PERIPHERAL NERVOUS SYSTEM- Cranial Nerves 1) What
are they?
2) What are the cranial nerves which are exclusively sensory?
3) Which nerve is both sensory and motor?
4) Which nerve is primarily a motor nerves?
5) Which nerve is a primary concern with local anesthesia? - ANSWER 1)
Nerves that start at the base of the brain. 2) Optic nerve (sight),
Olfactory nerve (smell), Auditory nerve (sound).
3) Trigeminal nerve, which supplies sensation to teeth and jaw, and has a
motor branch which supplies the muscles of mastication.
4) Facial nerve, supplies motor fibers for facial expression such
as smiling, frowning, etc.
5) Trigeminal nerve
CRANIAL NERVE, TRIGEMINAL NERVE: Mandible 1) What
are the 3 branches of the nerve?
2) What nerves are anesthetized when working on the mandible?
What is this injection called?
3) What areas does this affect? - ANSWER 1) Opthalmic, Maxillary, and
Mandibular.
2) Inferior alveolar and lingual nerves. Mandibular block. 3) Mandibular
teeth, chin, lips, half of the tongue, and the floor of the mouth.
CRANIAL NERVE, TRIGEMINAL NERVE: Maxilla
1) If teeth are not infiltrated individually, what types of blocks can be
used?
2) What do each of these nerves supply? - ANSWER 1) Posterior
superior alveolar, greater palatine, and nasopalatine.
2) Posterior Superior Alveolar- posterior portion of the maxilla.
Greater Palatine- posterior palate. Nasopalatine- anterior palate.
, AUTONOMIC NERVOUS SYSTEM:
1) What does this regulate? What is this regulation called?
2) What has this system also been called?
3) What are the two subdivisions of this system? - ANSWER 1) It adjusts
functions of the organs to keep the body in a constant state, such as
blood pressure, heart rate, breathing, body temperature, water balance,
etc. This is called homeostasis.
2) Involuntary or automatic nervous system.
3) Sympathetic and parasympathetic.
AUTONOMIC NERVOUS SYSTEM, Sympathetic Nervous
System:
1) What does this system do?
2) What important thing does this system maintain? How does it do
this?
3) What chemical does this system use to cause action? What is this a
close relative of?
4) What are the effects of this system sometimes called? - ANSWER 1)
It prepared the body for intense physical activity in response to stress.
2) The blood pressure. The sympathetic system in the medulla maintains
vasoconstrictor tone, which controls blood vessel diameter.
3) Norepinephrine, closely related to epinephrine or adrenaline.
4) Adrenergic. (adrenaline!)
AUTONOMIC NERVOUS SYSTEM, Sympathetic Nervous System:
1) What are the two subgroups of this system?
2) What are the two sections of the second subgroup? - ANSWER 1)
Alpha (vasoconstriction of arteries and veins) and Beta (big organs)
2) #1- Heart, increases heart rate and strength of contractions. #2 Lung,
causes bronchodilation.
PARASYMPATHETIC NERVOUS SYSTEM:
1) What does this system do?
2) What chemical does this system use? What are the actions of this
system called?
