Ten Zulus Buggered My Cat has more of a ring to it in my humble opinion!

Seb: The facial nerve gives off many branches as it passes from the pontine angle, through the facial canal to the stylomastoid foramen. Of particular note are the petrosal nerves (which help to form both the saphenopalatine ganglion and otic ganglion), the branch to stapedius and the chorda tympani (all within the facial canal) & the posterior aurticular nerve and the nerves to digastric and stylohyoid (at the stylomastoid foramen). The five infamous braches are the TERMINAL branches of the nerve. They are the ones which form the big spaghetti-like mess within the parotid gland.

If its a spotter, i would be surprised if they asked you to identify anything other than the 5 terminal branches, however they could always ask you a subsequent question about them. It all makes sense if you have a look at a picture of the nerve path and its branches in Gray's Anatomy - if you are in a rush there is a copy on Wikipedia.

All the best,
