Final answer:
The axons from the nerve cells in the nose are eventually routed to the olfactory bulb in the brain, which processes smell information. The olfactory tract connects to the olfactory bulb, and axons travel to various brain regions including the cerebrum and limbic system. These connections are responsible for the association of smells with memory and emotions.
Step-by-step explanation:
The axons from the nerve cells in the nose receive messages that are eventually routed to the olfactory bulb in the brain. The olfactory bulb is located on the ventral surface of the frontal lobe and is responsible for processing smell information.
The olfactory tract connects to the olfactory bulb, and from there, the axons split to travel to several brain regions. Some axons travel to the cerebrum, specifically to the primary olfactory cortex in the temporal lobe, while others project to structures within the limbic system and hypothalamus.
These connections allow smells to become associated with long-term memory and emotional responses, explaining why certain smells can trigger strong memories or emotions.
