| Question | Answer |
|---|---|
| Helix is the | Outer rim of the ear |
| Origin/termination of the helix | Crus of the helix/lobe |
| Crus is deeper than | the cheek |
| Scapha | Fossa between inner and outer rims of the ear |
| Anti helix | Inner ear rim |
| Antihelix origin/termination | Top of lobe/ upper 1/3 becomes crura, terminates in the superior and anterior portion of the ear |
| Crura | Bifurcation of the anti-helix |
| WHere does the anterior wing of the crura go? | Under the helix |
| Does every one have two crura? | No. |
| Triangular fossa | depression between crura wings |
| Concha | Concave shell of ear, deepest depression, sinks in to the EAM |
| Tragus | elevation protecting ear passage, blends into lobe |
| Antitragus | small eminence obliquely opposite tragus, located on lobe |
| WHere is the only straight line on the ear? | Its attachment point |
| Does the ear change in shape? | No |
| The width is equal to... | 1/3 the length |
| What is the primary anatomical guide? | Ear passage |
| The ear tilts at the same degree as what? | Ramus |
| WHat anatomical feature divides the ear in 1/2 | Zygomatic arch |
| The crest of the ear is always equal to what anatomical feature? | Eye brow |
| Intertragic notch | Space between tragus and anti tragus |
| Lobe | non cartilagenous lowe 1/3 of the ear |
| Middle 1/3 borders | Superior portion of antitragus to superior portion of concha |
| Upper 1/3 | Superior to the concha to crest |
| SHape of nose | pyramidal |
| Types of noses | Leptorrhine, Platyrrhine, Mesorrhine |
| Leptorrhine | long, narrow, prominent bridge |

| Septal cartilidge | Divdes nose in 2, attachd to vomer and ethmoid bone, curves anatomical left |
| Lateral cartilidges | Superior and inferior form sides and tip |
| Dorsum | Protruding ridge |
| Parts of Dorsum | Root, bridge, protruding, tip, convexity |
| Root | concavity inferior to glabella |
| Bridge | roughly triangular projection |
| protruding lobe | spherical angular termination |
| tip | greatest projection |
| Concave profile | Infantine, snub, pug, ski. Depression in the bridge. Has a retrousse (upturned end) |
| WIngs | Lateral lobes, superior to the columna nasi, greatest width. |
| Margins of the wings | Inferior- Arch of the wing Superior- origin of nasolabial fold |
| Columna nasi | Superficial partition between nostrils, most inferior part of the nose, forms right angle with the superior integumentary lip |
| Anterior nares | Nostril openings, oblique position, located in posterior 2/3, greatest depth is medial and posterior. |
