Which of the following is true in respect to the innervation of the tongue? a) The chorda tympani nerve innervates the anterior two-thirds of the tongue in respect to special sensation (taste). b) The lingual nerve innervates the posterior one-third of the tongue in respect to general sensation (touch and temperature). c) The lingual nerve innervates the posterior one-third of the tongue in respect to special sensation (taste). d) The glossopharyngeal nerve innervates the area of the tongue just anterior to the epiglottis in respect to both general and special sensation. e) The chorda tympani nerve innervates the mucosa of the anterior two-thirds of the tongue in respect to general sensation (touch and sensation).

Which best describes the tongue, ears, and nose? A) sense organs that are part of the central nervous system B) sense organs that are part of the peripheral nervous system C) internal organs that are part of the central nervous system D) internal organs that are part of the peripheral nervous system
The vagus nerve innervates the digestive system, muscles of the neck, thorax, and the heart. True False Large myelinated nerve fibers have a slower rate of conduction than small unmyelinated nerve fibers. A. False B. True Photoreceptors, in the eyes, respond to light but one can actually see because of the visual center located in the frontal lobe of the cerebellum. True False Under normal everyday conditions, the sympathetic division of the autonomic nervous system regulates the viscera. True False The eye muscles are innervated by the oculomotor, trochlear, and abducens cranial nerves. True False The lacrimal gland is located superior and lateral to the eye. False True
