Taste buds: vallate vs. fungiform distribution
- Cross sectional shape of the top of the bud tells their distribution.
- Vallate: has a shallow ‘V‘ at the top, so has a ‘V‘ distribution at the back of the tongue.
- Fungiform: top is round so it is towards the round end of the tongue.
- Note vallate is also sometimes called circumvallate.

L
Leukocytes: granulated and agranulated: “BEN Loves Money”:
Granulocytes:
- Basophil
- Eosinophil
- Neurophil
Agranulocytes:
- Lymphocytes
- Monocytes
- Alternatively: Granpa BEN…” to keep the granulated group straight.

- Mast cell primary granule contents“Master, His Hepes Causes Choking & Gagging!”:
- Mast = Mast cell
- His = Histamine
- He= Heparin
- C = Chymase
- Ch = Chemotactic factor for eosinophils
- Gag = GAGase

Muscle cells: cardiac vs. skeletal’s nuclei location/number
- Nuclei location mirrors where the muscle is located in human body.
- Heart muscle is in the middle of body, so heart muscle has nucleus in middle.
- Skeletal muscles are at periphery of body, so nuclei are at periphery.
- Also, you have 1 heart, so usually only 1 nucleus per heart muscle cell, but have many skeletal muscles,
- so have many nuclei per long fibre.

Muscle sarcomere: A vs. I as light or dark
- There is only one vowel in “dark” and one vowel in “light”.
- These one vowels match up to their one letter names:
- DArk band is the A
- LIght band is the I

Muscle sarcomere: H line vs. Z disc location
- HAZI (Hazy):
- H line is in A-band.
- Z disc is in the I

N
Neutrophil’s 2 distinctive physical features
1: There’s up to 5 lobes of the nucleus joined by thin appendages. Tie this to it being a
neutrophil nucleus by arranging the 5 lobes into a capital N for Neutrophil.
2: the chicken leg (Barr Body) sticking out. Say it out loud: chick-N. The chick-N leg is for
Neutrophil.
