[Radio-anatomic data concerning the hyoid bone and its dynamics]

Area of Science:

• Anatomy
• Speech Science
• Biomechanics

Background:

• The hyoid bone's role in human speech is a topic of interest.
• Understanding hyoid bone movement is crucial for speech articulation studies.

Purpose of the Study:

• To investigate the positional variations of the human hyoid bone during speech articulation.
• To explore the relationship between hyoid bone movement and phoneme production.

Main Methods:

• Analysis of anatomical sections.
• Review of X-ray images.
• Examination of radiocinema recordings.

Main Results:

• The hyoid bone exhibits variable positions during speech articulation.
• Movement patterns include horizontal, vertical, and sinusoidal translations.
• Stylohyoid suspension allows for diverse hyoid bone movements.

Conclusions:

• The hyoid bone's position is dynamic and phoneme-dependent.
• Hyoid bone mobility is integral to speech articulation.
• Hyoid bone function may have influenced the evolution of human speech.
