Cranial Nerve I - Olfactory Nerve | Origin, Structure, Function, and Testing

The video tutorial explains the olfactory nerve, a sensory cranial nerve not associated with the brainstem. It covers the anatomy of the olfactory system, including the olfactory bulb, cribriform plate, and receptor cells. The process of odorant detection and transmission to the brain is detailed, highlighting the role of mitral cells and olfactory pathways. The video also discusses testing methods for olfactory nerve function, including identifying normal smell, hyposmia, and anosmia, and emphasizes cultural sensitivity in test odor selection.

What is the significance of the orbital frontal cortex in relation to smell?

How does the hippocampus contribute to the perception of smells?

Describe the testing procedure for assessing the function of the olfactory nerve.

What are the potential causes of hyposmia and anosmia?
