Exam 11: The Nervous System: Autonomic and Motor Systems

Which of the following descriptions of collateral ganglia is TRUE?

The nature of a response from the parasympathetic nervous system is determined by the anatomy of this system. Describe the anatomy of the parasympathetic nervous system and how that differs from the sympathetic nervous system.

Which of the following contributes to the ability of the sympathetic nervous system to produce widespread responses within the body?

What are swellings of postganglionic autonomic axons from which neurotransmitters are released called?

The autonomic nervous system innervates all the following effector organs and tissues EXCEPT

Acetylcholine is one of the most common neurotransmitters in the peripheral nervous system. Identify the branches of the peripheral nervous system for which acetylcholine is the neurotransmitter and describe the receptors responsible for responding to acetylcholine. Include the mechanisms whereby these receptors transduce the response to acetylcholine.

The parasympathetic nervous system exerts more discrete effects on effector organs than the sympathetic nervous system due to the independence of parasympathetic ganglia.

Students who suffer from test anxiety often have some of the following symptoms: the need for frequent urination, dilated pupils, and a dry mouth. What branch of the autonomic nervous system would cause these symptoms?

What area of the brain initiates the fight- or- flight response by producing widespread activation of the sympathetic nervous system?

Physiological stressors will cause parasympathetic nervous system activity to increase.

The somatic nervous system is often referred to as the system.

Compared to norepinephrine, epinephrine has a greater affinity for what type of receptor?

The preganglionic neurons of the sympathetic nervous system originate in the spinal cord from a region of gray matter called the intermediolateral cell column.

Which of the following is indicative of the relative release of catecholamines from the adrenal medulla?

What is the graded change in membrane potential that occurs at the motor end plate of skeletal muscle called?

The presence of within varicosities initiates the release of neurotransmitter.

Dual innervation of organs by the autonomic nervous system refers to the observation that

The primary hormone released from the adrenal medulla is norepinephrine.

Parasympathetic postganglionic neurons release the neurotransmitter ; sympathetic postganglionic neurons release the neurotransmitter .

Parasympathetic preganglionic neurons release the neurotransmitter ; sympathetic preganglionic neurons release the neurotransmitter _ .
