Final answer:
The AP diameter, transverse diameter, and glottic aperture of vocal cords differ between males and females. Males tend to have larger dimensions, resulting in deeper voices.
Step-by-step explanation:
The AP diameter, transverse diameter, and glottic aperture of vocal cords differ between males and females. The AP diameter refers to the anteroposterior distance or length of the vocal cords, while the transverse diameter refers to the side-to-side width of the vocal cords. The glottic aperture is the opening between the true vocal cords. In males, these dimensions tend to be larger than in females, which contributes to their deeper voices.
