The bone that is horn-shaped is called the hyoid bone.
The hyoid bone is a unique, horseshoe-shaped (or "U" shaped which can resemble horns in some individuals) bone located in the anterior midline of the neck between the chin and the thyroid cartilage. It is distinct because it does not articulate with any other bone in the body. Instead, it is suspended from the skull by muscles and ligaments.
Here's some key information about the hyoid bone:
- Location: Situated in the neck, just above the larynx (voice box).
- Function: Primarily serves as an anchor point for muscles associated with swallowing and speech. It supports the tongue and provides attachment points for muscles of the larynx, pharynx, and tongue.
- Structure: Consists of a body, two greater horns (cornua), and two lesser horns (cornua). The "greater horns" are the elongated, horn-like projections that extend posteriorly from the body of the hyoid.
- Importance: Plays a critical role in maintaining an open airway during breathing.
In summary, while the hyoid bone itself isn't solely shaped like a horn, its greater horns project backwards, giving it a somewhat horn-like appearance. It's essential for speech, swallowing, and breathing.
