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."

"I'm Acting Atypical of Myself"

Explanation

In the sarcormere, the I band consists of actin and the A band consists of myosin. The "Atypical" part also explains that usually when something contracts it moves, but the A band remains unchanged, so this is not typical!!

Mnemonic device

"Ready, Coupling, Bending, and Letting go"

Explanation

Crossbridge Cycle:
The most basic part of the functional muscle is the cross bridge site where muscular contractions occur.
The process of myosin heads attaching to actin, bending, then releasing takes four steps: Ready, Coupling, Bending, and Letting go.
A different chemical triggers each step thusly:
Hydrolysis makes Ready;
Calcium ions cause the Coupling;
ADP bends the myosin head;
ATP lets go.
