Exam 10: Autonomic and Somatic Nervous Systems

After a large meal the autonomic nervous system is very active. Describe the correct neural pathway and correctly identify which neurotransmitter is released at the effector(s).

Which of the following would NOT occur due to stimulation of the parasympathetic nervous system?

Which of the following is NOT an example of the somatic nervous system's contribution to homeostasis?

The dendrites of a preganglionic neuron of the autonomic motor pathway are found in the central nervous system.

At which location would you expect to find adrenergic receptors?

Using your understanding of the structure of the autonomic nervous system, select the most reasonable explanation for the differences in length of the postganglionic neurons of the parasympathetic and sympathetic nervous systems.

Which of the following is NOT an effector of the autonomic nervous system?

Which of the following correctly describes some of the physical characteristics of the sympathetic neurons?

Increased autonomic activity to the heart could have what effect on the activity of the heart?

Most sweat glands are not dually innervated by the two branches of the autonomic nervous system.

Which neurotransmitter is primarily secreted by axon endings of sympathetic postganglionic neurons?

The autonomic nervous system is typically under conscious control.

In order to slow an increased heart rate, which of the following is most likely to occur?

Which of the following is NOT an example of homeostatic regulation of sexual reproduction by the nervous system?

The end-plate potential is a type of graded potential.

Increased somatic nervous system activity could have what effect on the activity of skeletal muscles?

Monoamine oxidase (MAO) inhibitors are used to treat certain types of depression. What type of change in autonomic symptoms might a person taking MAO inhibitors experience?

At the neuromuscular junction, a somatic motor neuron's axon branches to innervate multiple muscle fibers in a muscle.

All postganglionic neurons of the autonomic nervous system release which neurotransmitter.

Botulinum toxin (Botox) injections are a popular cosmetic treatment because they allow an individual to temporarily reduce visible wrinkles in the skin (usually around the face). What is a probable mechanism of Botox at the neuromuscular junction?
