What This Document Is
This document is a review guide for the second exam in Colorado State University’s Principles of Human Physiology (BMS 300) course. It focuses specifically on the nervous system, covering key concepts needed for exam preparation. It’s designed to help students consolidate their understanding of the material, not to replace lectures or the textbook.
Why This Document Matters
This review is essential for BMS 300 students preparing for their second exam. It’s most useful *after* attending lectures, completing readings, and working through assignments. The guide serves as a focused checkpoint to identify areas needing further study. It’s intended to be used in the days leading up to the exam as a final review tool.
Common Limitations or Challenges
This review guide provides a condensed overview and does *not* contain the full depth of information presented in the course. It won’t teach you the material if you haven’t already engaged with it. It also doesn’t include practice questions or detailed explanations of complex processes – those are found in other course materials. This is a focused review, not a comprehensive textbook replacement.
What This Document Provides
This review guide includes information on:
* **Cellular Organization of the Nervous System:** Input, trigger, and conductile regions of neurons, and their functions.
* **Axoplasmic Transport:** Anterograde and retrograde transport mechanisms, including the roles of kinesin and dynein, and the differences between slow and fast transport.
* **Resting Membrane Potential:** The factors contributing to the resting membrane potential, including ion concentrations and the Nernst equation.
* **Ion Concentrations:** Key intracellular and extracellular ion concentrations (K+, Na+, Ca2+, Cl-).
* **Ion Channels:** Descriptions of various ion channels (K leak, voltage-gated K, voltage-gated Na, voltage-gated Ca, ligand-gated ionotropic) and their roles.
* **Active vs. Passive Membrane Transport:** A brief distinction between the two.
This preview *does not* include detailed explanations of action potentials, synaptic transmission, or specific neurological disorders. It also does not contain any diagrams or practice problems.
