      • I- Olfactory Nerve: Sensory; Responsible for smell. Lesions may cause anosmia (loss of smell) and parosmia (distorted smell).
      • II- Optic Nerve: Sensory; Responsible for vision. Lesions may result in decreased visual acuity and field defects.
      • III, IV, VI- Ocular Nerves (Occulomotor, Trochlear, and Abducent): Motor and Autonomic (for eye movement). Lesions can lead to diplopia (double vision).
      • V - Trigeminal Nerve: Sensory and Motor; Responsible for facial sensation, mastication, and jaw movement. Lesions may cause difficulty in mastication, abnormal facial sensation, and decreased jaw movement.
      • VII - Facial Nerve: Sensory, Motor, and Autonomic; Responsible for facial expression, taste, and tear production. Lesions may cause facial drooping, difficulty with taste, and decreased tear production.
      • VIII - Cochleo-Vestibular Nerve: Sensory; Responsible for hearing and balance. Lesions may cause hearing loss, tinnitus (ringing in the ears), and vertigo (dizziness).
      • IX - Glossopharyngeal Nerve: Sensory, Motor, and Autonomic; Responsible for taste, gag reflex, and swallowing. Lesions may cause difficulties with swallowing, dysarthria (difficulty speaking), dysphonia (hoarseness), and nasal regurgitation.
      • X - Vagus Nerve: Sensory, Motor, and Autonomic; Responsible for gag reflex, voice, and parasympathetic function. Lesions may lead to dysphonia, impaired swallowing, and nasal regurgitation.
      • XI - Accessory Nerve: Motor; Responsible for shoulder movement and head rotation. Lesions may cause weakness in shoulder movement and head rotation.
      • XII - Hypoglossal Nerve: Motor; Responsible for tongue movement. Lesions may cause tongue weakness, difficulty speaking, and tongue deviation.
    • Motor Assessment: Focus on the following elements for proper motor assessment:
      • Observation:
        • State of muscle: Examine whether muscle is normal, wasted (atrophy), or hypertrophied.
        • Muscle wasting: Describe wasting in detail.
          • Affected region
          • Unilateral or bilateral
          • Symmetrical vs. asymmetrical
          • Distal vs. Proximal
        • Muscle hypertrophy: Distinguish between true and pseudo hypertrophy.
          • True hypertrophy: Increase in muscle size AND strength.
          • Pseudo hypertrophy: Increase in muscle size BUT decreased strength (common in myopathy).
        • Fasciculation or fibrillation: Indications of an irritative motor neuron disorder.
          • Fibrillation: Spontaneous contraction of a single muscle fiber (hardly visible).
          • Fasciculation: Spontaneous contraction of a group of muscle fibers (visible and palpable).
        • Involuntary movements: Describe chorea (uncontrollable jerking movements), athetosis (slow writhing movements), and tremors in detail.
          • Static or dynamic: Does the movement occur at rest or during movement?
          • Rhythmic or arrhythmic:
          • What increases/decreases them: Note factors influencing the movements.
      • Muscle Power: Assess the strength of specific muscle groups.
      • Muscle Tone: Evaluate the resistance to passive movement.
      • Reflexes: Perform both superficial and deep tendon reflexes.
      • Range of Motion (ROM): Measure the flexibility of joints.
    • Muscle Tone Assessments:
      • Methods:
        • Shaking
        • Drop arm test
        • Speed test
        • Gower's method
        • EMG biofeedback
        • Passive movement
      • Shaking Methods:
        • Used for distal joints (wrist and ankle).
        • Hold the limb above the joint and shake it.
        • Hypertonia: Decreased resistance to shaking.
        • Normal tone: Normal resistance to shaking.
        • Hypotonia: Increased resistance to shaking.
      • Drop arm test:
        • Assess shoulder flexion or abduction.
        • Start with the arm at 90 degrees.
        • Release the arm.
        • Normal: Initial drop followed by catching.
        • Hypotonia: Sudden drop.
        • Hypertonia: Slow descent or no descent.
      • Speed test: Evaluates resistance to movement.
      • Gower's method:
        • Assess shoulder joint movement in myopathy.
        • Elevate the patient's shoulders by grasping under the axilla.
        • Normal: Shoulders reach ear level.
        • Hypotonia: Shoulders elevate higher than normal, head drops between shoulders.
      • EMG biofeedback: An objective measurement of muscle tone using H/M ratio.
        • Normal H/M ratio: Around 1.
        • Spasticity: Increased H/M ratio.
      • Passive movement: Measure the resistance to passive movement.
    • Important distinctions in motor assessment:
      • Upper Motor Neuron (UMN) lesions:
        • Distal more than proximal.
        • Antigravity muscles affected (flexors of upper limbs and extensors of lower limbs).
        • Hyperreflexia.
      • Lower Motor Neuron (LMN) lesions:
        • Proximal more than distal.
        • Both muscle groups affected (but flexors more than extensors).
        • Hyporeflexia.
