Epiglottis

Locate epiglottis on this anatomical reference. Read the original plate labels to confirm the view and adjacent structures.

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.

Tenses and lengthens the vocal folds.

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. External muscle between cricoid arch and thyroid cartilage
  2. Tilts thyroid relative to cricoid
  3. An exception to recurrent-laryngeal motor supply
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.

Related features & study points (3)

Additional relations, attachments or microscopic details to revise alongside this plate. These are separate from its numbered image landmarks.

  • Origin: cricoid arch
  • Insertion: thyroid lamina/horn
  • Motor: external laryngeal nerve
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 cricothyroid muscle and give its main role.
SUGGESTED ANSWER

External muscle between cricoid arch and thyroid cartilage. Tilts thyroid relative to cricoid. An exception to recurrent-laryngeal motor supply. Tenses and lengthens the vocal folds.

02What nerve supplies it?
SUGGESTED ANSWER

External branch of superior laryngeal nerve, from vagus X.

03What functional problem may follow its denervation?
SUGGESTED ANSWER

Reduced ability to tense the folds and reach higher pitch; this differs from a sensory deficit caused by internal laryngeal injury.

04Point out three important relations and explain their significance.
SUGGESTED ANSWER

Origin: cricoid arch; Insertion: thyroid lamina/horn; Motor: external laryngeal nerve. Tenses and lengthens the vocal folds. Use the reference plate to locate the region; the relationship map organises the associations and is not drawn to scale.
