Innervation of the tongue, palate, pharynx & larynx with mnemonic

Hey everyone!
We are learning innervation of some muscles today! Yaay!

Glossal means pertaining to or near the tongue.. That's your starting point.

All muscles ending in "glossus" are supplied by hypoglossus
..Except palatoglossus.

Why? Because palate!

All musles of the palate are supplied by the vagus
..Except tensor veli palatani.

Why? Because it's a tensor!
All muscles in the head beginning with "tensor" are supplied by V3.

Pharynx and larynx is easy too.. All you need is a mnemonic!

Bernard Soulier syndrome mnemonic

Competitive and non competitive inhibitors simplified

Let me present to you the most understandable, simplified, awesome analogy for explaining competitive and non competitive inhibitors =D

Ferrous vs Ferric mnemonic

Ferrous vs ferric

Aortic arch derivatives mnemonic images

I made these diagrams guessing they'll be helpful ^__^

Aortic arch derivatives

The greater part of the first and second artery disappear. In adult life first arch artery is represented by the maxillary artery and the second arch persists for some part of fetal life as the stapedial artery.
The mnemonic people use for that is, "First is max" & "Second is Stapedial" =)

Competitive vs Non-Competitive Inhibitors mnemonic

Competitive vs Non-Competitive Inhibitors mnemonic graph

Kompetitive Inhibition: Km Increases; no change in Vmax.

Non-kompetitive inhibition: No Km change, but Vmax decreases.

Usually, on the Lineweaver-Burk Plot, Vmax will represent the Efficacy of a drug on the Y axis & Km will represent the Potency on the X axis.

Mnemonic: "Very efficient & competent"

Of course, that Lineweaver-Burk guy was very efficient & competent! 

The place where I live, there is a tailor's shop named competitive scissors. That's how I remember that competitive inhibitors cross the vectors at the Y axis in Lineweaver-Burk Plot.

Another way to remember this is, competitive inhibitors cross each other competitively, whereas noncompetitive inhibitors do not.

Another mnemonic to remember the shift to left or right in the simple graph is explained in the Oxygen hemoglobin dissociation curve mnemonic.

Hope it helps ^_^

Difference between ribose and deoxyribose sugar menmonic

Difference between ribose and deoxyribose sugar menmonic

In ribose, carbon atom 2 (C2) carries one hydroxyl group.

In deoxyribose, carbon atom 2 (C2) carries a hydrogen atom instead of a hydroxyl group.

Mnemonic:
"Conversion of RNA 2 DNA involves C2"
"Conversion of RNA to DNA involves the second carbon atom"

Nucleoside vs Nucleotide

Nucleoside vs Nucleotide

Nucleoside and Nucleotide mnemonic:
nucleoSide has Sugar and baSe.
nucleoTide has phosphaTe.

Amino acids necessary for purine synthesis mnemonic

Amino acids necessary for purine synthesis menmonic

Amino acids necessary for purine synthesis menmonic:
"GAG"
Glycine. Aspartate. Glutamine.

The image helps me remember "Purines" & "Gag" together.

"PURr GAGa"

Purine and pyrimidine nucleotides mnemonic

Mnemonic for purine nucleotides:

"Pure as gold"

"PURe as AG"

Purine nucleotides are Adenine and Guanine.

"Goooold"

Mnemonic for pyrimidine nucleotides:

"Cut the pie"

"CUT the PY"

Pyrimidine nucleotides are Cytosine, Uracil and Thymine.

"3.14159265..."










How to remember that it is pyrimidine - pyrimidine dimers and not purine - purine dimers that are formed on exposure to UV light: Pyrimidine is the bigger word. People who have big hearts fall in love with each other.

Mnemonic for base pairing of nucleotides

DNA base pairs menemonic

Mnemonic for base pairing of nucleotides:

"GCAT"

G ≡ C, A = T.

Guanine forms three hydrogen bonds with cytosine.

Adenine forms two hydrogen bonds thymine.

"Gee.. CAT!"

Amino acids with electrically charged side chains mnemonic

Mnemonic for positively charged basic amino acids:

"He is liar"

"Heis LyAr"

Histidine. Lysine. Arginine.

"He is basically a liar, he is positively a liar, LyAr Heis."

Say that to yourself a few times and you've got em memorized! =P

Mnemonic for negatively charged amino acids:

"GA"

Glutamate. Aspartate.

Glutamic acid. Aspartic acid. Acidic amino acids.

Question asked on tumblr:
Basicity: the willingness to donate electrons
Wait, why would they be positive again? Aaaaahhhh

Answer:
Hey don’t get confused between your “basic” concepts! *pun intended*

I was talking about being positive in the physiological pKa.

All amino acids can act as either an acid or a base because they have a carboxyl group than can lose protons and an amino group than can gain protons/donate electrons.

Amino acids that are said to be basic have an extra moiety which will accept electrons (Their side chains contain nitrogen and resemble ammonia, which is a base at neutral pH).

They will have iso electric points at a pH higher than physiological pH and will be positively charged at physiological pH (You need a more alkaline environment to obtain an overall neutral charge because the amino group can hold onto another proton).

In other words, their pKa’s are high enough that they tend to bind protons, gaining a positive charge in the process.


Similarly, amino acids that are said to be acidic have an extra carboxyl group. They will have iso electric points at a pH lower than physiological pH and be negatively charged at physiological pH (You need a more acidic environment to obtain an overall neutral charge because the carboxyl groups can more easily lose a proton).

Multiple Endocrine Neoplasia mnemonic

Hey everyone!

I modified the mnemonic I had for the MEN syndromes to make them work for me =)
Here it goes -

Mnemonic for MEN I: "I pee."
For MEN I, remember the P's.
Pituitary, Parathyroid, Pancreas.

One sounds like, "Won", reminding us that MEN I is also known as Wermer's syndrome.

Mnemonic for MEN IIA: "I am meant to sit in an AC room."
For MEN IIA, remember the C's.
Calcitonin, Calcium, Catecholamines.

I think of "2 ASS" to memorize MEN 2A is also known as Sipple Syndrome.

Mnemonic for MEN IIB:
"Every man wants to be a Pharaoh with a Medium Car on Mars with the New Romans."
Pheocytochroma, Medullary carcinoma, Marfan's syndrome, Neuromas.

I made an illustration for this too xD
