Which division of the autonomic nervous system is responsible for the 'fight or flight' response?
Sympathetic nervous system
Which division of the autonomic nervous system is primarily concerned with conservation of energy and maintenance of organ function during periods of minimal activity?
Parasympathetic nervous system
Which type of autonomic fibers are responsible for the 'rest and digest' response?
Parasympathetic fibers
Which type of autonomic fibers are responsible for the 'fight or flight' response?

Which division of the autonomic nervous system is responsible for controlling the processes of mixing, propulsion, and absorption of nutrients in the gastrointestinal tract?
Enteric nervous system
Which neurotransmitter is released by all preganglionic neurons of the ANS?
Acetylcholine
Which type of receptors are activated by acetylcholine or nicotine and produce excitation?
Neuronal nicotinic receptors
Which type of receptors are activated by G-proteins and mediate slow EPSP in autonomic ganglia?
M1 muscarinic receptors
Which G-protein coupled receptor subtype controls the release of neurotransmitter by other neurons and is inhibitory in the sympathetic nervous system?

Which division of the Autonomic Nervous System is responsible for the "inhibition of random movement" and "awareness of sensations"?
Parasympathetic division
Which component of the Central Nervous System is responsible for "sensory perception", "voluntary movement", and "memory/decision making"?
Cerebral cortex
Which component of the Central Nervous System is responsible for "balance", "muscle tone", and "coordination of voluntary muscle act"?
Cerebellum
Which component of the Central Nervous System serves as the "relay station for all synaptic input" and is responsible for "inhibition of random movement"?
Thalamus
Which component of the Central Nervous System is responsible for the "homeostatic regulation of temperature, thirst, food intake, fluid balance, and biological rhythms"?
Hypothalamus
Which division of the Peripheral Nervous System is divided into autonomic/enteric and somatic?
Sympathetic division
Test your knowledge of the sympathetic nervous system and its role in the "fight or flight" response. Explore its effects on various organs and functions, including heart rate, blood vessels, bronchi, digestion, and more. See if you can identify the correct preganglionic fibers in this division of the spinal cord.
