Sphenomandibularis

From Wikipedia, the free encyclopedia

The Sphenomandibularis is a muscle attaching to the sphenoid bone and the mandible.[1][2] It is a muscle of mastication.[3]

Unlike most of the muscles of the human body, which had been categorized several centuries ago, Sphenomandibularis was discovered in the mid-1990s at the University of Maryland at Baltimore.[4][5] The findings were published in 1996.

Sphenomandibularis is considered by many sources to be a portion of the temporalis, rather than a distinct muscle.[4][6][7]
