action potential: A brief shift in electrical potential on the surface of cells, particularly nerve cells and muscle cells. It occurs when cells are stimulated, leading to the release of electrical impulses.
atom: The fundamental unit of chemical elements, consisting of a dense nucleus containing positively charged protons and uncharged neutrons orbited by negatively charged electrons.
average: The arithmetic mean of a group of numbers, calculated by dividing the sum of the numbers by the size of the group.
axon: The elongated tail-like extension of a neuron that carries electrical signals from the cell.
battery: A device that converts chemical energy into electrical energy.
calcium: A common chemical element in the earth’s crust, minerals, sea salts, bone minerals, and teeth, playing a role in the movement of substances into and out of cells.
cell: The smallest structural and functional unit of an organism, consisting of watery fluid surrounded by a membrane or wall.
cell membrane: The structure that separates the inside and outside of a cell, allowing some particles to pass through.
chemicals: Substances formed by the combination of two or more atoms in specific ratios and structures.
chemistry: The scientific field that studies the composition, structure, and properties of matter and their interactions.
concentration: A measure of how much one substance is dissolved in another substance.
contract: Initiates muscle activation by binding filaments within muscle cells, resulting in muscle contraction.
current: The flow of charge or electricity, typically caused by the movement of electrons.
develop: To appear or be produced naturally or through human intervention.
charge: The physical property responsible for electric force, which can be negative or positive.
current: The flow of charge or electricity, usually resulting from the movement of electrons.
Electrochemical gradient: Differences in the concentration of charged particles across a membrane, leading to an overall charge in an area.
electricity: The flow of charge, often resulting from the movement of electrons.
electrochemistry: The process by which electricity affects chemical changes in a substance, converting chemical energy to electrical energy and vice versa.
gradient: The degree of slope, inclination, or increase in some measure as we move along a scale.
ion: An atom or molecule that acquires a charge due to the loss or gain of electrons.
film: A barrier that blocks the passage of substances based on size or other characteristics.
migrate: Moving long distances in search of a new home.
logic: Tissue used for movement by contracting muscle fibers.
neuron: Cells of the nervous system responsible for transmitting information through electrical signals.
particle: A trace amount of something.
potassium: A reactive chemical element found in seawater and many minerals.
protein: A compound made of amino acids and essential for living organisms.
sodium: A metallic element found in common salt and sea salt.
stimulation: Something that triggers a reaction in a living organism.
taste: Sensing characteristic flavors using taste buds.
organization: Comprising cells, the substances that make up living organisms and their specific functions.
