Maxilla

00:02 Now let's take a look at the maxilla.

00:06 Here we see the anterior surface with little fossa called incisive fossa.

00:12 Which are fossa, related to teeth.

00:16 We also have canine fossa, again relating to teeth this time the canines.

00:22 We also have openings or phenomena just below the orbit called the infraorbital foramen.

00:29 We also have a portion of the orbit this time the infraorbital margin.

00:36 There's also an area around the nose that we call the nasal notch.

00:41 And towards the midline, a group called the nasal spine.

00:48 Here we have the infratemporal surface, the zygomatic process of the maxilla and alveolar canals.

00:57 Alveolar again in this context means referring to the hollow or tooth socket.

01:03 So these are canals that have something to do with the sockets relating to the tooth.

01:09 Here we have a bump called the maxillary tuberosity.

01:14 To which muscles are going to attach.

01:18 Here we look at the orbit and we can see that it's forming a good portion of the inferior aspect of the orbital surface.

01:25 And a little bit of the lacrimal area called the lacrimal notch.

01:31 There's also an anterior edge here of the inferior orbital fissure through which multiple cranial nerves pass.

01:40 There's a groove along the inferior surfaces of the orbit here called the infraorbital groove.

01:47 If we take the bone out, we're able to see the medial aspects which are the nasal surfaces.

01:53 And we can see a little hiatus called the maxillary hiatus.

01:58 To be this little opening into the maxillary sinuses.

02:03 We have a little groove called the lacrimal groove that's going to participate in the drainage of tears.

02:10 A little crest as the name implies for concha called the conchal crest.

02:16 And then a groove more posteriorly called the greater palatine groove.

02:24 We have the zygomatic process.

02:27 Frontal process.

02:32 And alveolar processes.

02:34 All interacting with the areas you would expect.

02:37 Like ematic bone frontal bone, and in the terms of alveolar.

02:41 Having to do with the upper teeth.

02:43 While it's have a palatine process, which forms a portion of the hard palate.
