Understanding physiological buffer systems is essential for both DAT Biology and General Chemistry. The bicarbonate buffer system is the primary extracellular buffer and accounts for most of the buffering capacity in plasma. DAT Destroyer: DAT Destroyer 2026 — Complete DAT Science Prep System...

Hi! Currently wrapping up my first year of college and looking for advice on course selection for sophomore year--I need to take biochemistry next year but must do so in the spring (need 1 semester of ochem before biochem, which I will be taking in the fall. So the earliest possible time for my...

DAT Question of the Day Alcohol consumption affects multiple neurotransmitter systems. After several drinks, which of the following will be decreased? a) GABA b) Serotonin c) Glutamate d) Dopamine e) Endorphins f) None — all increase Correct Answer: C) Glutamate Alcohol increases...

Hi there! I've recently decided to in-depth study ECG and fo in some real big trouble. I've heard from a cardiologist that "r" wave in V1 records right ventricle depolarization (as it is closer to RV), while "s" wave records LV depolarization. And, at the same time, in the frontal plane, q-r-s...

Hey! I am a current UC first year medical student and alumni of the Cincinnati SMP. I didn't see a thread started for the next cycle so I thought I'd start one. Let us know if you have any questions about the program!

I was wondering why vision loss occur peripherally first in glaucoma. Is there an anatomical/structural reason for why peripheral vision is affected earlier by high intra-ocular pressure?

In myogenic mechanism when a transmural pressure increase blood vessel constrict to regulate the flow In stress relaxation when pressure increases blood vessels dilate to accommodate extra blood. So what happens to vessel radius when pressure increases?

I was recently accepted into the MS physiology program at Tulane, however I can't find any information from alumni online. I was wondering if any alumni or friends of alumni could speak to what the program is like, how to succeed in the program, and how it compares to the MS program of anatomy...

Hi, We are the development team of a just-released, medically-accurate software application with 3D, living, breathing organs that you can explore, dissect and in some cases, even fly through. We would like you to try our free demo version that is a sneak peek at the full version of Sharecare...

I completed my Freshman year with all A's in my Biology courses: Intro to Biology, Anatomy & Physiology 1/2 and Microbiology so I'm thinking about skipping the introduction classes to Chem and Physics and jump right in to Gen Chem and Phys 1 Sophomore year (this fall).

Hi guys, I noticed there's no thread for this yet. I was accepted 5/3 and I was wondering if any alumni had any input on this program/ its helpfulness for med school. I am also considering GT SMP and would like to hear some of the differences of these two programs besides the technical...

I am an undergrad student who doesn't need to take animal physiology to graduate. However its a required course for some vet schools. Does anyone know if you can be enrolled at two universities (one of them online). I'm not sure if I need this course to transfer to my current school to...

Hi all, I'm not sure if other med students experience this, but when we are lectured on a disease, the doctors often list the signs and symptoms without really explaining why we see them or what happens in the body that leads to them; They almost never explain the physiology behind them (for...

Suprised there doesn't seem to be a thread for this SMP yet, so I thought I'd start one. Anyone else applied and waiting to hear back?

I have a sort of stupid question. I had this pretty simple question on an exam and it has been bothering me ever since. True or False: Myelination increases the speed of an action potential. Now, if the question stated, “Myelination increases the conduction speed of an action potential”, I...

For those of you have taken the new MCAT and done well on the B/B section, is it helpful to have taken an upper level physiology course? Is that level of detail helpful or does the B/B section test physiology at a lower level detail (but more conceptually) such as what you might find in a two...

I’m a first year student.

Hey all! I currently live in Hawaii and am heavily interested in applying to the Army-Baylor DPT program. This program requires that all labs be taken in-person. I work full time and I'm three pre-requisites behind (Anatomy, Physiology, and Biology). I have scoured the interwebs and cannot...

Hey guys! I apologize beforehand if this is a common topic, I've searched the forums and could not find any thread. I'm a second semester medical student currently undergoing the GI system. I've been using Constanzo for physio with a bit of Guyton here and there but mostly Constanzo but I've...

I was wondering if anyone can offer some advice for Physiology NBME shelf. I heard from multiple people that the exam is a brutal guessing game. What is the best source of questions to practice from that is similar to the shelf exam? Should I focus more on diagrams? Would you guys recommend...

I got accepted to both of them for Fall 2018. I needed help deciding which one is better to got to. Which one has better chances of getting me into a dental school (asap)? Given, I perform the same and get at least a 3.5+ GPA in both. I have read some forms discussing Rutgers masters but there...

I'm taking human anatomy & physiology in my undergrad but in my current shadowing position at a veterinary surgical clinic I feel I would appreciate surgical procedures better if I had a more thorough understanding of, in my case, canine and feline anatomy and some basic physiology. I have been...

I'm a non-Canadian international student looking to strengthen my science GPA before applying to US med schools. I plan to apply after completing a Master's program. I have 3.51 uGPA, 3.46 sGPA from a top ten university in the US (notorious for grade deflation), and 501 MCAT (retaking). I felt...

I am taking the mcat in spring 2019 and I am trying to decide which courses will courses to take at my school to help me get a better score. I will be taking Biochemistry in the fall and I am trying to decide between taking 1 of the following 3: genetics, cell bio, or physiology. The remaining...

Hi everyone, I'm planning to take the OAT in the spring or summer of next year and was wondering, how much anatomy and/or physiology is on the OAT? Human Physiology is one of the hardest biology courses at my school, so I was wondering if it's worth it to try and take that class or if I will be...

I am looking at my school's PT pre-reqs, and for the A&P sequence, there is an option to take either: Human Anatomy (4 credits), then Human Physiology with lab (3+1), and also a separate anatomy lab (1). OR Anatomy & Physiology I + lab (3+1), then Anatomy & Physiology II + lab (3+1). I imagine...

Hey all, I'm new on here but think this would be a great resource for info/feedback! I need recommendations on where to take an ONLINE Physio I/II course (not A&P)! Friends and I need to take it over the summer, but it's okay if it crosses over spring/fall semester. ANY HELP IS APPRECIATED. My...

There seems to be nothing about this program on SDN. I would love to hear from others who are in the current class or have graduated from this program. Here is a link to their program: MCW: Master's in Medical Physiology | Physiology

So in my Human Physiology textbook it says, interneurons are important in integrating peripheral responses to peripheral information Could someone please explain this phrase to me?:)

I am dual AA/diploma recipient currently attending the University of Florida as a freshman and currently have 15 credits. My academic adviser has a huge issue with my course load: Organic I, Physics (W/O calc) with lab I, Human Physiology, Economics food issues, and and introductory course to...

In my book, it says, Adrenaline has less effect [I think they're comparing it to noradrenaline] on ABP due to vasoconstriction and vasodilatation of skeletal muscle arterioles and so TPR is slightly affected. It affects SBP while DBP is slightly decreased. Pulse pressure is augmented but MAP...

Why does it say that in diastolic dysfunction the pressure-volume loop shifts to the right, decreasing SV. But in Systolic dysfunction, pressure-volume loop shifts upwards and to the left, decreasing SV? :lame:

I know what a stimulus is, but what's a stimulus artifact?

In my book it says, Heterometric regulation: It's characterized by: It depends on a different EDV (increased ventricular blood volume at end of diastole, increases CO and vise versa) Could someone please explain this sentence.:(

In my book it says, increased venous tone increases venous return, but what does venous tone mean?:)
