How is a goroutine placed in the global scheduler queue in Go?

In Go, when a goroutine is started using the go keyword, a goroutine object is created and placed in the global scheduler queue. The Go scheduler is an M:N scheduler that maps many goroutines (G) to fewer system threads (M).

When go function() is called, a goroutine is created and added to the global runnable goroutine queue. The scheduler periodically selects goroutines from this queue and assigns them to available system threads for execution.

Thus, placing a goroutine in the global queue occurs automatically upon its creation, and the scheduler manages their distribution and execution without developer intervention.
