Components

(generated)

Component items:

• Face sensory data (face-sensory-data)
  • Face - face skin (face-skin -> LPC.PN.SG.TRG): sensory fibers from the skin
  • Face - parotid skin (face-parotid-skin -> LPC.PN.SG.UDRG): facial skin over the parotid gland
• Face scalp muscles (face-scalp-muscles)
  • Face - corrugator supercilii muscle (LPC.HT.FCM -> face-corrugator-supercilii-muscle): wrinkles forehead
  • Face - depressor supercilii muscle (LPC.HT.FCM -> face-depressor-supercilii-muscle): depression of eyebrow
  • Face - frontalis muscle (LPC.HT.FCM -> face-frontalis-muscle): raises the eyebrows
  • Face - occipitalis muscle (LPC.HT.FCM -> face-occipitalis-muscle): moves the scalp back
• Face upper lip muscles (face-upper-lip-muscles)
  • Face - levator labii superioris muscle (LPC.HT.FCM -> face-levator-labii-superioris-muscle): dilates the nostril; elevates the upper lip and wing of the nose
  • Face - procerus muscle (LPC.HT.FCM -> face-procerus): dilates the nostril; elevates the upper lip and wing of the nose
  • Face - zygomaticus minor muscle (LPC.HT.FCM -> zygomaticus-minor-muscle): elevates upper lip
• Face lower lip muscles (face-lower-lip-muscles)
  • Face - platysma muscle (LPC.HT.FCM -> face-platysma-muscle): draws the corners of the mouth inferiorly and widens it (as in expressions of sadness and fright). Also draws the skin of the neck superiorly when teeth are clenched
  • Face - depressor labii inferioris muscle (LPC.HT.FCM -> depressor-labii-inferioris-muscle): depress the lower lip
  • Face - risorius muscle (LPC.HT.FCM -> risorius-muscle): assist with pulling the lower lip downward and help to tighten the skin over the chin
  • Face - mentalis muscle (LPC.HT.FCM -> mentalis-muscle): elevates and wrinkles skin of chin, protrudes lower lip
  • Face - transverse muscle of the chin (LPC.HT.FCM -> transverse-chin-muscle): assist with pulling the lower lip downward and help to tighten the skin over the chin
• Face surround and mouth corners muscles (face-surround-corner-muscles)
  • Face - orbicularis oris muscle (LPC.HT.FCM -> orbicularis-oris-muscle): pucker the lips
  • Face - zygomaticus major muscle, buccal (LPC.HT.FCM -> zygomaticus-major-muscle-buccal): draws angle of mouth upward and laterally
  • Face - zygomaticus major muscle, proper (LPC.HT.FCM -> zygomaticus-major-muscle-proper): draws angle of mouth upward and laterally
  • Face - levator anguli oris muscle (LPC.HT.FCM -> levator-anguli-oris-muscle): smile (elevates angle of mouth)
  • Face - depressor anguli oris muscle (LPC.HT.FCM -> depressor-anguli-oris-muscle): depresses angle of mouth
