I have encountered students with Dyslexia having a really hard time passing an Anatomy and Physiology course since it requires learning all parts of the body and knowing how to spell them. What reasonable accommodations students with Dyslexia could receive in order to be successful?

I have encountered students that have disclosed their disabilities with admissions but refuse to provide documentation to receive the neccesary accomodations. What would be the best suggestion to encourage students to do so? Is it appropiate to push/ encourage students to do so?
