cranial nerves

What is the main function of the Hypoglossal nerve in swallowing?

• Controls eye movements
• Controls tongue movements for safe food passage
• Coordinates lip movements
• Regulates breathing

What is the consequence of damage to the Hypoglossal nerve in terms of speech production?

• Difficulty swallowing
• Loss of taste sensation
• Slurred or unclear speech
• Clear articulation

Which nerve is responsible for controlling the muscles of mastication (chewing)?

• Ophthalmic nerve (V1)
• Maxillary nerve (V2)
• Facial nerve (VII)
• Mandibular nerve (V3)

Which cranial nerve is purely motor and controls the muscles of the tongue?

• Vagus nerve (X)
• Hypoglossal nerve (XII)
• Glossopharyngeal nerve (IX)
• Facial nerve (VII)

What is the consequence of damage to the Trigeminal nerve in terms of chewing?

• Loss of taste sensation
• Difficulty swallowing
• Impaired coordination of chewing muscles
• Slurred speech

Which nerve is responsible for innervating the lower jaw, teeth, and lower lip?

• Ophthalmic nerve (V1)
• Facial nerve (VII)
• Maxillary nerve (V2)
• Mandibular nerve (V3)

What is the role of the Trigeminal nerve in the blink reflex?

• Controls eye movement

• Coordinates lip movements

What is the primary sensory function of the Trigeminal nerve?

• Smell sensation
• Taste sensation
• Hearing sensation
• Touch, pressure, pain, and temperature sensations
