PIRA 5B40.10 - Neuron Model
Photo Shows Apparatus used by the University of Texas at Austin.
Instructions / Notes:
- This is a model of a neuron and an axon with specific parts labeled.
- Labelled key included with demo.
Concepts Conveyed:
- A non-signaling neuron maintains a stable voltage across its membrane called the resting
potential. This resting potential is determined by the concentration gradient of ions across
the membrane, with the most abundant being Na+/K+ and Cl-.
- The electrical potential difference between the inside and outside of the cell is called the
membrane potential, with the inside being more negative than the outside.
- Neurons generate electrical signals through controlled changes in the permeability of
their cell membrane to particular ions.
