What is the function of the Olfactory nerve (CN I)?
The Olfactory nerve is responsible for the sense of smell.
What is the primary function of the Optic nerve (CN II)?
The Optic nerve transmits visual information from the retina to the brain.
True or False: The Oculomotor nerve (CN III) controls eye movement and pupil constriction.
True
What functions does the Trochlear nerve (CN IV) perform?
The Trochlear nerve innervates the superior oblique muscle, enabling downward and lateral eye movement.
Which cranial nerve is responsible for sensation in the face and motor functions such as biting and chewing?
The Trigeminal nerve (CN V) is responsible for sensation in the face and motor functions for biting and chewing.
List the three branches of the Trigeminal nerve (CN V).
The three branches are the Ophthalmic nerve (V1), Maxillary nerve (V2), and Mandibular nerve (V3).
What is the function of the Abducens nerve (CN VI)?
The Abducens nerve controls the lateral rectus muscle, allowing for lateral eye movement.
Fill in the blank: The Facial nerve (CN VII) is responsible for _____ and the sense of taste from the anterior two-thirds of the tongue.
facial expressions
True or False: The Vestibulocochlear nerve (CN VIII) is involved in hearing and balance.
True
What are the two components of the Vestibulocochlear nerve (CN VIII)?
The two components are the cochlear nerve (for hearing) and the vestibular nerve (for balance).
What is the function of the Glossopharyngeal nerve (CN IX)?
The Glossopharyngeal nerve is involved in taste from the posterior one-third of the tongue, swallowing, and salivation.
What is the role of the Vagus nerve (CN X)?
The Vagus nerve controls autonomic functions of the heart, lungs, and digestive tract, and provides sensation to the throat.
True or False: The Accessory nerve (CN XI) is responsible for shoulder shrugging and head turning.
True
What is the primary function of the Hypoglossal nerve (CN XII)?
The Hypoglossal nerve controls tongue movements.
Which cranial nerve has both sensory and motor functions?
The Trigeminal nerve (CN V) has both sensory and motor functions.
Fill in the blank: The Oculomotor nerve (CN III) also controls the _____ muscle for pupil constriction.
sphincter
What is the function of the Facial nerve (CN VII) in relation to taste?
The Facial nerve carries taste sensations from the anterior two-thirds of the tongue.
Which cranial nerve is solely responsible for hearing?
The cochlear component of the Vestibulocochlear nerve (CN VIII) is solely responsible for hearing.
What sensory function is associated with the Glossopharyngeal nerve (CN IX)?
The Glossopharyngeal nerve is associated with the sensation of taste from the posterior one-third of the tongue.
True or False: The Vagus nerve (CN X) only has motor functions.
False
What is the unique feature of the Accessory nerve (CN XI)?
The Accessory nerve has both cranial and spinal components, innervating the sternocleidomastoid and trapezius muscles.
Which cranial nerve is responsible for the movement of the eye muscles?
The Oculomotor nerve (CN III), Trochlear nerve (CN IV), and Abducens nerve (CN VI) are responsible for eye muscle movement.
Fill in the blank: The Trigeminal nerve (CN V) branches into three parts: V1, V2, and V3, which are responsible for _____ in the face.
sensation
What is the function of the Vestibular nerve component of the Vestibulocochlear nerve (CN VIII)?
The Vestibular nerve is responsible for balance and spatial orientation.
