• Neuron structure (dendrite, axon, cell body, myelin sheath, axon terminal)
• The sequence of ion movements that constitutes an action potential
• Ion movement across the neuron membrane producing an action potential
• Electrical-to-chemical signal conversion at the synapse
• Correspondence between the sensor/control-center/effector labels and the specific textual description of each role
• Structural and functional differences between nervous and endocrine signaling
• Sensor-control center-effector structure of a negative feedback loop
• Fault localization within a novel negative feedback loop
• Metabolic (ATP) demand of nerve and muscle tissue
• The relationship between apparent output stability and active regulatory cost in a feedback system
• Classification of coordination responses as nervous vs. endocrine based on structural features

Every lesson is written for a parent with no teaching background: it opens with a short script to read aloud, names the specific wrong idea a student is likely to reach for and how to correct it, and closes with a practice sheet you may copy for your household. Scripture references are King James Version throughout. Black-and-white, 8.5 x 11 in. The whole year of this course is also in this store as a single book.
