gl. parotis ductus parotideus ln. parotideus n. facialis n. auriculotemporalis
Gl. parotis
Located between gl. mandibularis and the ear
Ductus parotideus
- Runs over m. masseter*
- Opens into oral vestibule, approx. P4*
Ln. parotideus
Between m. masseter and gl. parotis
N. facialis (CN-VII)
From caudal border of the pons, exiting skull at for. stylomastoideum
