Exam 34: Nervous System

Eyesight is supplied by cranial nerves II and III.

The sympathetic nervous system is also known as the craniofacial outflow.A term commonly used to describe the sympathetic nervous system is the "fight-or-flight mechanism."

Sensation to the maxillary labial gingiva is supplied by the nasopalatine nerve because this nerve branches off the infraorbital as it travels to supply the maxillary anterior teeth.

The autonomic nervous system is composed of preganglionic and postganglionic neurons.These neurons diverge (separate)in a ganglion within the nervous system.

When the tip of the tongue feels pain from hot soup,the lingual division of the facial nerve is innervated because the lingual nerve supplies sensation to the anterior two-thirds of the tongue.

Which nerve supplies muscle that moves the eye downward and laterally?

Sensation to the skin of the mandibular lip and chin is supplied by which nerve?

During times of stress incoming light is blocked to protect the eyes.This is accomplished by dilation of the pupils,a function of the sympathetic nervous system.

Which of the following accurately describe functions of the brain (Select all that apply. )?

The facial nerve innervates each of the following structures EXCEPT one.Which one is the EXCEPTION?

The maxillary division of the trigeminal nerve follows the same pathway as the maxillary artery.The maxillary nerves and arteries generally have the same names.

The central nervous system is made up of the brain and the spinal cord.

The olfactory nerve has sensory and motor functions.

Each of the following cranial nerves has sensory function EXCEPT one.Which one is the EXCEPTION?

Which nerve goes up into the orbit and exits to supply the skin of the cheek and temple?

Which part of the spinal cord is arranged in the shape of a butterfly?

The olfactory and optic are the only cranial nerves that are not paired because they are centrally located in the intravertebral foramina.

An intercalated neuron is a shorter neuron that runs between the two neurons.

The mental nerve supplies sensation to the floor of the mouth,the lingual mandibular gingivae,and the anterior two-thirds of the tongue.The mental nerve is joined by the chorda tympani,a branch of the facial nerve,to supply the submandibular and sublingual salivary glands.

The tenth cranial nerve has motor innervations to the root of the tongue and epiglottis.It supplies both motor and sensory innervation to muscles of the pharynx and larynx.
