mentalis muscle
A muscle of facial expression, innervated by the facial nerve, attached to the skin of the lower lip and inferior to the lower lip (in humans this region is called the chin or mental region), the orbicularis oris muscle, and the mandible in the symphyseal region. See Diogo et al., 2009; Burrows et al., 2011). Every claim on this page comes from the Leumas anatomy graph and carries its source.
What the mentalis muscle is
A muscle of facial expression, innervated by the facial nerve, attached to the skin of the lower lip and inferior to the lower lip (in humans this region is called the chin or mental region), the orbicularis oris muscle, and the mandible in the symphyseal region. See Diogo et al., 2009; Burrows et al., 2011). The atlas records it as a muscle at the organ scale in the human body.
Where the mentalis muscle is
It sits in the head, within the muscular and digestive systems. Not positioned individually. Drawn inside the structure this dataset says contains it — the containment is asserted, the exact spot within it is not.
What the mentalis muscle connects to
The atlas records 11 typed relationships for it, across 6 kinds of connection. part of chin, digestive system and material anatomical entity.

Questions
Where is the mentalis muscle?
It sits in the head, within the muscular and digestive systems. Not positioned individually. Drawn inside the structure this dataset says contains it — the containment is asserted, the exact spot within it is not.
What does the mentalis muscle connect to?
Part of: chin, digestive system and material anatomical entity.
Is the mentalis muscle the same in other species?
Leumas holds the same relationship vocabulary for every species it carries, so where another dataset records this structure you can put the two side by side on /compare.
