Zygomatic Bone

00:01 Now we have the zygomatic bone.

00:04 Which is very complicated as well and it has a lateral facial surface.

00:10 That's going to participate in the formation of what we call the cheekbones.

00:15 And we can see it has parameters such as the zygomaticofacial parameter.

00:20 Through which structures like nerves are going to pass.

00:23 It's also going to be the attachment point for certain muscles of facial expressions.

00:27 Such as zygomaticus major.

00:29 And zygomaticus minor.

00:33 Here we see the posteromedial or temporal surface of the bone.

00:40 And if we zoom in, we can see zygomaticotemporal foramina.

00:45 Again, these are openings passageways for nerves to pass through.

00:50 Here we see its orbital surface so it participates in part of the bony orbit.

00:55 Here you can see the anterosuperior orbital border which is also forming the orbital border.

01:01 The anteroinferior border also forming the maxillary border.

01:05 The posterior superior border which is also the temporal border.

01:10 As well as his posterior inferior and posterior medial borders.

01:17 Now let's look at the processes coming off of the zygomatic bone.

01:21 First we have the frontal process interacting with the frontal bone.

01:26 And it's going to interact with the zygomatic process of the frontal bone.

01:30 So they're correspondingly named.

01:33 We also have the temporal process.

01:36 Which is going to interact with the zygomatic process of the temporal bone together forming the zygomatic arch.
