Gluteus medius
Understand what you see.
Abducts hip and stabilises pelvis during single-leg support.
Zoom into the original labels. Practise pointing out each structure, then explain it aloud. Diagrams are teaching references; specimen appearance and slide staining vary.
How to recognise it.
- Fan-shaped muscle on lateral ilium
- Deep to part of gluteus maximus
- Inserts on greater trochanter
Point them out.
Tap a number to open its reference, zoom in and locate the structure. Numbers stay the same across views. This key follows landmarks visible in the reference images.
Think first. Then reveal.
Say your answer aloud before opening the suggested response.
01How do you identify gluteus medius?+
Fan-shaped muscle on lateral ilium. Deep to part of gluteus maximus. Inserts on greater trochanter.
02Explain a positive Trendelenburg sign.+
When standing on an affected limb, weakness of its hip abductors allows the opposite side of the pelvis to drop.
03Which nerve supplies medius and minimus?+
Superior gluteal nerve, usually L4–S1.
04What is its main functional or developmental significance?+
Abducts hip and stabilises pelvis during single-leg support. Key structures to recognise: Iliac origin; Greater trochanter; Superior gluteal nerve.
