mixed- but mainly mucous
What are the intrinsic muscles of the tongue?
transverse, vertical
superior longitudinal
inferior longitudinal
What are the extrinsic muscles of the tongue?
palatoglossus, hyoglossus, genioglossus, styloglossus
What is the motor nerve supply of the tongue?
all supplied by hypoglossal
apart from: palatoglossus- vagus
What provides sensation nerve supply to tongue?
sensation: anterior 2/3 - lingual nerve- branc of v3 - mandibular divison trigeminal
but gustative sensation to ant 2/3 = chorda tympani
post 2/3 - glossopharyngeal
What is the origin, insertion and function of:
Masseter
Temporalis
Medial Pterygoid
Lateral Pterygoid
Masseter – O: inf.border of zyg.arch. I: Angle of mand. N: masseteric branch of V3. A: elevate and protrude mand.
Temporalis – O: temporal fossa. I: coronoid process and ant.border of ramus. N: temporal branch of V3. A: elevate
and retrude mand.
Medial Pterygoid – O: DEEP – med.surface of lat.ptery.plate. SUPER – max.tuberosity. I: angle of mand. N:
med.ptery.branch of V3. A: elevate and protrude mand.
Lateral Pterygoid – O: SUP – great wing of sphenoid. INF – lat.surface of lat.ptery.plate. N: lat.ptery branch of V3. A:
depress, protrude and lateral deviation of mand.
