3A: The very fact that you are able to understand this sentence means that neurons in your brain (85 billion in total) are talking to each other. Neurons are the living substance of the nervous system, which extends beyond the brain to the spinal cord and peripherally, allows you to think and process, make decisions, stand up straight, maintain your heart rate, rest and digest. You will come to appreciate the structure and function of the nervous system as we delve into its anatomy and physiology, from the gray and white matter to the cerebellum to the neurons.

What homeschoolers say about Khan Academy
Homeschoolers widely appreciate Khan Academy for its extensive free resources covering a broad range of subjects and grade levels, including test prep and advanced topics. Many praise its clear video lessons and interactive exercises that allow self-paced learning. However, some families find the platform less structured and requiring significant parental oversight to ensure consistent progress. Additionally, while the content quality is generally high, a few users note that the presentation can feel dry or overly academic for younger learners. Overall, Khan Academy is valued for accessibility and depth but may need supplementation for a fully rounded homeschool curriculum.
