Memorizing how to draw the nasal septum

Hey everyone!

Here's a mnemonic kinda video for how to draw the nasal septum --> http://www.youtube.com/watch?v=vY9dwSDNTLQ

I've always had problems remembering the names of various bones and cartilages so I made a silly mnemonic for myself.

Darrow-Yannet Diagrams simplified

What are Darrow Yannet diagrams?
They are graphs that tell you the osmolarity and volume changes of body fluids.

X axis represents volume.
Y axis represents solute concentration.

Total body water = 2/3 ICF (Intracellular fluid) + 1/3 ECF  (Extracellular fluid)

Remember:
All volume disturbances originate in the ECF compartment.
Changes in ICF are in response to changes in ECF.

How to make the graph in your head -
Step 1. Figure out what happens to the osmolarity and volume in the ECF compartment (ECF is the smaller compartment)
Step 2. Think how is ICF affected?

Let's review some examples to make sure we understand the concept!

What is the difference between prerenal failure & acute tubular necrosis?


What is prerenal failure?
Prerenal acute renal failure (ARF) occurs when a sudden reduction in blood flow to the kidney (renal hypoperfusion) causes a loss of kidney function.
In prerenal acute renal failure, there is nothing wrong with the kidney itself.

What is acute tubular necrosis?
Acute tubular necrosis is a kidney disorder involving damage to the tubule cells of the kidneys, which can lead to acute kidney failure.

What is the difference between prerenal failure & acute tubular necrosis?

Arteriovenous fistula - What happens to cardiac output and total peripheral resistance and why?

What is an AV fistula?
An arteriovenous fistula is an abnormal connection or passageway between an artery and a vein.

When an arteriovenous fistula is formed involving a major artery like the abdominal aorta, it can lead to a large decrease in peripheral resistance.

Why?

Difference between iron deficiency anemia and anemia of chronic disease

Hi everyone!
Sometimes simply reading doesn't help you get the difference..
So I made these notes to help you have a visual idea of the terms used while describing these diseases.

Medicowesome Flashcards 1 download

Hey everyone!
The first set of flashcards are ready for download B)

I sorted them out in different folders in case you wish to study them separately ^_^
Personally, I like mixing them all together and recollecting random facts as they show up.. Gets tougher =D

Oxygen - hemoglobin dissociation curve mnemonic

Hi everyone!
What is oxygen - haemoglobin dissociation curve or oxygen binding curve?
The oxygen - haemoglobin dissociation curve plots the proportion of haemoglobin in its saturated form on the vertical axis (fractional saturation of hemoglobin) against the prevailing oxygen tension on the horizontal axis.

What does it tell?
It tells you the affinity of hemoglobin for oxygen.

How does it do that?
It's simple!
If the curve shifts towards the right, hemoglobin has decreased affinity for oxygen.
If the curve shifts towards the left, hemoglobin has increased affinity for oxygen.

How do I remember the shift in curves?
Remember: Left shifted curve doesn't want to leave oxygen.

Obstructive and restrictive lung diseases

Happy friday everyone!
We’ll learn about obstructive and restrictive lung diseases today.
This is just a short summary for a quick review :)


Obstructive lung diseases - Characterized by airway obstruction.
You have an obstruction in air flow resulting in air trapping in the lungs.
Increased compliance: Due to the loss of alveolar and elastic tissue.
You have a problem getting air out of your lungs.
Mnemonic: Obstructive Out

They breathe like “poof poooooof”
In and oooooout
They take infinity to get it all out =P
So, FEV1 / FVC is decreased.

TLC and RV increased - Flow volume loop shifts towards left.

Examples: Any pathology that decreases the ability to develop a positive intrapleural pressure.
(Airways close prematurely at high lung volumes!)
Chronic bronchitis
Asthma
Bronchiectasis
Emphysema
COPD

Restrictive lung diseases - Characterized by restriction of lung expansion.
You have a problem getting air into your lungs.
Reduced compliance: Lungs become fibrotic, lose their distensibility and become stiffer.
Mnemonic: Restrictive Reduced compliance

They breathe like “poof pof”
In and out
They get everything out in one second =P
So, FEV1 / FVC is increased.

TLC and RV decreased - Flow volume loop shifts towards the right.

Examples: Any pathology that decreases the ability to develop a negative intrapleural pressure.
Pulmonary fibrosis
Asbestosis
Sarcoidosis
Pneumoconioses
Kyphoscoliosis
ARDS
Polio
Obesity

That's all!

I know you must've found the "poof" sounds pretty weird because that isn't the way you breathe
But they are a funny and they help me remember so I put it up anyway ^___^"
Just like "lup dubb" are official sounds for heart beats.. Which sounds would you assign to inspiration and expiration?
