How fast do you think you are? Do you know what a reflex and a reaction are? This lesson plan tells all about the quickness of your nervous system and the muscular system, which the nervous system innervates.
The frontal lobe is generally where higher executive functions including emotional regulation, planning, reasoning and problem solving occur. This is why in frontotemporal dementia, personality changes are often the first signs of the disease
The nervous system is a remarkable network of nerves and cells that orchestrates and regulates all bodily functions.

Guiding questions for each lecture
You can use these questions to review your lectures and check if you caught everything/understood everything discussed in lecture or your pre-class material.
Lecture 1 guiding questions
At a high level (big picture), can you answer the following?
What makes up the nervous system? (what cells)?
What are the two major anatomical divisions of the nervous system?
What are the divisions of the peripheral nervous system?
How do neurons communicate?
Lecture 2 guiding questions
Describe several ways that intracellular fluid (ICF) differs from extracellular fluid (ECF). What ions are higher in the ICF vs ECF?
Describe what a concentration gradient is and how it leads to diffusion and the establishment of a dynamic equilibrium.
Can you identify the flow of ions in/out of cells based on concentration gradients?
Describe the mechanism of the Na+/K+ pump and explain how it contributes to the resting membrane potential of a cell.
What would happen to the resting membrane potential if the Na+/K+ pump was mutated and not working?
Describe the mechanism of Na+ and K+ leak channels. How do they contribute to the resting membrane potential of a cell? How do they contribute to membrane permeability?
What is the resting membrane potential? What voltage value is it typically for most cells in your body?
