A&P 1 final

Question 1

The two divisions of the autonomic nervous system are

Answer 1

sympathetic division and the parasympathetic division

Question 2

The sympathetic system is associated with the fight-or-flight response, and parasympathetic activity is referred to by the epithet of

Answer 2

rest and digest

Question 3

The sympathetic system is associated with the

Answer 3

fight-or-flight response

Question 4

the balance between the two systems.

Answer 4

Homeostasis

Question 5

The sympathetic division of the autonomic nervous system influences the various organ systems of the body through connections emerging from the thoracic and upper lumbar spinal cord. It is referred to as

Answer 5

Thoracolumbar system

Question 6

in the lateral horn of any of these spinal regions projects to ganglia adjacent to the vertebral column through the ventral spinal roots.

Answer 6

central neuron

Question 7

The majority of ganglia of the sympathetic system belong to a network of

Answer 7

sympathetic chain ganglia

Question 8

The first type is most direct: the sympathetic nerve projects to the chain ganglion at the same level as the

Answer 8

target effector

Question 9

An example of this type is spinal nerve T1 that synapses with the T1 chain ganglion to innervate the trachea. The fibers of this branch are called

Answer 9

White rami communicants

Question 10

The axon from the central neuron (the preganglionic fiber shown as a solid line) synapses with the

Answer 10

ganglionic neuron

Question 11

This neuron then projects to a target effector—in this case, the trachea—via

Answer 11

Gray rami communications which are unmyelinated axons.

Question 12

neuron. An example of this is spinal nerve T1 that innervates the eye. The spinal nerve tracks up through the chain until it reaches the

Answer 12

cervical ganglion

Question 13

Ganglia, which are part of the sympathetic chain ganglia, are also called the

Answer 13

paravertebral ganglia

Question 14

Additional branches from the ventral nerve root continue through the chain and on to one of the collateral ganglia as the

Answer 14

greater splanchnic nerve or lesser splanchnic nerve

Question 15

are situated anterior to the vertebral column and receive inputs from splanchnic nerves as well as central sympathetic neurons.

Answer 15

collateral or prevertebral ganglia
