You cannot use this sentence in your discussion board: “Dermatomes are useful to help localize neurologic levels, particularly in radiculopathy.” I have read this sentence about eleventy bajillion times without context or explanation. 1) It’s definitely plagiarism if you use this sentence. 2) This is a bad sentence full of jargon and no context. If you read the article and can explain what this sentence means in your own words, you have my full blessing.
