3. Describe the early stages of development in a mammalian embryo from the zygote to the gastrula. Follow the movement of cells and identify important regions and openings.
4. Explain how resting potentials are maintained and how action potentials are initiated and propagated in neurons.
5. Explain the sliding-filament model of muscle contraction.
