Hyoid bone occurs in which of the following parts?
(a) Sternum
(b) Skull
(a) Ribs
(d) Pectoral girdle

Answer 1

Hint: The hyoid bone also known as tongue bone is the only bone present in the anterior neck besides the cervical vertebrae. It helps the tongue and larynx to stay in place. That's why it is also known as lingual or tongue bone.

Complete step by step answer:
The hyoid bone occurs in the skull. It is the single bond present at the base of the buccal cavity. It is also called a tongue or lingual bone as it gives support to the tongue and larynx. the tongue sits above the hyoid and the larynx hangs below it. it is connected to the neck by muscular attachments.
So, the correct answer is ‘Skull’.

Additional Information: Aside from the cervical vertebrae, the hyoid is the only bone present in the anterior neck. It is not articulated to other bones and connects to other bones only by muscular and ligamentous connectives. It is U in shape and has a central body with two small and two large protruding structures on the superior surface and from the body respectively.
The hyoid is attached to the anterior region of the neck by muscular attachments. These attachments are of two types-suprahyoid and infrahyoid muscles. Besides the muscular attachments, there are one membranous and two ligamentous attachments as well.
Together with the attached muscles, the hyoid bond holds up the tongue and larynx. The tongue sits above it whereas the larynx hangs below. It also helps the muscles to open the jaw.

Note: The hyoid bone is a part of the skull as it is present in the neck. It is also called tongue bone because of the fact that it holds up the tongue and the tongue sits on it. It has key roles in functions like breathing and swallowing and speech.
