In M-mode, the y-axis represents what?

Explanation:
In M-mode, the display is laid out so depth is shown along the vertical axis and time advances along the horizontal axis. This means you’re tracking how structures at different depths from the transducer move over time. The vertical axis represents how far tissue lies from the transducer (depth), while the horizontal axis shows the progression of time, allowing you to see motion frame by frame. Echo strength appears as brightness along the trace, not as an axis. So the y-axis is depth.
