  "answer": "Path variables from a URL are captured and made available to handlers primarily through the following functions:\n\n1. **`.Path()`** - Located in `mux.go` at line 366, this method is responsible for handling the path of the route.\n2. **`.Handle()`** - Located in `mux.go` at line 329, this method is used to register a handler for a specific route.\n3. **`.HandleFunc()`** - Located in `mux.go` at line 335, this function allows you to register a handler function for a specific route.\n\nAdditionally, the function **`.prepareVars()`** in `route.go` at line 815 is involved in preparing the variables extracted from the URL path."
