Biological Bases of Behavior
What is the primary role of the Central Nervous System (CNS)?
A. Relaying signals between the body and brain
B. Regulating involuntary processes like heart rate
C. Processing sensory information and sending motor commands
D. Controlling voluntary movements of skeletal muscles
Which of the following is a component of the Peripheral Nervous System (PNS)?
A. Spinal Cord
B. Brain
C. Nerves
D. Cerebellum
What is the main function of the Peripheral Nervous System (PNS)?
A. To process sensory information and make decisions
B. To regulate involuntary functions like digestion
C. To serve as a communication relay between the CNS and the rest of the body
D. To control voluntary movements of skeletal muscles
In a stressful situation, such as encountering a bear in the woods, which division of the autonomic nervous system would be most active?
A. The somatic nervous system
B. The parasympathetic nervous system
C. The sympathetic nervous system
D. The central nervous system
How does the Somatic Nervous System (SNS) enable interaction with the external environment?
A. By directly regulating blood pressure and body temperature
B. By controlling the release of adrenaline during stress
C. By allowing us to move our skeletal muscles and experience sensations like touch and pain
D. By automatically adjusting our breathing rate during exercise
How do the Somatic and Autonomic Nervous Systems (SNS and ANS) coordinate to carry out complex behaviors?
A. The SNS controls only voluntary movements, while the ANS controls only involuntary processes, without any interaction.
B. The SNS and ANS work together, with the SNS initiating voluntary actions and the ANS adjusting internal functions to support those actions.
C. The SNS and ANS operate independently, with the SNS responding to external stimuli and the ANS responding to internal stimuli.
D. The SNS and ANS compete with each other, with one system dominating depending on the situation.
Which of the following is a primary component of the Central Nervous System (CNS)?
A. Nerves
B. Brain
C. Ganglia
D. Sensory Receptors

What is the primary function of the Somatic Nervous System (SNS)?
A. Regulating heart rate and digestion
B. Controlling voluntary movements and behaviors

Which function exemplifies the integrative role of the Central Nervous System (CNS)?
A. Reflex actions controlled by the spinal cord
B. Regulation of heart rate during sleep
C. The experience of feeling an emotion like happiness
D. Transmission of pain signals from the skin to the brain
