The vestibular (VIII)
When taste buds are stimulated they can produce 4 different sensations (sweet, salty, bitter, sour). These nervous impulses are carried to the brain by the facial nerve (cranial nerve VII)from the anterior 2/3 of the tongue and by the glossopharyngeal (cranial nerve IX) from the posterior 1/3 of the tongue.
the olfactory (smell) and gustatory (taste) sensations pass along the cranial nerves directly to the brain. smell signals travel from the olfactory nerve (made up of groups of nerve fibres ) to a patch of the cortex located in the temporal lobe.

olfactory
Much of what most people consider "taste" actually is smell. Most fruit really tastes pretty similar... if you plug up your nose so you can't smell it, the difference between two fruits of similar acidity and sweetness is mainly in the texture. So, in that sense, yes. There is no direct causal relationship on a physical level because taste and smell are mediated by different types of receptors detecting different types of chemical compounds. Smell is carried from olfactory receptors in the nose to the brain via the Olfactory Nerve (cranial nerve I). Taste is carried from gustatory receptors on the tongue to the brain via the Facial Nerve and the Glossopharyngeal Nerve (cranial nerves VII and IX). However, these signals are integrated extensively in the cerebrum and many connections are made. Therefore, it is plausible that the mere smell of a certain type of food can elicit the memory of the taste of that particular food.
Brances of the Facial (VII), Glossopharyngeal (IX), and Vagus (X) cranial nerves carry information about taste
vestibular (VIII)
This nerve is one of the 12 cranial nerves. It is for the sense of taste. This sense is important because many poisons are bitter.

Optic Nerve = Vision Oculomotor Nerve = Eye movement; pupil constriction Trochlear Nerve = Eye movement Trigeminal Nerve = Somatosensory information (touch, pain) from the face and head; muscles for chewing. Abducens Nerve = Eye Movement Vestibulocochlear Nerve = Hearing; balance Vagus Nerve = Sensory, motor and autonomic functions of viscera (glands, digestion, heart rate) Spinal Accessory Nerve = Controls muscles used in head movement. Hypoglossal Nerve = Controls muscles of tongue
