What occurs first in an action potential?
What occurs first in an action potential? An action potential occurs when a neuron sends information down an axon, away from the cell body. Neuroscientists use other words, such as a “spike” or an “impulse” for the action potential. Action potentials are caused when different ions cross the neuron membrane. A stimulus first causes sodium […]
What is the symbol for concentration?
What is the symbol for concentration? Concentration is measured in various ways. The amount of substance dissolved per unit volume (symbol c) has units of mol dm –3 or mol l –1. It is now called `concentration’ (formerly molarity). The mass concentration (symbol ρ) is the mass of solute per unit volume of solvent. What […]
