heart rate and vasoconstriction helps to increase blood flow and oxygen delivery to the areas of the body that need it most during a stress response.Rate this question:

Which part of the Nervous System is responsible for the Fight or Flight reaction?
-
Parasympathetic
-
Sympathetic
-
Somatic
-
Cholinergic
Correct Answer
A. SympatheticExplanation
The sympathetic nervous system is responsible for the fight or flight reaction. When faced with a perceived threat, this part of the nervous system activates and prepares the body for action. It increases heart rate, dilates blood vessels, and releases stress hormones like adrenaline, allowing the individual to either fight the threat or flee from it. The parasympathetic nervous system, on the other hand, is responsible for rest and digest activities, promoting relaxation and conserving energy. The somatic nervous system controls voluntary movements, while cholinergic refers to the type of neurotransmitter involved in nerve signaling.Rate this question:

Sympathetic Activation causes vasoconstriction of the blood vessels in the periphery.
-
True
-
False
Correct Answer
A. TrueExplanation
Sympathetic activation refers to the activation of the sympathetic nervous system, which is responsible for the "fight or flight" response. When this system is activated, it causes vasoconstriction, which is the narrowing of blood vessels. This narrowing of blood vessels in the periphery helps to redirect blood flow to vital organs and muscles, preparing the body for physical exertion or a stressful situation. Therefore, the statement that sympathetic activation causes vasoconstriction of the blood vessels in the periphery is true.Rate this question:

The peripheral nervous system itself is made up of which two subdivisions?
-
Somatic and autonomic nervous system
-
Sympathetic and parasympathetic nervous system
-
Somatic and voluntary nervous system
-
Cholinergic and adrenergic nervous systems
Correct Answer
A. Somatic and autonomic nervous systemExplanation
The correct answer is somatic and autonomic nervous system. The peripheral nervous system is divided into two main subdivisions: the somatic nervous system and the autonomic nervous system. The somatic nervous system controls voluntary movements and transmits sensory information to the central nervous system. The autonomic nervous system regulates involuntary bodily functions, such as heart rate, digestion, and breathing.Rate this question:
-
- 10.
The parasympathetic nervous system has the primary regulation of peripheral blood vessel constriction.
-
True
-
False
Correct Answer
A. FalseExplanation
The parasympathetic nervous system is responsible for the relaxation and dilation of blood vessels, not constriction. This allows for increased blood flow and decreased blood pressure.Rate this question:
