The olfactory nerves pass through the cribriform plate of the ethmoid bone. This structure contains multiple small foramina that allow the olfactory nerve fibers, which originate from the olfactory bulb, to reach the nasal cavity. These nerves are responsible for transmitting sensory information related to smell from the nasal epithelium to the brain.

What cranial nerve passes through the foramen magnum?
olfactroy olfactroyOlfactory nerves Olfactory nerves
What is the function of the cribirform plate?
The cribiform plate is a bony structure in the skull that contains small holes through which olfactory nerve fibers pass to connect the nose to the brain. Its main function is to allow for the sense of smell by transmitting olfactory signals to the brain.
What bones house the canal in which olfactory neurons pass to reach the nasal cavity?
The olfactory neurons pass through the cribriform plate of the ethmoid bone to reach the nasal cavity. This plate contains numerous small foramina that allow the olfactory nerve fibers to extend from the olfactory bulbs to the nasal epithelium. The ethmoid bone is located between the eyes and forms part of the nasal cavity and the base of the skull.
Why are cranial nerves known as cranial neveres not branial nerves?
Cranial nerves are named as such because they arise directly from the brain (cranium) rather than from the spinal cord. The term "cranial" is used to refer to structures within or connected to the skull, while "branial" is not a recognized term in anatomy.
Do horns have nerves?
Yes, horns do contain nerves. In animals like cattle and goats, the horn is made of keratin and grows from a bony core that is connected to the skull. This bony core is rich in blood vessels and nerves, which provide sensation and help in the growth and maintenance of the horn. Therefore, horns are sensitive structures that can experience pain and discomfort if injured.
Which nerves go through openings in the skull and stimulate the head and neck?
cranial nerves.

What is a large mass of nerves located in the skull?
The brain is a large mass composed of nerves that rests in the skull.
Where is the cruciform plate?
The cruciform plate is a bony anatomy located in the neck area of certain animals, such as horses and cattle. It is located at the base of the skull where the neck attaches, providing structural support and attachment points for neck muscles.
What nerves exit from skull through jugular foramen?
The glossopharyngeal (CN IX) and Vagus (X) exit the skull through the jugular foramen.
What protects the nerves of the brain?
the skull
What is the function of the cribriform plate?
The cribriform plate is a thin, bony structure located in the skull that forms part of the ethmoid bone. Its primary function is to support the olfactory bulb and allow for the passage of olfactory nerves, which are responsible for the sense of smell. The numerous small holes in the cribriform plate enable these nerves to extend from the nasal cavity to the brain, facilitating the transmission of scent information. Additionally, it plays a role in separating the nasal cavity from the cranial cavity.

The olfactory nerve tracts could be most easily damaged by a fracture of the bone?
The olfactory nerve tracts, responsible for the sense of smell, could be most easily damaged by a fracture of the cribriform plate of the ethmoid bone. This bone is located at the base of the skull and has small perforations for the olfactory nerve fibers to pass through, making it vulnerable to damage from trauma.
