STRUCTURE & FUNCTION

Understand what you see.

Forms the muscular cheek wall.

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. Forms the muscular cheek wall
  2. Fibres blend with orbicularis oris
  3. Related to the pterygomandibular raphe
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.

  • Cheek wall
  • Pterygomandibular raphe
  • Parotid duct relation
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 buccinator and justify your identification.
SUGGESTED ANSWER

Forms the muscular cheek wall. Fibres blend with orbicularis oris. Related to the pterygomandibular raphe.

02Is buccinator supplied by the buccal nerve of V3?
SUGGESTED ANSWER

Its motor supply is from buccal branches of VII. The buccal nerve of V3 is sensory.

03What is its function during mastication?
SUGGESTED ANSWER

It keeps food between the occlusal surfaces by compressing the cheek against the teeth.
