Question

The odorant enters the ________________________ cavity and passes along the ________________________, which divides the nose into two nostrils, on its way past the ________________________, which make the air more turbulent. Then, it reaches the cilia on the receptors of the ________________________, where it binds, creating a neural signal. That signal travels through the ________________________ of the ethmoid, on its way to the ________________________. The signal is then transferred to the ________________________, which takes it to the olfactory area in the ________________________ of the cerebral cortex.

Answer 1

The process of olfaction begins when an odorant passes through the nasal cavity, binding to receptors in the olfactory epithelium, creating a neural signal that is sent to the olfactory bulb, and then to the temporal lobe of the cerebral cortex.

Step-by-step explanation:

The odorant enters the nasal cavity and passes along the septum, which divides the nose into two nostrils, on its way past the turbinates, which make the air more turbulent. Then, it reaches the cilia on the receptors of the olfactory epithelium, where it binds, creating a neural signal. That signal travels through the olfactory foramina of the ethmoid, on its way to the olfactory bulb. The signal is then transferred to the olfactory tract, which takes it to the olfactory area in the temporal lobe of the cerebral cortex.
