Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the key biological processes?Embryogenesis, tissue patterning, cell differentiation, wound healing, and cancer suppression
2. What is the signaling modalities?Endogenous electric currents and fields, transmembrane potential differences, and ion fluxes
3. What are developmental bioelectric signals?They are tiny electrical currents made by ions moving across cell membranes that help cells grow, move, and form tissues.
4. How do ions create electrical signals in our bodies?Ions like sodium, potassium, calcium, and chloride move through special channels and pumps, making tiny currents and voltage differences across cell walls.

Transmembrane Potential: The electrical potential difference across a cell membrane, crucial for cellular signaling.
Morphogenesis: The biological process that causes an organism to develop its shape.
Ion Channels: Pore-forming proteins that allow ions to pass through cell membranes, controlling electrical flow.
