Exam 7: The Peripheral Nervous System: Efferent Division

The sympathetic postganglionic fibers that innervate the sweat glands secrete acetylcholine rather than norepinephrine.

An EPP is a graded potential.

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 -Innervates voluntary muscle cells

Which organ is not innervated by the parasympathetic division?

Match the chemical with correct characteristic. a.myasthenia gravis b.black widow spider venom c.curare d.Clostridium botulinum toxin e.organophosphates -Causes explosive release of ACh.

The sympathetic nervous system causes

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 -Lie within the peripheral nervous system

The salivary glands and the eye are sympathetically innervated by cranial nerves.

Neuron 3

The axons controlling skeletal muscles are large and myelinated.

The parasympathetic nervous system

By blocking the effect of acetylcholine at muscarinic but not nicotinic receptors, atropine is able to block parasympathetic effects.

Sympathetic dominance would be most likely responsible for erection.

Which of the following does not characterize the sympathetic nervous system?

Sympathetic stimulation ____ heart rate and ____ the motility in the digestive tract.

Indicate the characteristics of the types of autonomic receptors using the following answer code: a.nicotinic receptors b.muscarinic receptors c.alpha receptors d.beta-1 receptors e.beta-2 receptors f.alpha-1 and beta-1 receptors g.muscarinic, alpha, beta-1, and beta-2 receptors -Have equal affinity for epinephrine and norepinephrine

Indicate which part of the autonomic nervous system is being described by writing the appropriate letter in the blank using the following answer code. a.sympathetic nervous system b.parasympathetic nervous system c.both sympathetic and parasympathetic nervous system d.neither sympathetic nor parasympathetic nervous system -Innervates smooth muscle, cardiac muscle, and exocrine glands

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 -Innervates the adrenal cortex

The two divisions of the autonomic nervous system are the ____________________ nervous system, which dominates in fight-or-flight situations, and the ____________________ nervous system, which dominates in quiet, relaxed situations.

Indicate which part of the autonomic nervous system is being described by writing the appropriate letter in the blank using the following answer code. a.sympathetic nervous system b.parasympathetic nervous system c.both sympathetic and parasympathetic nervous system d.neither sympathetic nor parasympathetic nervous system -Has a long preganglionic fiber and a short postganglionic fiber
