37
Oculomotor nerve (CN III) innervation
Motor innervation: Superior rectus, medial rectus, inferior rectus, inferior oblique, levator palpebrae superioris
38
Trochlear nerve (CN IV) innervation
supplies the superior oblique muscle
39
Abducens nerve (CN VI) innervation
innervates lateral rectus muscle
40
Trigeminal nerve (CN V) innervation
innervates muscles of mastication
41
Facial nerve (CN VII) innervation
supplies tastes buds of the anterior two thirds of the tongue and soft palate, also innervates muscles of facial expression
42
Muscles of facial expression
Occipitofrontalis (raises eyebrows), Orbicularis oculi (closes one eye), orbicularis iris (makes kissy face)
43
Glossopharyngeal Nerve (CN 9) innervation
innervates the stylopharyngeal muscle and the parotid salivary gland, also provides sensation to posterior third of tongue
44
Spinal Accessory Nerve (CN XI) innervation
sternocleidomastoid and trapezius muscles
45
Hypoglossal Nerve (CN XII) innervation
innervates the intrinsic and extrinsic muscles of the tongue
46
Frontal Lobe
controls executive functions like concentration, thinking, problem solving and judgement: motivation, emotions, muscle strength, and behavior
47
Parietal Lobe
controls feeling on the opposite side of the body, ability to understand spoken language, ability to express yourself with language, and processing sensory information such as texture, temperature, and position in space
48
Occipital Lobe
controls sight and processing information from the eyes, such as recognizing images
49
Temporal Lobe
controls processing feelings of pain and hunger, fight-or-flight stress response, short-term memory, emotion, understanding words and directions
50
Brainstem
controls heart rate, breathing, blood pressure, swallowing and digestion. May also affect the nerves that come directly from the brain, movement, and the function of any senses
51
Cerebellum
balance and coordination of movement of the body; arms and legs
52
Pons
Holds important messages and sends them to the appropriate parts of your brain
53
Hippocampus
long-term memory formation and memory retrieval
54
Hypothalamus
Regulates body temperature, hunger, and thirst
55
signs of cranial nerve 3 lesion
dilated pupil; ptosis; eye turns "down and out," pupillary reflex on side of lesion will be lost
56
signs of cranial nerve 6 lesion
eye falls to move laterally; diplopia on lateral gaze
57
signs of cranial nerve 5 lesion
loss of pain and touch sensations; masseter and temporals muscles do not contract; deviation of mandible to side of lesion when mouth is opened
58
cranial nerve I lesion
loss of smell
59
cranial nerve II lesion
loss of pupillary constriction, visual field defects
60
cranial nerve IV lesion
inability to look down when eye is adducted
61
cranial nerve VII lesion
paralysis of facial muscles, loss of taste
62
cranial nerve VIII lesion
progressive unilateral hearing loss; tinnitus (noises in ear)
63
cranial nerve IX lesion
loss of taste of posterior third of tongue; loss of sensation on affected side of palate
64
cranial nerve X lesion
sagging of soft palate; deviation of uvula to normal side; hoarseness owing to paralysis of vocal fold
65
Cranial nerve XI lesion
Paralysis of sternocleidomastoid and descending fibers of trapezius; drooping of shoulder
66
Cranial nerve XII lesion
protruded tongue deviates toward affected side; disturbance of articulation
