What is the difference between emphatic pronoun and reflexive pronoun?

An emphatic pronoun is an appositive to a noun or another pronoun and emphasizes the importance of the noun or the antecedent of the pronoun. A reflexive pronoun fills some function in the sentence, usually a direct or indirect object, different from that of the noun or pronoun pronoun to which it refers. Example as intensive: "I will feed the dog myself" or "I myself will feed the dog" connotes that the speaker or writer believes in his or her own importance, reliability, or special competence, while "Even with an injured arm, I can feed myself" does not. The latter is an example of a genuinely reflexive pronoun, in which the pronoun in question is the direct object of the verb in the sentence, not a mere appositive to the subject "I".
