What Is Hyoid Bone Horse?
The hyoid apparatus is a Y-shaped group of bones that joins onto the skull and provides attachment for several muscles, including the tongue. The muscles that control the tongue and airways, including those that attach to the hyoid apparatus are small and sit deep between the horse’s ‘jawbones’ (the mandibular rami).

What is special about the hyoid bone?
Famously, the hyoid bone is the only bone in humans that does not articulate with any other bone, but only has muscular, ligamentous, and cartilaginous attachments. Given this peculiarity, it has been described as “free floating” [1].

- Superior. Middle pharyngeal constrictor muscle. Hyoglossus muscle. Genioglossus. Intrinsic muscles of the tongue. Suprahyoid muscles. Digastric muscle. Stylohyoid muscle. Geniohyoid muscle.
- Inferior. Thyrohyoid muscle. Omohyoid muscle. Sternohyoid muscle. Sternothyroid muscle.

Can the hyoid bone be broken?
Injuries to the hyoid bone are rare. The most commonly reported injury is fracture, yet this is often a post-mortem finding, with an incidence of between 17–76 %, in victims of strangulation and hanging. In survivors it is more often associated with a trauma other than manual strangulation.
Is the hyoid bone the Adam’s apple?
The hyoid bone is located above the Adam’s apple in the neck, and is attached to muscles of the tongue and other soft tissues in the throat. This bone moves around, and this mobility may allow the area to collapse and cause airway blockage during sleep.
