Human Body - Week 8 - Nose and Smell Receptors

Week 8: We made a model of the smell mechanism located in the top part of the nose.

Lots of tiny hair-like sensors reside in the upper nasal cavity. The smell receptors lie in a smell epithelium membrane along with mucus producing glands. The smell receptors pass through bone and connect to nerve cells which transfer smell information to the brain. The Way We Work by David Macaulay is full of detailed explanations of the human body.

We used some hearty foods to make a model of the smelling system:)

The tops of the broccoli were placed face down in the dish to represent the smell receptors.

They were covered in cheese, flour and milk to represent the smell epithelium.

Corkscrew noodles were placed into the mixture for the mucus producing glands.

It was covered with potato slices to represent the bone with holes to allow the connection to be made between the smell receptors and the nerves.

Spaghetti noodles were added to represent the nerves.

We baked the dish for 40 minutes at 375 degrees F and then ate it as part of our dinner. The kids giggled so much when they explained what we were eating to dad.
