Exam 16: Autonomic Nervous System

The parasympathetic division is also called the thoracolumbar division.

The parasympathetic and sympathetic divisions always act with a cooperative influence,and through summation of the impulses,the effect can be increased.

Most effectors of the autonomic nervous system are dually innervated by sympathetic and parasympathetic neurons.

Which is not true about sympathetic postganglionic neurons?

Which of the following statements is not true?

The gray ramus consists of postganglionic fibers of the sympathetic nervous system.

Match each term with its description or definition. -structure through which preganglionic sympathetic neurons that did not synapse in the sympathetic chain ganglion continue

Alpha receptors are stimulated by acetylcholine,whereas beta receptors are stimulated by norepinephrine.

The sympathetic trunk runs from C8 to L4.

What brain structure acts as a "connection" between the cerebrum and the autonomic nervous system?

Contrast somatic motor pathways with autonomic pathways.

Conduction to autonomic effectors requires only one efferent neuron.

Match each term with its description or definition. -informal term used to describe the response of the body to sympathetic nervous system stimulation

Match each term with its description or definition. -informal term used to describe the response of the body to parasympathetic nervous system stimulation

The autonomic nervous system functions independently of the cerebral cortex.

Effectors that have single innervation by the autonomic nervous system are innervated only by the parasympathetic division.

Explain physiologically how summation influences effectors doubly innervated by the autonomic nervous system.

Acetylcholine can stimulate _____ receptors.

Somatic motor and autonomic pathways share all of the following characteristics except:

Norepinephrine can stimulate nicotinic or muscarinic receptors.
