Brief psychotic disorder is when the duration of symptoms is less than one month.

If the symptoms have persisted for at least one month and last less than 6 months of onset, the diagnosis of schizophreniform disorder is made.

Glomerular filtration rate formula and mnemonic

Glomerular filtration rate formula

Submissions: Mnemonic for arterial involvement in atherosclerosis

The aorta is most commonly involved by atherosclerosis; followed by coronaries, popliteal arteries, carotids and circle of Willis.
Mnemonic: Aortic crocodiles popping from car of Willis.

This is high yield information, I remember an multiple choice question being asked in my Pathology exam on this. They particularly asked which part of the aorta is most commonly involved in atherosclerosis. So don't forget that it's the abdominal aorta!

Here is a nice image to go with the mnemonic to help you remember:

Cell mnemonics

Layers of the epidermis mnemonic:
"Cornea is lucid, granules are spiny"
Silly association to remember the sequence: Cornea is the outermost layer of the eye, and the base is always the innermost layer.
Cornified layer (stratum corneum)
Clear/translucent layer (stratum lucidum, only in palms and soles)
Granular layer (stratum granulosum)
Spinous layer (stratum spinosum)
Basal/germinal layer (stratum basale/germinativum)

Sarcomere with various bands mnemonic:
Z is the end  of the alphabet and Z is the end of the sarcomere.
M is the middle of the alphabet and M is in the middle of the sarcomere.
Attached to the M line are your Mighty Myosin (Mighty = thick filaments)
"My tits" (Sorry for the vulgar language) is for remembering that myosin is attached by titin to the Z line.
Actin (acthin) is the thin filament attached to the Z line.

H is a thick letter so only thick filaments are found in the H band.
I is a thin letter so I band has only thin filaments!

Myosin doesn't like to change and is very bossy. So it not only took the middle M letter for the M line, but also took the A alphabet to represent itself (How mean, poor Actin! T_T)
PS: A band represents the thick filaments irrespective of the overlap, unlike H band.
So during contraction, A band doesn't change (The myosin only part)
The H and I band changes in width during contraction.

Cell junctions mnemonic:

Mean systemic filling pressure

I never understood what it meant.

I found myself wondering.. What the heck is "The tightness with which the circulatory system is filled with blood." and what do you mean by "Pressure that exists in the vascular system if the cardiac output stops"?

Until one fine day I finally got it.

If you don't understand all those complicated (yet simple) terminologies and definitions.. You are just like me.. And I'm here to help you out =D
Here is how I understand it!

Imagine blood vessels are talking -
