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."

"Nobody Likes My Educational Background"
"Never Let Monkeys Eat Bananas"
"Never Let My Engine Blow"
Explanation
Lymphocytes:
Neutrophils, Lymphocytes, Monocytes, Eosinophils, and Basophils.
These are the white blood cells also in descending percentage (65, 30, 6,
3, 1%).
To divide them by agranular and granular, put it as...
"Never Eat Bananas Like Monkeys"
Granulocytes - Neutrophils, Eosinophils, and Basophils.
Agranulocytes - Lymphocytes and Monocytes.
Mnemonic device

"Granpa BEN"
Explanation
Granulocytes:
Basophils, Eosinophils, and Neutrophils.
Agranulocytes:
Lymphocytes and Monocytes.

"Bad-o-phils and Easy-on-me-phils"
Explanation
Basophil vs. eosinophils: effect for allergic persons
Basophils are "Bad-o-phils" because they contribute to our allergic reactions.
Eosinophils are "Easy-on-me-phils" because they counteract our allergic reactions.
Mnemonic device
"Basophil has Big Blue Balls."
Explanation
Basophil morphology:
Basophil has granules.
Mnemonic device
"Master, His Hepes Causes Choking & Gaggin"
Explanation
Mast cell primary granule contents:
Mast - Mast cell
His - Histamine
He - Heparin
C - Chymase
Ch - Chemotactic factor for eosinophils

B-cell replies: "My Pleasure!"
Explanation
T and B cells: typesWhen bacteria enter body, T-cell says to B: "Help Me Catch Some!" B-cell replies: "My Pleasure!"
T-cell types:

Mnemonic device
"Bush Found The Pomp (not Bomb) , PLease Call Military Soldiers"
Explanation
The layers of the lymph nodes and their cellular content:
Bush Found - B cells in Follicle
The Pomp - T cells in Paracortex
PLease Call - Plasma cells in Cords of Medulla
Military Soldiers - Macrophages in Sinuses of Medulla
One more thing , this sequence is from OUTSIDE to INSIDE, i.e. the most outside layer is Follicle, and the most inside is Sinuses of Medulla.
The layer which is not developed in these diseases:
DiGeorge - Paracortex (no T cells)
Brutton`s Disease - Follicles (no B cells)
SCID - Follicles, Paracortex and Cords (no B cells, no T cells, and of course no PLasma cells).
Mnemonic device
"Th1nk BIG Mac Attack"
Explanation
Interferon gamma: action on macrophages
Th1 and NK cells Build Interferon Gamma.
Causes Macrophages to have an augmented Attack [by better lysosome function and increasing reactive oxygen metabolites, nitric oxide and defensins].
Mnemonic device
"Pay for Passive, Active Ages"
Explanation
Passive vs. active immunity
Passive: Pay for a shot of antibodies for fast results following exposure to Rabies, etc.
Active: Slow onset ("aging") and memory.
