What nerve controls sense of smell?

Olfactory nerve
Olfactory nerve (CN I) The olfactory nerve is a solely sensory nerve and conveys the sense of smell. Its receptors are located in the olfactory mucosa under the roof of the nasal cavity.

What are the functions of olfactory bulb?

The olfactory bulbs receive information about smells from the nose and send it to the brain by way of the olfactory tracts.

What part of the brain is responsible for smell and taste?

The Olfactory Cortex is the portion of the cerebral cortex concerned with the sense of smell. It is part of the Cerebrum. It is a structurally distinct cortical region on the ventral surface of the forebrain, composed of several areas. It includes the piriform lobe and the hippocampal formation.

What is olfactory pathway?

The pathway of olfactory conduction begins with the olfactory receptors—small, slender nerve cells embedded in large numbers (about 100 million in the rabbit) in the epithelium of the mucous membrane lining the upper part of the nasal cavity. Each olfactory receptor cell emits two processes (projections).

What nerve controls taste?

The facial nerve (CN VII) innervates the anterior two thirds of the tongue, the glossopharyngeal nerve (CN IX) innervates the posterior one third of the tongue, and the vagal nerve (CN X) carries taste information from the back part of the mouth, including the upper third of the esophagus.

Which lobe is the olfactory bulb in?

Olfactory Output Connects Directly to the Cortex in the Temporal Lobe. Mitral cells and tufted cells send their process to the primary olfactory cortex, which is located on the inferior surface of the temporal lobe.

What nerve carries taste?

The three nerves associated with taste are the facial nerve (cranial nerve VII), which provides fibers to the anterior two-thirds of the tongue; the glossopharyngeal nerve (cranial nerve IX), which provides fibers to the posterior third of the tongue; and the vagus nerve (cranial nerve X), which provides fibers to the …
