Canales ossis temporalis
Canalis caroticus. External opening is apertura externa canalis carotici on facies inferior partis petrosae, internal opening is interna canalis carotici on apex partis petrosae.
Canalis nervi facialis begins in depth of meatus acusticus internus, goes up to hiatus canalis nervi
petrosi majoris where it turns 90 degrees creating a knee- geniculum canalis
nervi facialis. Canal continues paralel to pars petrosae axis up to level of eminentia arcuata where it again turns 90 degrees, continue downwards and opens in foramen
stylomastoideum. At downward part of canal it has branches- canaliculus chordae tympani.
Canaliculus chordae tympani begins at down part of canalis nervi facialis and ends in cavitas tympani.
Nerve that goes through it crosses the cavitas tympani and leaves it through fissura
petrotympanica.
Canaliculus tympanicus opens in fossula petrosa on facies inferior partis petrosae, goes to cavitas tympani.
Canalis musculotubarius contains semicanalis musculi tensoris tympani and semicanalis tubae
auditivae. Its external opening is on facies inferior partis petrosae next to margo
anterior. Its internal opening is in cavitas tympani.
Canaliculus cochleae opens on facies inferior partis petrosae next to incisura jugularis and goes to
cochlea.
Canaliculus vestibuli opens on facies posterior partis petrosae and goes to vestibulum.
Canaliculus caroticotympani goes from canalis caroticus to cavitas tympani.
