Mnemonics

Greek: mnēmonikós - of, relating to memory

"A device, such as a verse or formula or rhyme, used as an aid in remembering concepts. Named for Mnemosyne, the goddess of memory in Greek mythology, mnemonics are also called memoria technica. The principle is to create in the mind an artificial structure that incorporate unfamiliar ideas or, especially, a series of dissociated ideas by themselves are difficult to remember. Ideally, the structure is designed so that its parts are mutually suggestive."

Mnemonic device

"C3a & C3b"

Explanation

Complement: function of C3a versus C3b
C3a: Activates Acute [inflammation].
C3b: Bonds Bacteria [to macrophages--easier digestion].

If wish to know more than just C3:
C3a, C4a, C5a activate acute.
C3b, C4b bind bacteria.


Mnemonic device

"Combined Complexes and Activators Alone"

Explanation

Complement cascade initiating items: alternative vs. classic
Classic: Combined Complexes. Complexes are made of Ab and Ag combined together.
Alternative: Activators Alone, or IgA. Examples of activators: endotoxin, microbial surface.


Mnemonic device

"N. MeninGitidiS and N. Gonorrhoea"

Explanation

Neisseria MeninGitidiS has M, G and S in spelling - hence ferments all three sugars - Maltose, Glucose and Sucrose, whereas
Neisseria Gonorrhoea has only G - ferments only Glucose.
