Excitable Cells

Start with nerve cells

The flashcards on nerve cells and excitability offer a starting point. They ask what an excitable cell is and cover nerve cell structure, basic electricity, body fluid composition and ion types. Use the questions to check which terms you can explain before moving to the more detailed resources.

For a different angle, the sensory neuron flashcards ask about receptive fields, intensity coding, adaptation and receptor types. Answer in your own words, then return to any prompts you want to study again.

Connect movement and electricity

The mind map on diffusion describes movement down a concentration gradient and the approach to equilibrium. The map on ions introduces ion flow as a current, potential difference and resistance. Follow each map from its central idea through the connected points, then use the flashcards to practice recalling related terms.

For more circuit terminology, try the Cells as Circuits flashcards. They include prompts on current, charge, voltage and the phospholipid bilayer as a capacitor. Another flashcard deck covers batteries, resistors and capacitors alongside the Nernst equation.

Use the quiz after the maps

The quiz asks about graded potentials, action potentials and features of excitable tissue cells. After studying the maps and flashcards, try its questions and note any terms you want to revisit. You can move back to the ion map or the flashcards on membrane potential when you need another look.

Place the topic in the unit

Excitable Cells is a section of the Membrane Potentials, Action Potentials and Synaptic Transmission unit in Physiology. The resources on membrane potential and the quiz questions on action potentials offer ways to connect this topic with the unit. Choose a map or flashcard deck and use it alongside the quiz.
