autonomic ganglia; visceral effectors

Which of the following is not a parasympathetic ganglion?

celiac

11) The statement ʺIt sends its preganglionic fibers to terminal or intramural gangliaʺ is

A) true only for the parasympathetic nervous system.

The statement ʺIt initiates contraction of urinary bladder smooth muscleʺ is

A) true only for the parasympathetic nervous system.

9) Which of the following is true for the craniosacral division?

B) It is also called the parasympathetic division of the ANS.

22) Splanchnic nerves

B) consist of axons that synapse in collateral ganglia.

12) Collateral ganglia contain neurons that innervate tissues and organs in which cavity?

C) abdominopelvic

23) Sympathetic innervation of the urinary bladder is by way of the ________ ganglion.

C) inferior mesenteric

) Clusters of ganglionic sympathetic neurons lying along either side of the spinal cord are called sympathetic ________ ganglia.

Chain

10) Cell bodies of preganglionic neurons of the autonomic nervous system are located

D) both in the brain stem and in the lateral gray horns of the spinal cord.

24) The sympathetic collateral ganglia include all of the following except the

D) lumbar

Preganglionic fibers of parasympathetic neurons are present in all of the following cranial nerves only

III, VII, IX, X

Specialized ganglionic sympathetic neurons that release hormones into the bloodstream are found within the

adrenal glands.

Clusters of ganglionic sympathetic neurons that innervate organs in the abdominopelvic region are called ________ ganglia.

collateral

Autonomic motor neurons

conduct impulses to smooth and cardiac muscles and glands.

) Injury to the neurons of a collateral ganglion would affect the function of the

digestive tract

Preganglionic fibers leave the CNS and then synapse on

ganglionic neurons.

The celiac ganglia do not innervate the

intestines

The ________ division of the autonomic nervous system is known as the ʺrest and digestʺ division

parasympathetic

Intramural ganglia in the large intestine, urinary bladder, and reproductive organs are innervated by the ________ nerves.

pelvic

A visceral motor neuron whose cell body is within the CNS is called a(n) ________ neuron

preganglionic

Sympathetic and parasympathetic fibers that innervate the heart pass through the

pterygopalatine ganglia.

Ganglionic neurons innervate as all of the following except

skeletal muscle.

All of the following are visceral effectors except

skeletal muscles.

Preganglionic fibers that innervate the collateral ganglia form the

splanchnic nerves.

Postganglionic fibers that innervate targets in the body wall or thoracic cavity originate on neurons within

sympathetic chain ganglia

The sympathetic division of the ANS is also known as which of the following?

thoracolumbar division

The statement ʺThere is always a synapse in a peripheral ganglion between the CNS and the effector organʺ is

true for both the parasympathetic and sympathetic nervous systems

The statement ʺIts ganglia are usually near or within the end organʺ is

true only for the parasympathetic nervous system.

Almost 75 percent of all parasympathetic outflow travels along the ________ nerve(s).

vagus
