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

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.

Action potential and voltage-gated ion channels
Depolarized voltage that is
