All of the following characterize the ANS except:
Innervation of skeletal muscles
Presence of nerve cell bodies in ganglia
Presence of nerve cell bodies in CNS
Two-neuron efferent chain
Which pair is correctly matched?
ACh: Acetylcholine
NE: Norepinephrine
Parasympathetic Postganglionic Axon; Release ACh
Parasympathetic Preganglionic Axons; Release NE
Sympathetic Postganglionic Axons; Release NE
Sympathetic Preganglionic Axons; release NE
Which don't have nicotinic receptors of the neuronal type?
Parasympathetic postganglionic neurons
Sympathetic postganglionic neurons
Adrenal medulla cells
Parasympathetic preganglionic neurons
The majority of preganglionic parasympathetic fibers are housed within which cranial nerve?
Facial
Vagus
Oculomotor
Glossopharyngeal
Predict the outcome of an experiment in which adrenal medulla cells are treated with nicotine
The adrenal medulla is inhibited by nicotine
Blood levels of epinephrine & norepinephrine decrease
Blood levels of acetylcholine increase
Blood levels of epinephrine & norepinephrine increase
Fibers that release acetylcholine and called ____ fibers, whereas those that release norepinephrine are called ____ fibers
Cholinergic, adrenergic
Somatic, autonomic
Adrenergic, cholinergic
Sensory, somatic
Which receptor type and its location is correctly matched?
B1: heart
B2: adipose tissue
B3: lungs
A1: pancreas
A2: blood vessels serving the skin
The sympathetic division is involved in which of the following processes
Increasing glucose metabolism
Decreasing urinary output
Regulating blood pressure
Decreasing urinary output
Which area of the body receives no innervation by the parasympathetic nervous system?
Sweat glands
Adrenal medulla
Kidneys
Blood vessels
Arrecti pili muscles
Regulation of heart rate at low normal levels is achieved by the ____
Sympathetic Divison
Parasympathetic Division
Somatic Division
As far as cooperative effects between the ANS within the reproductive system, the arousal phase is controlled by the ____ division while the orgasmic phase by the ____ division.
Sympathetic, parasympathetic
Somatic, sensory
Parasympathetic, sympathetic
Parasympathetic, somatic
How is it possible that norepinephrine can cause vasoconstriction in one location but vasodilation in another?
Norepinephrine is not released by the PNS
It can't, its actions are predictable no matter the issue
Receptor types differ in these tissues
Sometimes norepinephrine is released by the Parasympathetic NS, which causes relaxation
Asthma patients suffer from attacks in which bronchiole smooth muscle constricts, making it hard to breathe. Albuterol, a common asthma medication, works via which of the following steps?
Binds to nicotinic receptors & inhibits epinephrine release
Binds to B2-andrenergic receptors to enhance vasodilation
Binds to B2-andrenergic receptors to inhibit vasodilation
Binds to and stimulates muscarinic receptors
In general, sympathetic innervation of visceral organs via the lumbar & sacral splanchnic nerves inhibits the activity of these organs. This is logical because ____
Sympathetic activity primes the body for physical activity & temporarily shuts down noncritical body activities
Sympathetic input is always inhibitory
Sympathetic input primes the body to enter a resting state
Parasympathetic innervation is lacking from this area
