Anterior posterior diameter of vocal cords in both males & females is ?
## Core Concept
The anterior-posterior (AP) diameter of the vocal cords is an important anatomical measurement in the larynx, relevant to both males and females. This measurement can affect voice production and laryngeal function.
## Why the Correct Answer is Right
The correct answer states that the AP diameter of the vocal cords in both males and females is 20-25 mm. This range is generally accurate and reflects the typical anatomical dimensions. The size of the vocal cords, including their AP diameter, is larger in males than in females, but the provided range accommodates both genders.
## Why Each Wrong Option is Incorrect
- **Option A:** This option suggests a range that is too narrow or not accurate for both males and females.
- **Option B:** Similarly, this option does not accurately represent the typical AP diameter for both genders.
- **Option D:** This option provides a range that is not correct for the AP diameter of vocal cords in both males and females.
## Clinical Pearl / High-Yield Fact
A key clinical point to remember is that the size and tension of the vocal cords significantly influence voice production. The larger vocal cords in males typically produce deeper voices, while the smaller cords in females produce higher-pitched voices.
## Correct Answer: B. 20-25 mm.
