INSIDE A BONE | STUDENT WALKTHROUGH Anatomy in Minutes https://anatomyinminutes.com/skeletal-lab Edited screen captures of the live classroom simulation, captured October 2, 2026. Synthetic narration. This prepared-specimen model simplifies anatomy and skips surgical preparation; use it only on screen. 00:00:00 Welcome to the skeletal lab Welcome to the skeletal lab, an edited classroom simulation. Work only on screen. 00:00:07 Start fresh, if needed If earlier progress appears, choose Reset specimen. Your notebook answers are kept. 00:00:13 Reveal the femur First, predict what is inside a long bone. Then choose Move muscles aside. 00:00:20 Lift the femur onto the tray Choose Lift femur onto tray, or drag across the specimen. Watch the same femur leave its tissue bed and move onto the tray. 00:00:30 Open the dissection Choose the Begin dissection button. 00:00:34 1. Open the thin covering The scalpel is selected for you. Press and drag anywhere across the bone to open the thin covering. No precision tracing is needed. 00:00:44 2. Remove the membrane Next, drag with the forceps. The thin outer membrane is removed, revealing compact bone. 00:00:52 3. Cut the bone window Now drag with the powered bone saw. Its small oscillating blade follows the outlined window in the hard compact bone. 00:01:02 4. Lift the solid section Use the forceps again. Drag to lift the cut section as one solid piece. Hard bone does not peel. 00:01:11 5. Inspect all four structures Select all four structures. Read each observation and function card below the model. 00:01:18 Compact bone Compact bone forms the dense, strong outer wall. 00:01:23 Spongy bone Spongy bone is hard and branching, not a soft sponge. 00:01:28 Red bone marrow Red marrow produces blood cells within some of the spaces. 00:01:33 Yellow bone marrow Yellow marrow in the shaft cavity stores fat. 00:01:38 Record your own evidence Use the numbered notebook prompts. Explain your observations with your class notes. Apply what you learned to the helmet, backpack, and kicking a ball questions. 00:01:50 Save your work Download or print your notes. Answers stay on this device, with no automatic submission. Follow your teacher’s directions to turn them in. Production: free local Kokoro Michael (am_michael) synthetic narration and FFmpeg.
