Question 3

Protruding lobe/Tip

Answer 3

the protruding lobe is the spherical structure
the tip is the very end point

Question 4

Wings

Answer 4

Ala
Each wing comprises 1/4 of the width of the nose
Protruding lobe creates 1/2 the width (in the center)

Question 5

Arch of the Wing

Answer 5

An upward concavity of the nostril rim that rises superiorly

Question 6

Columna nasi

Answer 6

Most inferior part of the nose
Narrower at the anterior
Wider at posterior

Openings of the nostrils
Shaped like pears, almonds, kidney beans

Question 8

Sides of the nose

Answer 8

Lateral sides of the nose
Gently blends into the cheek

Question 9

Anatomical structures of the nose (bones and cartilage forming the nose)

Answer 9

Nasal bones
Nasal spine of the maxillae
Cartilage
Septum

Question 10

Nasal spine

Answer 10

Spina is Latin for “thorn”
The two maxillae combine to form the nasal spine

Question 11

Cartilage of the nose

Answer 11

Two Superior lateral cartilage
Two Inferior lateral cartilage
One interior

Question 12

Inferior lateral cartilage

Answer 12

A.K.A. Alar cartilage
Create the roundness of the protruding lobe
May create a small cleft in nose

Each portion of the cartilage angles posteriorly at the midline to create the columna nasi

Question 13

Answer 13

Lend support to the covering tissue
of the upper part of the nose

Question 14

Septum Cartilage

Answer 14

Large, thin, vertical cartilage that separates the nasal cavity left from right
It is anchored to the nasal, ethmoid and vomer bones

Question 15

What make up the most superficial margins of the Nasal Cavity

Answer 15

Nasal bones and Maxillae

Question 16

Nasal Index

Answer 16

Created by Paul Topinard
Historically used to classify racial differences by the size and shape of the nose

Calculation is made by measuring (in centimeters)the width divided by the height, multiplied by 100

narrow - Leptorrhine= thin=<70
middle - Mesorrhine=middle=70-84.9
wide - Platyrrhine=plat/flat=<85

Question 17

Narrow Nose

Answer 17

• Leptorrhine Nose
• thin=<70

Question 18

Middle Nose

Answer 18

• Mesorrhine Nose
• Middle=70-84.9

Question 19

Wide Nose

Answer 19

• Platyrrhine
• plat/flat=<85

Question 20

Nose Profiles

Answer 20

Straight - Greek
Convex - Roman
Concave - Infantine

Question 21

Straight Nose Profile

Answer 21

• Greek Nose
• Marked by a recession at the root
• Straight inclination all the way to the tip

Question 22

Convex Nose Profile

Answer 22

• Roman Nose or Aquiline nose (eagle)
• Recession at the root
• Convex curve present throughout the inclination or a short convex bump

Question 23

Concave Nose Profile

Answer 23

• Infantine Nose, Retrousse nose, pug nose
  (Retrousse: French for “rolled up”)
• Recession of root extends into the concavity of the inclination
• or inclination is mostly straight with small concavity present
