• Facial region
  • Superficial muscle-cutaneous muscle
  • Muscles of the lips and cheeks
  • Muscles of the nostrils
• Palpebral region (muscles of the eyelids)
• Auricular region (muscles of the external ear)
• Temporo-maxillary region (mandibular muscles -masseter, pterygoid, temporal, etc,)
• Hyoid region- (hyoid muscles)
• Orbital region (ocular muscle)
