Intertragic Notch


We just learned about the Earlobe.

On the outer ear we know about:
- The auricle or pinna, which is the main outside part of the ear
- The helix, which is the folded over part around the outside
- The antihelix, which is the Y shaped bump that sticks out
- The antitragus, which is the bump pointing up that is connected to the earlobe
- The tragus, which is the part closest to the cheek that sticks out
- The earlobe, which is the part that hangs down at the bottom

Another part of the ear is the Intertragic Notch

This is the open space in between the Tragus and AntiTragus.

Earlobe


We just learned about the Tragus.

On the outer ear we know about:
- The auricle or pinna, which is the main outside part of the ear
- The helix, which is the folded over part around the outside
- The antihelix, which is the Y shaped bump that sticks out
- The antitragus, which is the bump pointing up that is connected to the earlobe
- The tragus, which is the part closest to the cheek that sticks out

Another part of the ear is the Earlobe, also called the lobulus auriculae.

This is the soft part of the ear that hangs down at the bottom.
Some people have earlobes that are loose, and other people have earlobes that are touching the side of their face and aren't loose.

Tragus


We just learned about the Antitragus.

On the outer ear we know about:
- The auricle or pinna, which is the main outside part of the ear
- The helix, which is the folded over part around the outside
- The antihelix, which is the Y shaped bump that sticks out
- The antitragus, which is the bump pointing up that is connected to the earlobe

Another part of the ear is the Tragus.

This is the part of the ear that is closest to the cheek.
It sticks out and can be pushed down to close the ear so you can't hear.

Tragus is also the name for the hair that grows around the entrance of the ear.
The name comes from the Greek word τράγος (tragos) meaning goat.

Antitragus


We just learned about the Antihelix.

On the outer ear we know about:
- The auricle or pinna, which is the main outside part of the ear
- The helix, which is the folded over part around the outside
- The antihelix, which is the Y shaped bump that sticks out

Another part of the ear is the Antitragus.

Going up from the bottom of the ear and just connected to the earlobe is the antitragus.
It is a bump that is pointing up.
The shape of this part of the ear helps bring in sounds the way your body wants to hear them.

Human Ear


We just learned about Metastasis and a whole bunch of other things about Cancer.

Let's move on to learn about the Human Ear!

The ear is the part of the human body that takes in sound waves from the air and turns them into messages that our brain can understand.

It also helps balance, telling us when our head is straight up, or tipped over.

Ears are also one place on the body that people have worn jewelry and piercings for thousands of years.

Some people have big ears, some have little ears, and some have ears like an elf but they all help give one of the important 5 senses of the body.
