gracilis

The most superficial muscle on the medial side of the thigh. It is thin and flattened, broad above, narrow and tapering below. It arises by a thin aponeurosis from the anterior margins of the lower half of the symphysis pubis and the upper half of the pubic arch. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the gracilis is

The most superficial muscle on the medial side of the thigh. It is thin and flattened, broad above, narrow and tapering below. It arises by a thin aponeurosis from the anterior margins of the lower half of the symphysis pubis and the upper half of the pubic arch. The atlas records it as a muscle at the organ scale in the human body.

Where the gracilis is

It sits in the lower limb, within the muscular system. Positioned deliberately as part of this species body plan.

What the gracilis connects to

The atlas records 8 typed relationships for it, across 4 kinds of connection. part of hindlimb stylopod, hip and musculature of hip.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the gracilis. 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 gracilis muscle and musculus gracilis. Searching any of those names reaches this page.

Questions

Where is the gracilis?

It sits in the lower limb, within the muscular system. Positioned deliberately as part of this species body plan.

What does the gracilis connect to?

Part of: hindlimb stylopod, hip and musculature of hip.

Is the gracilis 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.
