(12 cards)
What is the function of the Olfactory nerve?
Transmits smell information from the nose to the brain
Olfactory nerve is responsible for the sense of smell.
What is the function of the Optic nerve?
Transmits visual information from the retina to the brain
The Optic nerve is crucial for vision.
What is the function of the Oculomotor nerve?
Provides motor control for the movement of the eyes, including constriction of the pupil
Oculomotor nerve controls most eye movements.
What is the function of the Trochlear nerve?
Eye movement via superior oblique muscles
Trochlear nerve controls the superior oblique muscle.
What is the function of the Trigeminal nerve?
Provides sensation to the face and controls muscles involved in chewing
Trigeminal nerve is the largest cranial nerve.
What is the function of the Abducens nerve?
Controls lateral rectus muscle, which moves the eye outward
Abducens nerve is responsible for lateral eye movement.
What is the function of the Facial nerve?
Controls muscles for facial expression and conveys taste sensation from the front two-thirds of the tongue
Facial nerve is involved in both motor and sensory functions.
What is the function of the Vestibulocochlear nerve?
Transmits sound and equilibrium (balance) information from the inner ear to the brain
Vestibulocochlear nerve is essential for hearing and balance.
What is the function of the Glossopharyngeal nerve?
Provides sensation from the back of the tongue/mouth & controls some muscles for swallowing
Glossopharyngeal nerve plays a role in taste and swallowing.
What is the function of the Vagus nerve?
Regulates parasympathetic functions (e.g., heart rate, digestion)
Vagus nerve is the longest cranial nerve.
What is the function of the Accessory nerve?
Controls shoulder and neck muscles
Accessory nerve is involved in head movement.
What is the function of the Hypoglossal nerve?
Controls movement of the tongue
Hypoglossal nerve is critical for speech and swallowing.
