Depends a lot on the state, type of law and even the firm.
In Florida, there are paralegals and Registered Paralegals. The latter is a certification offered by the state Bar, which doesn’t mean a great deal but gets you a couple extra bucks per paycheck.
Most firms make a distinction between paralegals - staff who do pseudo-attorney work under the supervision of an attorney, but are not legally allowed to practice law independently - and legal assistants, who do stuff that attorneys’ time is better spent not doing (secretarial stuff, mostly - scheduling and taking dictation and the like).
There isn’t really a hard and fast rule, though; in smaller firms, the same person probably fulfils both capacities; in larger firms, there tend to be more associate attorneys to do the paralegal stuff.
There are also medical paralegals, who are generally qualified nurses and the like, who do medical record review and stuff like that, but I’ve never met one, for what it’s worth.
I’m a (small p) paralegal at a Florida insurance defense firm, within the workers’ compensation department. My duties tend to be comprised mostly of the record reviewing variety (medical records, financial statements and surveillance footage), although I also prepare form (ie. commonly used) motions, and sometimes write wholly original ones.
IME, a good rule of thumb is that paralegals have to know and understand some of the applicable laws, and legal assistants don’t (although legal assistants are likely to learn a ton about their fields just by listening).
