Create mnemonics to remember terms
If you can make a connection to something you know, then you will remember the term better
Storytelling – create a story that links terms
Excite the brain – humor, shock, surprise
The brain remembers when information is attached to emotional experiences
![Page 38: Anatomy = structuresintichscience.weebly.com/uploads/2/2/4/7/22479874/... · Dorsal and Ventral In humans, terms are interchangeable with anterior and posterior In 4-legged animals,](https://reader033.fdocuments.net/reader033/viewer/2022060722/608295abb5a8fc5e3e2ab545/html5/thumbnails/38.jpg)
Use a variety of study aides – flashcards, quizlet, retype notes, highlight notes, ect
You’ll get bored easily if you use the same thing
Read aloud
Hearing the information and not just reading helps to remember terms better and engages the brain more

Repetition
Write words 30 times to commit the terms to long-term memory
Etymology – what does the term mean
Most anatomy terms have a latin or greek root
Study with friends and share the stories and
mnemonics you create
