Dual innervation of organs by both branches of the autonomic nervous system allows a fine degree of control over these organs.

The overall functioning of the ANS contributes to

Identify the true statement(s):

Indicate whether the following autonomic anatomical and physiological features pertain to a.the parasympathetic division b.the sympathetic division c.both parasympathetic and sympathetic divisions d.neither parasympathetic nor sympathetic divisions -Innervate most blood vessels and sweat glands

The neurotransmitter at a neuromuscular junction is

Acetylcholine

It is possible through the use of drugs to activate the receptors found in bronchiolar smooth muscle without influencing the receptors in the heart.

Indicate whether the following autonomic anatomical and physiological features pertain to a.the parasympathetic division b.the sympathetic division c.both parasympathetic and sympathetic divisions d.neither parasympathetic nor sympathetic divisions -Decreases exocrine activity of the pancreas

Any autonomic neuron that conducts impulses out of the CNS will transmit those impulses to a postganglionic neuron.

Compare and contrast the autonomic and somatic nervous systems with reference to the following: (1) the types of effectors stimulated; (2) number of neurons involved; and (3) the specific neurotransmitters released onto effectors.

Postganglionic autonomic fibers

Most sympathetic postganglionic fibers have cell bodies in a sympathetic ganglion ____________________, also called the sympathetic _________.

NE can cause inhibition of certain effectors by functioning as an autonomic antagonist.

Which of the following is least related to the innervation of skeletal muscle cells?

All voluntarily controlled muscle cells contain nicotinic, cholinergic receptors.

Which of the following selectively activates beta-2 receptors at low doses, making it possible to dilate bronchioles in the treatment of asthma?

Alpha and beta are two kinds of ____________________ receptors.

Indicate which type of neuron is associated with the characteristic by writing the appropriate letter in the blank using the answer code below. a.afferent and efferent neurons and interneurons b.afferent and efferent neurons c.afferent neurons d.efferent neurons e.interneurons f.none of the neurons -Carry information from the central nervous system

Atropine is an antagonist of ACh and works by
