Thanks for the reply, Glider. That makes sense. I was misinterpreting the question.

Yes, the P wave corresponds to atrial depolarization. Additionally, the so-called "QRS complex" is mainly ventricular depolarization (along with atrial repolarization, which is masked). The T wave represents ventricular repolarization.

I remember learning this very topic in a wellness class in high school. According to my teacher then, the answer was that fat throughout your body is broken down. In other words, you cannot target a specific part of your body for fat loss by exercising that region specifically. Keep in mind that I learned this in a wellness (health) class, not really a science class, so I can't vouch for the validity of the info.

Hi, everyone. The following question was on an exam that I took recently in an undergraduate physiology course: How is it that if all sensory information is encoded in the form of action potentials, we can differentiate between sensory stimuli? My answer, which was marked incorrect was... "The number and frequency of action potentials is different for different stimuli." The answer written on the exam key was... "Anatomical connections." (nothing more... that's it) After reviewing physiology-related websites (including those for other physiology courses), I think my answer is correct, and I'm not sure what my professor's answer even means. Anyone have any insight?
