Leg & foot muscles

Fibularis longus and brevis

STRUCTURE & FUNCTION

Understand what you see.

Evert the foot and assist plantarflexion; longus supports arches.

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. Lateral leg compartment
  2. Tendons pass behind lateral malleolus
  3. Longus crosses plantar foot
02 / KEY STRUCTURES
