[2025-09-29T13:52:18.125190] [PI reasoning] **Identifying similar structures**

I'm thinking about the tendons of the gracilis, sartorius, and semitendinosus muscles that form the pes anserinus, meaning "goose’s foot" at the tibia. I wonder if a similar structure could be found elsewhere. Maybe in the parotid gland, where the facial nerve divides into branches resembling that configuration. This could be termed the "parotid plexus" or "pes anserinus superficialis parotidei." So, I’d lean toward the parotid gland for this question.
