cervical branch of VII

draws corner of mouth infr + widens mouth

draw skin of neck supr when clenched

24
Q

ant belly digastric inn + funct

A

mylohyoid (CNV3)

depress mandible

elevate/steadies hyoid during speech and swallow

25
Q

post belly digastric inn + funct

A

CNVII

depress mandible, elevates/steadies hyoid during speech and swallow

26
Q

mylohyoid muscle inn+ funct

27
Q

hyoglossus muscle inn + funct

A

CNXII

depress + retract tongue

28
Q

Middle Pharyngeal Constrictor Muscle inn + funct

Q

trace sublingual + submandibular innervation

which foramen?

A
  1. CNVII para/pre (along w/ SS) from superior salvitory Nu
  2. travel into chorda tympani (petrotympanic fissure) -> lingual
  3. synpase in submandibular ganglion (SA, VE-sym/post don’t synpase)
  4. para/post -> leave ganglion to innervate submand gland
  5. para/post -> rejoin lingual n to reach sublingual gland
30
