Action Potentials
Details the action potential in neurons.
The resting potential of a neuron (-70mV) is maintained through differences in concentration and permeability of Na, K, and Cl ions.
A graded potential is created as neurotransmitters from adjacent cells that are either excitatory or inhibitory.
If the neuron reaches the threshold of -55mV an opening of voltage-gated sodium channels triggers an action potential that may affect other connected neurons.
Cell Cycle, Mitosis and Meiosis
How the cell cycle is used to create new cells.
The creation of identical diploid daughter cells, through mitosis, is described.
The creation of unique haploid daughter cells, through meiosis is also described.
The importance of cyclin and cyclin dependent kinases to regulate the cell cycle is included.
