Study Notes
Cranial Nerve Functions
- Cranial Nerve I (Olfactory): responsible for smell, performs Smell Test
- Cranial Nerve II (Optic): responsible for visual acuity and fields, performs Visual Acuity and Fields Test
- Cranial Nerve III (Oculomotor): responsible for pupillary response and eye movements (EOMs)
- Cranial Nerve IV (Trochlear): responsible for eye movements (EOMs), especially downward gaze
- Cranial Nerve V (Trigeminal): responsible for facial sensation and muscles of mastication
- Cranial Nerve VI (Abducens): responsible for lateral gaze
- Cranial Nerve VII (Facial): responsible for facial movements and taste (anterior 2/3 of tongue)
- Cranial Nerve VIII (Vestibulocochlear): responsible for hearing and balance tests
- Cranial Nerve IX (Glossopharyngeal): responsible for gag reflex and taste (posterior 1/3 of tongue)
- Cranial Nerve X (Vagus): responsible for gag reflex, voice quality, and visceral reflexes
- Cranial Nerve XI (Spinal Accessory): responsible for shoulder shrug and head turn against resistance
- Cranial Nerve XII (Hypoglossal): responsible for tongue movement
Eye Assessment
- Nystagmus: involves Cranial Nerve VIII (vestibulocochlear nerve) and related nerves (III, IV, and VI); abnormal finding: involuntary rhythmic shaking or oscillation of the eyes
- Corneal Reflex: involves Cranial Nerve V (trigeminal nerve) and Cranial Nerve VII (facial nerve); abnormal finding: absence or asymmetry of blinking response
Cerebellar Function Tests
- Balance Test: abnormal findings include loss of balance, unsteady gait, inability to walk straight, or requiring a wide base to stand
- Romberg Test: abnormal findings include swaying or falling when eyes are closed, indicating proprioceptive or vestibular dysfunction
- Rapid Alternating Movements (RAM): tests cerebellar function, specifically the ability to perform rapid, alternating movements smoothly
- Finger-to-Nose Test: tests coordination and precision of movements, pointing to cerebellar function or proprioceptive feedback
- Heel-to-Shin Test: tests lower limb coordination and the ability to perform smooth, accurate movements
Tactile Discrimination and Reflexes
- Stereognosis: ability to recognize and identify common objects by touch and manipulation without visual input; abnormal finding: inability to recognize objects by touch
- Graphesthesia: ability to recognize writing on the skin purely by sensation of touch; abnormal finding: difficulty in recognizing writing on the skin
- Two-point Discrimination: ability to discern two distinct points when simultaneously applied to the skin at close proximity; abnormal finding: inability to distinguish two nearby points
- Extinction: failure to perceive touch on one side when both sides are touched simultaneously
- Point Location: ability to accurately indicate where a point on the skin was touched after the stimulus is removed; abnormal finding: difficulty in identifying the exact point touched
Reflexes
- Deep Tendon Reflexes (DTRs): tests the integrity of spinal cord segments and corresponding nerve tracts, using a 4-point scale
- Superficial Reflexes: tests the function of higher brain centers and the spinal cord
- Visceral Reflexes: tests the autonomic nervous system and involves smooth muscle responses rather than skeletal muscle
- Pathologic (Abnormal) Reflexes:
- Clonus: indicates disruption of motor tracts, typically within the central nervous system
- Dyskinesia: represents a dysfunction in the basal ganglia circuits, affecting voluntary motor movements and procedural learning### Biceps Reflex (C5-C6)
- Supports person's forearm on yours
- Places thumb on biceps tendon and strikes a blow
- Normal response: contraction of biceps muscle and flexion of forearm
Triceps Reflex (C7-C8)
- Tells person to let arm "just go dead"
- Strikes triceps tendon directly just above the elbow
- Normal response: extension of forearm
Brachioradialis Reflex (C5-C6)
- Holds person's thumbs to suspend forearms in relaxation
- Strikes forearm directly, 2-3 cm above radial styloid process
- Normal response: flexion and supination of forearm
Quadriceps Reflex (L2-L4, "Knee Jerk")
- Lets lower legs dangle freely to flex knee and stretch tendons
- Strikes tendon directly just below patella
- Normal response: extension of lower leg
Achilles Reflex (L5-S2, "Ankle Jerk")
- Positions person with knee flexed
- Holds foot in dorsiflexion and strikes Achilles tendon directly
- Normal response: foot plantar flexes against your hand
Superficial Reflexes - Abdominal Reflexes
- Tests four quadrants: upper and lower on each side
- Normal finding: abdominal muscles contract, and umbilicus moves towards the stimulus when the skin of the abdomen is lightly stroked
- Abnormal finding: absence of contraction of the abdominal muscles and movement of the umbilicus in response to stroking the skin
