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.
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!
I had trouble remembering that Warthin's tumor is "Papillary cystadenoma lymphomatosum" and this happened.
Yes, feel the "Warth" (or maybe I'm just weird!)
Wrath of the Pa-cyst-ans? Warthin's tumor? Papillary-cystadenoma-lymphomatosum? YES!
I thought of writing the whole blog at once as I have a lot of mnemonics and tricks but I barely get time and it has been pending for a long time now so I thought of publishing it, hoping I'll keep updating this post as and when possible :)
"pH" for Parietal cells secrete H+ ions.
Parietal cells are also known as oxyntic cells.
"PC" for Pepsin is secreted by Chief cells.
(Chief cells are also known as peptic cells or zymogen cells.) Alternate mnemonic: I think of master chef making food rich in proteins, peptides being degraded by pepsin and that's how I remember the association that Chief cells secrete Pepsin.
G for G cells & G for Gastrin. (Hah! That was easy!)
S for S cells & S for Secretin! (Medicine is easy!)
A diagram to brush up your memory..
(And to remind you it's all simple & easy and that you've got this!!)
Cardiac Output and Venous Return curve simplified
I used to freak out when I first starting seeing this graph and related multiple choice questions in question banks. It's only in a matter of time that I realized these problems need only three variables to be figured out to choose the right answer!
The ventilatory drive of patients with chronic lung disease is primary due to their hypoxemia, rather than CO2 levels. This is because pCO2 receptors are adaptive. Chronically elevated pCO2 makes central receptors unresponsive in COPD patients. Administration of a high O2 mixture to relieve the hypoxemia is contraindicated because this removes the hypoxic drive, leading to severe hypoventilation.
Clinical scenario #2: Drug overdose where central receptors are blocked.
I thought of sharing something that inspired me.. It's about nutrition (Not my regular study post!)
In this age where cardiovascular problems and cancer have been on the rise like never before, it has become essential for us to eat healthy. We need to cut down on bad cholesterol and encourage fiber, nutrient rich, natural, unprocessed food.
Recently, there was a salad making competition held in my mom's school. Children of the second grade helped their mummy's make salads in the school.
For Human Developmental Index remember, "Humans LIKe development"
So it takes into consideration: Life expectancy, Income & Knowledge.
Physical Quality of Life Index, "LIL physical quality"
It takes into consideration: Life expectancy, Infant mortality, Literacy.
For remembering the I in both mnemonics, I think that development is linked to money (income). LIL should remind you of the little one, that is, the kid & hence infant mortality!
Hey guys!
These are some mnemonics I made on nutrition which is a part of my Preventive & Social Medicine (also known as Community Medicine).
We'll keep updating this section.
Please, please, please feel free to add your mnemonics as well ^__^
Deficiency of vitamin B1:
Thiamine deficiency causes Ber1 Ber1 (B1).
Deficiency of vitamin B2:
"A2 B2 C2"
A2 - 2 ATPs (FAD and FMN are derived from riboFlavin)
B2 - Vitamin B2
C2 - Cheilosis, Corneal vascularization Let’s call it ri-two-bo-flavin!
