BISC 411 Advanced Cell Biology
Cell line: Cells that have been modified so that they can grow and divide an infinite
number of times in culture.
Often these cells are derived from malignant tumors eg. HeLa cells, which were derived
in 1952 fro
Anatomy of the olfactory system
Olfactory sensory neurons project an axon to the olfactory bulb
Axons pass through the cribriform plate. Odorant inward current
Odorants are detected on sensory
cilia that project into the olfactory mucosa.

Introduction to Biomolecules
The food you eat, the silk a spider uses to make a web, the muscles in your body all of these
structures are made of macromolecules. Macromolecule is the term that biologists use for
