your posterior division and anterior division.
So that brings us to the parotid gland.
Parotid gland is here, I won’t go through
the surface anatomy for this session, because
it’s not relevent to you. But you need
to understand that it has got a superficial
lobe and a deep lobe. The lobe is split
by your facial nerve running in between.
So the facial nerve splits it into the superficial
lobe and deep lobe. What are the other structures
in relation to the parotid gland? What you’re
asked in the exam, what other structures
are here? Retromandibular vein?
Retromandibular vein. As the name says, retromandibular,
behind the mandible, so it’s quite posterior.
What is within the substance of the parotid,
if you take off the gland? What other structures?
So you have a nerve.
External carotid. Branches. Main branches of the
external carotid. So you have the maxillary
artery and the superficial temporal. The main
branches of external carotid are within the
substance of the parotid gland. And
then clearly the retromandibular vein.
Then we said about the facial nerve, the branches.
Temporal, zygomatic, buccal, marginal mandibular
and cervical. So once it comes out of the
stylomastoid foramen, these are the five branches,
Now here we mentioned about a couple of
these muscles. I have seen questions on this
bit. You know, the posterior belly of digastric
nerve supply, is a branch from the facial.
They get a branch from the facial which
is supplying the posterior belly of digastrics.
This is a little bit confusing if you haven’t
read it because you suddenly think, “Which
nerves supplying the neck?” All these strap
muscles are by ansa cervicalis, then you have
the nerve to mylohyoid supplying the mylohyoid,
then you have the anterior belly of the digastric
and the posterior belly. Anterior belly is
usually coming off the mandibular division
here and the posterior belly is coming of
the facial. We discussed about the common carotid
