Anatomy & Physiology

1. Anatomy & Physiology Lobes of the Brain Cranial Nerves

2. Lobes of the Brain • Frontal lobe • Top, front region • Responsible for emotions, reasoning, memory, judgment, speech • Parietal • Middle portion • Responsible for sensory & motor skills

3. Lobes of the Brain • Occipital • Back portion • Responsible for vision, reading ability • Temporal • Lower side of the brain • Responsible for hearing

4. Cranial Nerves

5. Cranial Nerves • Nerve I (Olfactory Nerve) • Smell • Test = Assess patency: occlude nostril & smell various smells • Nerve II (Optic Nerve) • Sight • Test = Assess peripheral vision (Confrontation test)

6. Cranial Nerves • Nerve III (Oculomotor) {Pupil contriction} • Nerve IV (Trochlear) {Down/Inward eye movement) • Nerve VI (Abducens) {Side to side eye movement} • Assess pupil constriction • 6 Cardinal Position of Gaze

7. Cranial Nerves • Nerve V (Trigeminal) • Motor function of temporal muscle & sensory of face • Test: Clench teeth test • Test: Assess sensory function – Cotton wisp

8. Cranial Nerves • Nerve VII (Facial nerve) • Motor function of face • Test: Facial symmetry • Test: Assess strength (activities)

9. Cranial Nerves • Nerve VIII (Acoustic nerve) • Hearing acuity • Test: Tuning fork test

10. Cranial Nerves • Nerve IX (Glossopharyngeal) • Nerve X (Vagus nerve) • Motor function (mouth, throat) • Test: Uvula test

11. Cranial Nerve • Nerve XI (Spinal Accessory) • Motor function of neck & shoulder muscles • Test: Assess strength of neck & shoulder muscles

12. Cranial Nerves • Nerve XII (Hypoglossal) • Motor function of the tongue • Test: Assess speech (light, tight, night)
