Digastric muscle

Two muscular bellies joined by an intermediate tendon. Tendon is held near the hyoid. Anterior and posterior bellies have different nerve supplies.

Zoom in, then drag to inspect. Keyboard: + / − to zoom, arrows to pan, 0 to reset. Tap the numbered markers to explore parts.

STRUCTURE & FUNCTION

Understand what you see.

Two muscular bellies joined by an intermediate tendon.

Zoom into the original labels. Practise pointing out each structure, then explain it aloud. Diagrams are teaching references; specimen appearance and slide staining vary.

01 / IDENTIFICATION

How to recognise it.

  1. Two muscular bellies joined by an intermediate tendon
  2. Tendon is held near the hyoid
  3. Anterior and posterior bellies have different nerve supplies
02 / KEY STRUCTURES

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.

03 / VIVA PRACTICE

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 digastric muscle and justify your identification.
SUGGESTED ANSWER

Two muscular bellies joined by an intermediate tendon. Tendon is held near the hyoid. Anterior and posterior bellies have different nerve supplies.

02Give the nerve supply of each belly.
SUGGESTED ANSWER

Anterior belly: nerve to mylohyoid from V3. Posterior belly: facial nerve VII.

03Which neck triangle lies between the anterior bellies?
SUGGESTED ANSWER

The submental triangle, with the hyoid forming its inferior boundary.
