Definition

noun

The Latin term for hyoid apparatus, which is a group of bones below the tongue


Supplement

In most mammals, including humans, the hyoid apparatus is shaped like a horseshoe. However, in humans, some of the bones of the hyoid apparatus are fused into a single bone called os hyoideum. In other animals such as frogs, the hyoid apparatus has a hyoid body that is chiefly comprised of hyaline cartilage and two pairs of processes (i.e. alary process and the posteriolateral process).


Word origin: from the Greek word hyoeides meaning "shaped like the letter upsilon" (υ)
