Which of the following nerves can also serve as an afferent nerve for the
mandibular first molar, thus complicating dental local anesthesia?
a. Posterior superior alveolar nerve
b. Infraorbital nerve
c. Mental nerve
d. Inferior alveolar nerve
e. Mylohyoid nerve
Mylohyoid nerve
the mylohyoid nerve may in some cases also serve as an afferent nerve for the
mandibular first molar, which needs to be considered when the inferior alveolar
block fails, thus complicating dental local anesthesia.
The fluid outside of the nerve membrane has a positive charge; the fluid inside
has a negative charge, producing a change difference or
a. resting potential.
b. synapse.
c. anastomosis.
d. action potential.
e. neurotransmitter.
resting potential
the fluid outside of the nerve membrane has a positive charge; the fluid inside has
a negative charge, producing a charge difference or resting potential.

Which of the following nerves travels through the parotid salivary gland and thus
can be injured with a malignant neoplasm of the gland?
a. Trigeminal nerve
b. Maxillary nerve
c. Mandibular nerve
d. Ophthalmic nerve
e. Facial nerve
Facial nerve;
if cancer or malignant neoplasm occurs within the parotid salivary gland, the facial
nerve or seventh cranial nerve can be injured because it travels through the gland
causing extreme unilateral facial pain.
In which of the following conditions is there a loss of muscular action of the
muscles of facial expression such as occurs secondarily to a cerebrovascular
accident?
a. Facial paralysis
b. Bell palsy
c. Anesthesia
d. Alzheimer disease
e. Trigeminal neuralgia
Facial paralysis;
facial paralysis is the loss of muscular action of the muscles of facial expression
such as occurs secondarily to a cerebrovascular accident or stroke.
What is the loss of feeling or sensation resulting from the use of certain drugs or
gases that serve as inhibitory neurotransmitters?
a. Paralysis

b. Anesthesia
c. Xerostomia
d. Hypersalivation
e. Muscular hypertrophy
Anesthesia;
anesthesia is the loss of feeling or sensation resulting from the use of certain
drugs or gases that serve as inhibitory neurotransmitters.
Which of the following mimic inhibitory neurotransmitters by decreasing sensory
neurons' ability to generate an action potential?
a. Lidocaine
b. Heparin
c. Penicillin
d. Thyroxine
e. Vasoconstrictor
Lidocaine;
many local anesthetic agents such as lidocaine, as used in dentistry, mimic
inhibitory neurotransmitters by decreasing sensory neurons' ability to generate an
action potential, thus producing localized anesthesia.
Which of the following is a neurotransmitter that blocks the uptake of
norepinephrine while stimulating the uptake of dopamine?
a. Lidocaine
b. Cocaine
c. Penicillin
d. Sulfa
e. Prilocaine

, Orofacial 2 final exam
Cocaine
among the drugs that affect neurotransmitter function is cocaine, which blocks
the uptake of norepinephrine while stimulating the uptake of dopamine.
The brainstem of the CNS contains which of the following structures?
Medulla, pons and midbrain
Which of the following is a correct statement concerning neurotransmitters within
the nervous system?
a. discharge with the arrival of action potential
b. bind to RBC to prompt transmission of impulses
Discharge with the arrival of action potential
An efferent nerve within the nervous system is known to carry information
Away from the brain or spinal cord to the periphery of the body
Which structures do the posterior superior alveolar nerve and its branches
innervate?
Maxillary molars
Which foramina does the facial nerve pass through the skull?
Stylomastoid foramen
Which cranial nerve is directly involved with bell palsy?
Facial nerve
Which of the following nerve pairs is correct?
a. long buccal nerve-buccinator muscle
b. accessory nerve-platysma muscle
c. hypoglossal nerve-intrinsic tongue muscle
d. auriculotemporal nerve-temporalis muscle
