What is the hyoid bone and where is it located?

The hyoid bone is a U-shaped bone in the anterior neck at the level of the C3 vertebra. It is unique because it does not articulate with any other bone, being suspended by ligaments from the temporal bones.

What are the main parts of the hyoid bone?

The hyoid bone consists of five parts: Body (central portion), Greater cornua (2 horns projecting backward), and Lesser cornua (2 small projections at the body-cornu junctions).

Why is the hyoid bone important for swallowing and speech?

The hyoid bone serves as a crucial attachment site for muscles involved in swallowing and speech. Its suspended position allows it to move freely, facilitating these functions.

What is the clinical significance of the hyoid bone in forensic investigations?

A fracture of the hyoid bone is a key indicator of strangulation or throttling in forensic cases, making it important for determining cause of death.

How is the hyoid bone used as a surgical landmark?

The greater cornua serve as a landmark for locating the lingual artery during neck surgeries. Their tips can be palpated near the anterior border of the sternocleidomastoid muscle.

What attaches to the lesser cornua of the hyoid bone?

The stylohyoid ligament attaches to the tips of the lesser cornua. These small projections may become ossified over time.

How can you palpate the hyoid bone?

The tips of the greater cornua can be felt midway between the laryngeal prominence (Adam's apple) and the mastoid process, near the anterior border of the sternocleidomastoid muscle.
