17
Q

The Antitragus is….

A

is an L-shaped flap.

18
Q

This is opposite to the Tragus and inferior to the Antihelix Tail

A

What is the Antitragus

19
Q

This flap projects over the lower Inferior Concha and has a distinct curved groove separating it from the Antihelix and the less distinct crevice where it meets the Intertragic Notch

A

The Antitragus location

20
Q

The location of the Intertragic Notch is

A

The curved intersection of the Tragus and Antitragus

21
Q

This area is the curved intersection of the Tragus and the Antitragus

A

What is the Intertragic Notch

22
Q

Where is the Lobe located?

A

At the base of the external ear

23
Q

This is a “U”-shaped soft fleshy tissue region at the base of the external ear

A

What is the Lobe?

24
Q

Where is the Scaphoid Fossa?

A

Between the Helix and Antihelix - it is the crescent shaped groove.

25
Q

What does “Fossa” mean (Scaphoid Fossa)?

A

A fissure or crevice

26
Q

What does Scaphoid refer to (Scaphoid Fossa)?

A

The scaffolding used to form the outer structure of a boat or building during construction. “Scapha” thus refers to boat shaped

27
Q

Triangular Fossa is located…

A

Between the Superior Crus and the Inferior Crus of the Antihelix, it is the triangular groove and is shaped like a Gothic arch on its side

28
Q

This traiangular goove is between the Superior Crus and the Inferior Crus of the Antihelix

A

What is the Triangular Fossa

29
Q

This is shaped lie a Gothic arch on its side

A

What is the Triangular Fossa?

30
Q

What does Concha refer to?

A

The Conch sea shell

31
Q

This is a shell-shaped valley at the very center of the ear?

A

What is the Concha

32
Q

The Superior Concha is located

A

Below the Inferior Crus

It is the Upper Hemiconcha

33
Q

The Inferior Concha is located

A

Next to the Ear Canal

It is the Lower Hemiconcha

34
Q

The Concha Ridge divides…

A

the Superior Concha and Inferior Concha

35
Q

This is the extension of the Helix Root onto the Concha floor

A

What is the Concha Ridge?

36
Q

What is the Concha Wall?

A

The hidden, vertical region of the ear which rises up from the Concha floor.

37
Q

The Concha Wall description (long explanation)

A

The Wall of the Antitragus is the vertical Concha region underneath the Antitragus, overlying the lower Inferior Concha, whereas the Wall of the Antihelix is the curving, vertical surface which rises from the floor of the Concha up to the Antihelix ridge

38
Q

The subtragus definition is:

A

The underside of the Tragus, overlying the Ear Canal

39
Q

The hidden, underside portion of the brim of the Helix is

A

The Internal Helix

40
Q

This lies over the Ear Canal

It is the underside of the Tragus

A

What is the Subtragus

41
Q

What is the Internal Helix?

A

The hidden, underside portion of the brim of the Helix
