Olfactory nerve filaments are found
a. in the optic bulbs,
b. passing through the cribriform plate of the ethmoid bone,
c. in the optic tracts,
d. in the olfactory cortex.
Verified step by step guidance
1
Identify the function of the olfactory nerve, which is responsible for the sense of smell.
Understand the anatomical pathway of the olfactory nerve, which begins in the nasal cavity.
Recognize that the olfactory nerve filaments pass through the cribriform plate of the ethmoid bone to reach the olfactory bulb.
Eliminate options that do not align with the anatomical pathway of the olfactory nerve, such as those related to vision (optic bulbs and optic tracts).
Conclude that the correct location for the olfactory nerve filaments is where they pass through the cribriform plate of the ethmoid bone.

Olfactory Nerve Anatomy
The olfactory nerve, also known as cranial nerve I, is responsible for the sense of smell. It consists of sensory nerve fibers that originate in the olfactory epithelium and pass through the cribriform plate of the ethmoid bone to reach the olfactory bulbs. Understanding its anatomy is crucial for identifying its pathways and functions.
The cribriform plate is a bony structure located in the ethmoid bone of the skull. It contains numerous small holes through which the olfactory nerve filaments pass from the nasal cavity to the olfactory bulbs. This structure is essential for the transmission of olfactory signals and plays a key role in the sense of smell.
The olfactory bulbs are neural structures located at the base of the brain that receive input from the olfactory nerve. They process olfactory information before sending it to the olfactory cortex, which is responsible for the perception of smell. Understanding the relationship between these structures is vital for comprehending how olfactory information is processed in the brain.
