Study Notes
Cranial Nerves
- Olfactory (I): Smell
- Optic (II): Sight
- Oculomotor (III): Opening of eyelid, pupil constriction, focusing
- Trochlear (IV): Eye movement
- Trigeminal (V): Touch, sensations from face
- Abducens (VI): Lateral eye movement
- Facial (VII): Facial expressions, tears, saliva, taste
- Vestibulocochlear (VIII): Hearing
- Glossopharyngeal (IX): Taste, touch, pressure, temperature sensations
- Vagus (X): Taste, gastrointestinal discomfort, swallowing, speech
- Accessory (XI): Shoulder shrug, larynx movement during swallowing
- Hypoglossal (XII): Tongue movement, speech, swallowing
Receptor Classification
- Chemoreceptors: Respond to chemicals (e.g., odors, tastes, glucose, carbon dioxide)
- Mechanoreceptors: Respond to changes in position (e.g., pressure, stretch, vibrations)

Description
This quiz focuses on the twelve cranial nerves and their functions, as well as the two main types of receptors: chemoreceptors and mechanoreceptors. Test your knowledge on the sensory systems and the vital roles these nerves play in our daily activities.
