Homorganic consonants

Homorganic consonants (from homo- "same" and organ "(speech) organ") is a phonetics term for consonant sounds that are articulated in the same position or place of articulation in the mouth, such as [m], [p], [b] (pronounced with both lips), or [t], [d], [s], [z], [n], [l] (pronounced by touching the tip of the tongue to the upper gums). Consonants that are not articulated in the same place are called heterorganic.
