The words that introduce adjective and adverb clauses are not those that introduce noun clauses.

The adjective clause structures the noun or pronoun and it is an independent clause. The adjective clause is introduced by words that begin with relative pronoun or subordinate conjunction, that is words like whom, what, whose, which and that.
Adverb clause structures the verb, adverb and adjective and also an independent clause. They are introduced by subordinate conjunction, words like after, although, it, as, before, etc,.
Noun clause can be anything. It can be indirect object or object of proposition or direct subject or subject. It is an independent clause and introduced with words like whomever, where, whoever, when, how,etc,.
