Histology of the Vocal Folds

Your voice comes from your vocal folds, which are two small pieces of tissue inside your throat that vibrate when you talk. These vocal folds are made up of different layers, kind of like a sandwich.

The top layer is called the epithelium, which is like the bread of the sandwich. It's smooth and flexible, and helps protect the vocal folds from damage.

The middle layer is called the lamina propria, which is like the meat or cheese in the sandwich. It's made up of lots of tiny fibers, and helps the vocal folds vibrate by stretching and contracting.

The bottom layer is called the vocalis muscle, which is like the bottom bun of the sandwich. It's the strongest part of the vocal folds, and it helps control the pitch and volume of your voice.

So, when you talk, air from your lungs passes over your vocal folds, making them vibrate and produce sound. And like a sandwich, all the layers of the vocal folds work together to make sure your voice sounds just right.
