More specifically. the vestibular branch carries impulses for equilibrium and the cochlear branch carries impulses for hearing.; Located in internal acoustic canalIXGlossopharyngeal nerveBoth Sensory and MotorMedullaNucleus ambiguus, Inferior salivary nucleus, Solitary nucleusReceives taste from the posterior 1/3 of the tongue, provides secretomotor innervation to the parotid gland, and provides motor innervation to the stylopharyngeus (essential for tactile, pain, and thermal sensation)[citation needed]. Some sensation is also relayed to the brain from the palatine tonsils. Sensation is relayed to opposite thalamus and some hypothalamic nuclei. Located in jugular foramenXVagus nerveBoth Sensory and MotorPosterolateral sulcus of MedullaNucleus ambiguus, Dorsal motor vagal nucleus, Solitary nucleusSupplies branchiomotor innervation to most laryngeal and all pharyngeal muscles (except the stylopharyngeus, which is innervated by the glossopharyngeal); provides parasympathetic fibers to nearly all thoracic and abdominal viscera down to the splenic flexure; and receives the special sense of taste from the epiglottis. A major function: controls muscles for voice and resonance and the soft palate. Symptoms of damage: dysphagia (swallowing problems), velopharyngeal insufficiency.

There are 12 cranial nerves, they are as followed;
(I) Olfactory
(II) Optic
(III) Oculomotor
(IV) Trochlear
(V) Trigeminal
(VI) Abducens
(VII) Facial
(VIII) Vestibulocochlear
(IX) Glossopharyngeal
(X) Vagus
(XI) Accessory
(XII) Hypoglossal
CN I - Olfactory, CN II- Optic, CN III- Oculomotor, CN IV- Trochlear, CN V- Trigeminal, CN VI- Abducens, CN VII- Facial, CN VIII- Vestibulocochlear, CN IX- Glossopharyneal, CN X- Vagus, CN XI- Accessory for vagus, CN XII- Hypoglossal, twelve cranial nerves. Functions: Olfactory I (smell) a sensory motor, Optic II ( vision) a sensory motor, Oculomotor III (eye movement) a motor, Trochlear IV (eye movement "polley" rotation of eye) a motor, Trigeminal V (mastication " chewing", nasal, propriaception of the tongue) mixed, Abducens VI (eye movement, control the lateral rectus muscle)a motor, Facial VII (controls facial muscles, taste receptors) mixed, Vestibulocochlear VIII (hearing, balance) special sensory, Glossopharyneal IX (taste, swallowing) mixed, Vagus X (taste, swallowing, connected to ear, largest cranial nerve), Accessory for vagus XI (talking, swallowing, shrugging) a motor, Hypoglossal XII (tongue movement). Here you have the twelve cranial nerves and their functions.

Because somebody would ask why it wasn't cranial nerves instead of brainial nerves.
The nerves involved in diplopia include three cranial nerves: the oculomotor nerve (third cranial nerve), the abducens nerve (sixth cranial nerve), and the trochlear nerve (fourth cranial nerve).
Dorsal and ventral roots are a feature of spinal nerves only. Cranial nerves do not have dorsal and ventral roots.
Cranial nerve 4 (IV) is the trochlear nerve.

How many cranial nerves are there
Rats have twelve pairs of cranial nerves.
There are 12 pairs of cranial nerves that are part of the PNS. These nerves are sensory, mixed and mostly motor.
The number of cranial nerves that a cat have is 12. The cranial nerves are mostly located at the cats brain.
nerves emerging from brain are called cranial nerves.they are 12 pairs
Cranial Nerves 1-2 Cranial Nerves 3-4 belong to the midbrain. Cranial Nerves 5-8 belong to the pons. Cranial Nerves 9-12 belong to the hindbrain.
Because somebody would ask why it wasn't cranial nerves instead of brainial nerves.
12
yes! there are 12 pairs of cranial nerves
The cranial nerves exit from the brain inside the cranial cavity.
