what does allied health clinicians differ from others?

i've been reading a lot of terms regarding allied health clinicians and i dont know what it means.
i am still a nursing student and i really want to know this because it appears mostly in our clinical course.

thanks everyone.
allied health professions are clinical [color=#3300b5]health care professions distinct from [color=#3300b5]dentistry, [color=#3300b5]nursing and [color=#3300b5]medicine.[color=#3300b5][1] one estimate reported allied health professionals make up 60 percent of the total [color=#3300b5]health workforce.[color=#3300b5][2] they work in health care teams to make the [color=#3300b5]health care system function by providing a range of diagnostic, technical, therapeutic and direct [color=#3300b5]patient care and support services that are critical to the other health professionals they work with and the patients they serve.from wiki

Allied health are typically non-licensed or if licensed, not ultimately responsible for decisions in patient care.i.e.: paramedics work under a physician's license, PAs work under a physician's license, CNAs work under a nurse's license, RRTs are not responsible for making decisions in patient care. Hope this helps.
