psoas minor muscle
The psoas minor is a long, slender skeletal muscle that, when present, is placed in front of the psoas major muscle. [WP,unvetted]. Every claim on this page comes from the Leumas anatomy graph and carries its source.
What the psoas minor muscle is
The psoas minor is a long, slender skeletal muscle that, when present, is placed in front of the psoas major muscle. [WP,unvetted]. The atlas records it as a muscle at the organ scale in the human body.
Where the psoas minor muscle is
It sits within the muscular system. Not positioned individually, and containment is not asserted either. Drawn near structures of the same kind, which is a weak claim about location.
What the psoas minor muscle connects to
The atlas records 4 typed relationships for it, across 4 kinds of connection. a kind of prevertebral muscle.
Supply and innervation
This dataset asserts no arterial supply, venous drainage or innervation for the psoas minor muscle. Only a minority of structures carry those edges here, so an empty answer means nothing has been recorded — not that there is nothing to record.
Also called
Also recorded as psoas minor and m. psoas minor. Searching any of those names reaches this page.

Questions
Where is the psoas minor muscle?
It sits within the muscular system. Not positioned individually, and containment is not asserted either. Drawn near structures of the same kind, which is a weak claim about location.
What does the psoas minor muscle connect to?
A kind of: prevertebral muscle.
Is the psoas minor 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.
