Study Notes
Interference of Waves
- Constructive Interference: Occurs when two or more waves are in phase, resulting in their displacements adding up to produce a higher amplitude.
- Destructive Interference: Occurs when two or more waves are out of phase, resulting in their displacements negating each other to produce a lower amplitude.
Neuron Communication
- The presynaptic neuron is the neuron that transmits a signal to the synapse.
Synaptic Vesicles and Neurotransmitters
- Synaptic vesicles are tiny sacs that contain chemicals.
- These chemicals are released when the signal reaches the axon terminal.
- Neurotransmitters are chemicals found in synaptic vesicles that excite the postsynaptic neuron, muscle, or gland cell.
