Distinguish between the false vocal cords and true cords?

The false vocal cords and true vocal cords are two important structures involved in voice production. While they are both located in the larynx (voice box), they serve different functions and have distinct anatomical features:

1. False Vocal Cords:

- Also known as the vestibular folds, the false vocal cords are located above the true vocal cords.

- They consist of a pair of thick folds of tissue that do not actively participate in sound production.

- The main role of the false vocal cords is to provide protection to the true vocal cords by acting as a cushion and preventing debris from entering the lower part of the larynx.

- They vibrate at a lower frequency and generate a rustling or creaky sound when they come into contact with each other.

2. True Vocal Cords:

- Also called the vocal folds, the true vocal cords are located below the false vocal cords and play a crucial role in voice production.

- They are made of thin, elastic bands of tissue that vibrate rapidly when air passes through them, producing sound.

- The true vocal cords are controlled by muscles that adjust their tension, length, and position to produce different pitches and vocal sounds.

- The vibration of the true vocal cords creates the fundamental frequency of the voice and allows for the production of various speech sounds, including vowels and consonants.

In summary, the false vocal cords are protective folds located above the true vocal cords and vibrate at a lower frequency, while the true vocal cords are responsible for producing sound through vibration and are involved in speech production.
