Exam 9: The Autonomic Nervous System

The ___________________________ are branches made from the myelinated preganglionic sympathetic axons that go from the spinal nerves to sympathetic ganglia chain.

Damage to the thoracic and lumbar regions of the spinal cord would cause heart rate to be chronically increased compared to normal.

Damage to the _____________ nerve would inhibit salivary production.

Bradykinin stimulates

_____________ is released by most postganglionic sympathetic nerves.

All adrenergic receptors act via

Intracellular Ca²⁺ is elevated if norepinephrine binds to a(n)_____________ receptor.

The paravertebral and collateral ganglia are associated with the _____________ division of the autonomic nervous system.

The vagus nerve would innervate all of the following except

Damage to the paravertebral ganglia would limit the body's ability to respond to stress.

The sympathetic division of the autonomic nervous system has limited range because only a few postganglionic neurons are stimulated.

Adrenergic receptors are found on the surface of postganglionic sympathetic neurons.

____________ fibers have relatively slower nerve conduction because they are thin and unmyelinated.

Phenylephrine functions as a _______ because it promotes vasodilation in nasal mucosa.

___________ selectively stimulates a₂ receptors in brain neurons thereby suppressing sympathoadrenal activation and lowering blood pressure.

Which of the following organs is dually innervated?

Blood flow to skeletal muscle would be _____________ in response to muscarinic antagonists.

Fibers that secrete norepinephrine are called adrenergic fibers.

The sympathetic chain ganglia are found laterally on both sides of the spinal cord.

Goose bumps would occur in response to
