Exploring the fascinating world of bone biology… This month, our Bone of the Month series takes us to a small, discreet, yet truly unique bone of the human skeleton: the hyoid bone!

Located in the neck, just below the mandible and above the larynx, the hyoid is a small, U-shaped bone, typically measuring around 3-4 cm across.

Unlike all other bones, it does not form a joint with any other bone. Instead, it is suspended and stabilized by a complex network of muscles and ligaments.

Despite its small size, the hyoid plays an essential role in several everyday functions:

🗣️ Speech and voice production
🍽️ Swallowing and tongue movements
🌬️ Airway support and breathing

𝐈𝐧 𝐩𝐫𝐞𝐜𝐥𝐢𝐧𝐢𝐜𝐚𝐥 𝐫𝐞𝐬𝐞𝐚𝐫𝐜𝐡, the hyoid bone and its surrounding structures are relevant for:

✅ Investigating swallowing mechanisms and oropharyngeal function
✅ Studying craniofacial and upper airway anatomy
✅ Understanding musculoskeletal interactions and biomechanics
✅ Exploring bone morphology and anatomical variations through microCT and histological analyses

💡 Fun fact: This unusual bone also plays an important role in forensic sciences. Its examination can provide valuable clues during post-mortem investigations, particularly in cases of suspected neck compression or strangulation.

A tiny bone with a surprisingly important role, both in life and in forensic investigations!

At Atlantic Bone Screen, we explore the complexity of bone biology across different anatomical structures, combining imaging, histology and quantitative analyses to support preclinical and translational research.
