- Muscles regarding Neck & head movement
- Anterior & lateral (flex head and neck, lateral flex)
- SternoCleidoMastoid : flex head & neck, laterally flex ipsilateral, rotate contralateral
- Scalene : anterior/middle/posterior : flex head & neck, laterally flex ipsilateral, rotate contralateral
- Longus capitis / Longus colli(cervicis) : flex head & neck, laterally flex ipsilateral, rotate ipsilateral
- Posterior (extend head and neck, lateral flex)
- Upper Trapezius : extend head & neck, laterally flex ipsilateral, rotate contralateral
- Levator Scapulae : extend head & neck, laterally flex ipsilateral, rotate ipsilateral
- Splenius capitis/ cervicis : extend head & neck, laterally flex ipsilateral, rotate ipsilateral
- Subocccipital : extend & rotation head and neck
- Anterior & lateral (flex head and neck, lateral flex)
- Muscles regarding mastication
- Masseter : elevate mandible, protract mandible
- Temporalis ; elevate mandible, retract mandible
- Digastric : depress mandible, retract mandible
- Medial pterygoid : elevate mandible, protract mandible, laterally deviate contralateral(unilaterally)
- Lateral pterygoid : protract mandible, laterally deviate contralateral(unilaterally)
- Muscles regarding hyoid bone
- Suprahyoids(geniohyoid,mylohyoid, stylohyoid) : elevate hyoid and tongue, depress mandible
- Infrahyoids(sternohyoid, sternothyroid, thyrohyoid, omohyoid) : depress hyoid bone and thyroid cartilage
