The olfactory nerve (CN I) is the first and shortest cranial nerve. It is a special visceral afferent nerve, which transmits information relating to smell. Embryologicallly, the olfactory nerve is derived from the olfactory placode (a thickening of the ectoderm layer), which also give rise to the glial cells which support the nerve.

Each olfactory receptor cell emits two processes (projections). OLFACTORY PATHWAYS AND LIMBIC SYSTEM I. OLFACTORY PATHWAYS The sense of smell is much less essential than vision, audition or the somatic senses, and will therefore receive less emphasis in this course. However, since olfactory dysfunction can be an important diagnostic sign, it is important to have at least a rudimentary knowledge of the Olfactory receptor cells – bipolar neurons which consist of two processes: Dendritic process projects to the surface of the epithelium, where they project a number of short cilia, the olfactory hairs, into the mucous membrane. These cilia react to odors in the air and stimulate the olfactory cells. The olfactory nerve originates in the nasal mucosa on the upper part of the nasal cavity as special sensory cells (neurosensory cells of the mucosa), which are the first-order neurons in the olfactory pathway. The Olfactory Pathway The fibres of the olfactory nerves are processes of olfactory receptor cells lying in the epithelium lining the olfactory mucosa (Fig.

The oculomotor nerve is the third of 12 pairs of cranial nerves in the brain. This nerve is responsible for eyeball and eyelid movement. It follows the olfactory and optic nerves in terms of order.

The olfactory pathway handles smell. 1 Reception 2 Routes 3 Processing 4 Project to The receptors lie in the nasal cavity, on the olfactory epithelium. Each receptor cell has several receptors, and lies in the olfactory mucosa. Chemicals in the air dissolve in the mucosa. If the chemical affects the receptor, it sends an action potential.
