College question

Tess

So this is my first assignment for my medical terminology class, the professor wants us to write the definitions of some words she gave us. The only thing she said was to write the definitions in complete sentences. I emailed her asking if she wants us to write the definitions from the textbook or in our own words, she said either is fine but she prefers our own words. My question is how should I format this? Should I list it as 1. 2. 3.? I’m a bit confused.
