Micro-Learning — Module 03.01

Facial muscle anatomy

A structured clinical approach to the muscles of facial expression — from the dermal insertions that make them behave unlike any other muscle group, through region by region, to the anatomical danger zones that set the boundary on every injectable decision.

4 units ~8 min each 12 checkpoints Level: All levels — tiered content TGA compliant

Unit 1 Foundations & the SMAS Why mimetic muscles insert into skin, how agonist and antagonist balance governs the result, and the SMAS layer that defines the injection planes. 3 checkpoints · ~8 min Not started Unit 2 Upper face Frontalis as the only brow elevator, the four-muscle glabellar complex, and the diffusion pathway behind upper eyelid ptosis. 3 checkpoints · ~8 min Not started Unit 3 Mid & lower face Fifteen nasal, midface and perioral muscles converging on the modiolus, the variation between patients, and the placement limits that keep effect inside the target. 3 checkpoints · ~8 min Not started Unit 4 Neck & danger zones The platysma as the inferior continuation of the SMAS, and six high-risk zones stratified by whether they connect to the ophthalmic circulation. 3 checkpoints · ~8 min Not started

Each unit follows the same rhythm: a short piece of clinical content, a checkpoint that asks you to commit to an answer, then the reasoning behind it. Checkpoints are not scored and cannot be retried — committing to a position before seeing the answer is the point of the exercise. Your progress is stored on this device only.

Next step. This module is the anatomical foundation for the Injector Series. Once you have completed it, Module INJ.01 — Neuromodulators applies the same anatomy to treatment decision-making.
