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.

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.
· See diagram.
· Note vallate is also sometimes called circumvallate.

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.
