Parotid Gland

00:01 your posterior division and anterior division. So that brings us to the parotid gland.

00:02 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.

00:22 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.

00:40 What is within the substance of the parotid, if you take off the gland? What other structures? So you have a nerve. External carotid? 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.

01:02 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
