Geniohyoid muscle
Understand what you see.
Narrow paired muscle superior to mylohyoid.
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.
- Narrow paired muscle superior to mylohyoid
- Runs from inferior mental spines to hyoid
- Lies near the midline floor of mouth
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.
Examiner-style prompts: identify the structure, explain its relations, then answer the applied follow-up. These are revision questions, not authenticated past papers.
01Identify geniohyoid muscle and justify your identification.+
Narrow paired muscle superior to mylohyoid. Runs from inferior mental spines to hyoid. Lies near the midline floor of mouth.
02What is its nerve supply?+
C1 fibres travelling with hypoglossal nerve; the fibres are cervical, not hypoglossal motor fibres proper.
03What is its action?+
Draws the hyoid anterosuperiorly; with hyoid fixed it can help depress the mandible.
