Option C. It articulates with the temporal bone.

Explanation:

HYOID BONE:

Introduction and Osteology:

Hyoid bone is also known as lingual bone or tongue bone.  It is a mobile bone and is unique as it does not articulate (unite, join) with any other bone in the human skeleton.

Hyoid bone is a part of axial skeleton and one of the bones of the neck. It is located in anterior part of the neck. The other bones which consitute the skeleton of neck are: cervical vertebrae, clavicles and manubrium of sternum (brestbone).

It is horseshoe-shaped and consists of a body, two greater horns and two lesser horns.

Body is the middle part of hyoid bone. It faces anteriorly.

Each end of the body is connected to a greater horn which projects posterosuperioly. Near the junction of greater horn and body, a smaller lesser horn projects superoposteriorly from superior surface of body.

LOCATION:

It is located  anterior to vertebral column in the angle between the mandible (jawbone)  and thyroid cartilage (largest cartilage of larynx/voice box) at the level of C3 vertebra.

ATTACHMENTS:

It does not articulate with any other bone in the human body. It is connected to bones only by other muscles or ligaments.

It is suspended by various muscles and ligaments.

Hyoid bone connects with muslces of the mouth and tongue from above, larynx (thyroid cartilage) below and pharynx behind. It is also serves as an attachment site for various anterior neck muscles.

QUESTION:

Coming back to the question, the incorrect statement is asked.

A- it is anterior to the vertebral column.

This is a correct statement as hyoid bone is located anterior to vertebral column in the anterior part of neck at the level of C3 vertebra.

B- It is positioned between mandible and the larynx (voice box)

This is also a correct statement as Hyoid bone is located between mandible (jawbone) and larynx (voice box).

C- It articulates with the temporal bone.

This is an incorrect statement and is the answer of the question as we are asked to pick out the incorrect statement.

Hyoid bone does not articulate with any bone in the skeleton. It articulates with other bones only via other muscles or ligaments.

D- It serves as an attachment point for some muscles of tongue.

This is a correct statement. Hyoid bone is connected to various tongue muscles. Another name for hyoid bone is lingual bone or tongue bone.

E- it serves as an attachment point for some muscles of neck and pharynx.

This is a correct statemt as hyoid bone provides attachments to some mucles of neck and pharynx. Functionally, hyoid bone helps in swallowing and keeping the airway patent (open).

cuz some people don't have enough food. that's why we need more ppl to donate food to the hungry.
