8. Find and for the parametric curve defined by x(t) = t3 and y(t) = sin t. This is material from section 10.2.

A patient has damage to myelin in the central nervous system. Their neurons can still produce action potentials, but communication between brain regions is slower and less reliable. Explain which glial cell normally produces CNS myelin. Analyze why action potentials are slower when myelin is damaged. Explain how nodes of Ranvier are involved in normal fast conduction. Predict how damaged myelin could affect energy use by the neuron. Evaluate why symptoms may vary depending on which axons are affected.

A student writes: “If a red blood cell is placed in a hypertonic solution, water will move into the cell because the solution has more solute. The cell will swell.” Analyze the student’s statement. Identify what is correct, what is incorrect, and rewrite the explanation correctly.

Explain the role of ATP in action potential formation.
