Study Notes
Liquids and Solutions
- Condensation is the process of a gas changing to a liquid.
- Vaporization is the process of a liquid changing to a gas.
- A solute is the dissolved material in a solution.
- A strong electrolyte is very soluble and conductive.
- Pressure and gas solubility are directly proportional.
- A concentrated solution has a large amount of solute.
- Concentration is a measure of the amount of solute dissolved in a given amount of solution.
Osmotic Pressure
- Osmotic pressure gradients are created when solute molecules displace water, decreasing water concentration.
Miscellaneous
- 67%, 25%, and 8% are significant percentages in an unspecified context.
Electrophysiology of Nerve
- A neuron consists of supporting cells and neurons.
- Voltage-gated channels open and close in response to changes in the membrane potential.
- The potential difference in a resting neuron is the resting membrane potential.
- Action potentials are long-distance signals of axons.
Action Potential Phases
- Hyperpolarization: some K+ channels remain open, and Na+ channels reset.
- Repolarization: Na+ channels are inactivating, and K+ channels open.
- Resting state: all gated Na+ and K+ channels are closed.
- Depolarization: Na+ channels open.
- Hyperpolarization: increases in membrane potential, making it more negative.
- Repolarization: the inside membrane becomes less negative.
Elementary Phenomenon of Hearing
- The external ear receives sound waves.
