The lobule is the fleshy, lower part of the pinna, or outer ear.
What is lobule in the human body?
The lobule is often used as a landmark for measuring hearing loss, as it is relatively easy to identify. It is the only part of the outer ear that does not contain cartilage.
What is the function of the lobule of the ear?
The lobule does not have any specific function. It is thought to be a vestigial organ, meaning that it is a remnant of an organ that was once functional in our ancestors. However, the lobule does serve as a useful landmark for measuring hearing loss and other ear problems.
What is the difference between ear lobe and lobule?
The terms “ear lobe” and “lobule” are often used interchangeably. However, there is a slight difference between the two terms. The ear lobe is the fleshy part of the ear that hangs down, while the lobule is the entire lower part of the pinna, including the ear lobe.
Why is my lobule swollen?
There are a number of reasons why your lobule might be swollen. Some of the most common causes include:
- Infection: An infection of the lobule, such as an earlobe piercing infection, can cause swelling.
- Trauma: Injury to the lobule, such as a blow to the ear, can also cause swelling.
- Allergic reaction: An allergic reaction to a metal in a piercing or to a medication can cause swelling of the lobule.
- Lupus: A chronic autoimmune disease called lupus can cause swelling of the lobule.
If your lobule is swollen, it is important to see a doctor to determine the cause and get treatment.
