Senses the Neuron Tiffany Do

A neuron that is simulating signals.
A neuron synapses and signaling!

The main idea of Chapter 37 was that about neurons and how the synapses and signaling works. It's about how neurotransmitters pass info from vesicles from a cell to a synapse to another cell. Chapter 37 also includes info on the plasma membrane, flows of ions, and nerve impulse transmission.

"Each branched end of an axon transmits information to another cell at a junction called a synapse. The part of each axon branch that forms this specialized junction is the synaptic terminal. At most synapses, chemical messengers called neurotransmitters pass information from the transmitting neuron to the receiving cell." - Pg. 752 of the Campbell Biology In Focus

"The majority of synapses are chemical synapses, which involve the release of a chemical neurotransmitter by the presynaptic neuron. At each neurotransmitter and packages it in multiple membrane-enclosed compartments called synaptic vesicles." - Pg. 761

Graded Potential - The response to hyperpolarization or depolarization is simply a shift in the membrane potential.

Threshold - Action potentials occur whenever a depolarization increases the membrane voltage to a particular value.

Action Potential - A depolarization shifts the membrane potential sufficiently, the result is a massive change in membrane voltage.

Hyperpolarization - The increase in magnitude of membrane potential.

Depolarization - A reduction the magnitude of the membrane potential.
