Facial expression at rest (A) using a score of zero and in the last exercise repetition until muscle fatigue (B) using a score of five. The oval dash corresponds to the AU12.

Experimental approaches: (a) Salivary IL-6 and Psychological assessment; (b) Schematics illustrating the experimental design used in this study with iTF: (1) Baseline (neutral picture). (2) Emotional Task was paradigm Muscle by Muscle to Happy facial expression and Pain facial expression. (3) Relaxation by diaphragmatic breathing; (c) Temperature level score and each facial ROI.

Abstracts of facial expression musculature in Pan troglodytes. (a) Lateral view; (b) frontal view. In both diagrams, yellow represents the most superficially located musculature, red represents the most deeply located musculature and orange represents muscles located intermediate to the others. For both views: 1 – superficial head, occipitalis muscle, 2 – deep head, occipitalis muscle, 3 – posterior auricularis muscle, 4 – superior auricularis muscle, 5 – anterior auricularis muscle, 6 – frontalis muscle, 7 – tragicus muscle, 8 – platysma muscle, 9 – risorius muscle, 10 – superficial head, zygomaticus major muscle, 11 – zygomaticus minor muscle, 12 – orbicularis occuli muscle, 13 – levator labii superioris muscle, 14 – levator labii superioris alaeque nasi muscle, 15 – caninus muscle, 16 – depressor septi muscle, 17 – orbicularis oris muscle, 18 – depressor anguli oris muscle, 19 – depressor labii inferioris muscle, 20 – mentalis muscle, 21 – depressor supercilli muscle, 22 – procerus muscle, and 23 – corrugator supercilli muscle.
