1
CN V is also called the ______
 
trigeminal nerve
2
The three main divisions of the trigeminal nerve are:

7
The maxillary division is purely _______
 
sensory
8
The maxillary division (Vii) provides sensory input to:
 
upper jaw and teeth; maxillary paranasal sinus; hard and soft palates; nasal cavity; skin...
9
The mandibular division contains both _____ and ____ components
 
sensory and motor
10
Three main branches of the mandibular division are:
 
lingual, inferior alveolar, buccal
11
Lingual branch of mandibular division function:
 
sensory to anterior 2/3 of tongue; joined by chorda tympani branch of facial nerve which...
12
Inferior alveolar branch of the mandibular division function:
 
sensory to lower jaw and teeth and gums
13
Buccal branch of the mandibular division function:
 
sensory to skin of cheek
14
Trigeminal provides motor innervation to:
 
muscles of mastication: a) temporalis (b) masseter (c) medial pterygoid...
15
The trigeminal nucleus is the main _______
 
sensory nucleus
16
The trigenminal nucleus receives information containing:
 
discriminative touch and some proprioception from the head
17
The trigeminal nuclei is equivalent to the:
 
dorsal column nuclei of the spinal cord
18
Axons carrying  pain and temperature information  descend in the ______  as...
 
spinal trigeminal
19
Axons carrying pain and temp. info  terminate in the subjacent ________
 
spinal trigeminal nucleus
20
The spinal nucleus and tract of CN V are equivalent to _________________ of the spinal...
 
the substantia gelatinosa and Lissauer�s tract of the spinal cord
21
Spinal trigeminal nucleus also receives pain information from
 
CNs VII, IX and X
22
Efferent axons from trigeminal  nucleus join the crossed ventral ______ and...
 
trigeminothalamic tract
23
Cells in the mesenphalic nucleus are involved with ______ and are equivalent to________

processing information from muscle spindles of muscles of mastication
25
Muscles of mastication are involved with the _______ reflex
 
jaw jerk
26
The motor nucleus of trigeminal nerve supplies the  muscles of _____
 
medial and lateral pterygoids, masseter and temporalis, and also tensor tympani, tensor...
27
Clincal testing for trigeminal nerve (CN V) includes:

28
Trigeminal is responsible for the ___ component of the corneal blink reflex
 
sensory
29
The most common affliction affecting CNV is______
 
Trigeminal neulagia or tic doloreux
30
Effect of tic doloreux
 
Causes excruciating pain in one of the areas usually maxillary
31
Cause of tic doloreaux
 
Aberrant artery putting pressure on the sensory root as it leaves the pons
32
CN VII is also known as the _____
 
Facial nerve
33
___ is the largest nerve in the face
 
CN VII (facial nerve)

44
The parasympathetic components of the facial nerve include
 
lacrimal glands, sabmandivular and sublingual salivary glands
45
The special sensory component of the facial nerve deals with
 
taste on the anterrior 2/3 of tounge
46
Nuclei of CN VII include
 
Motor nuceli, nucleus solitarius and parasympathetic nuceli
47
The nuclues solitarius receives _____ information from CN IV (IX and X)
