Pronunciation: [manjˈuːbɹi͡ə] (IPA) 
Manubria is a plural form of manubrium, which means the upper part of the sternum bone. The spelling of the word "Manubria" is in line with its Latin origin, where the "u" makes a long "oo" sound, and "b" is pronounced like "b," not "bi." The IPA phonetic transcription of the word would be /məˈnuːbriə/, where the primary stress is on the second syllable ("-nu-"), and the secondary stress is on the fourth syllable ("-bri-").
Manubria refers to the plural form of the noun "manubrium," which is derived from the Latin word "manubrium" meaning "handle" or "handle of a sword." In anatomy, manubria specifically refers to certain bone structures found in the human body.
The manubria are particularly seen in two main areas: the sternum and the malleus, one of the three small bones in the middle ear.
In the sternum, the manubria commonly refers to the sternal manubrium or simply the manubrium sterni. It is the uppermost part of the sternum, a flat bone located in the middle of the chest. The manubrium sterni is broader and wider compared to the rest of the sternum, which gives it a handle-like appearance. It articulates with the clavicles (collarbones) and the first pair of ribs, playing an important role in the stability and function of the chest.
In the malleus or hammer bone, the manubria are part of the tiny hammer-shaped bone located in the middle ear, along with the incus (anvil) and stapes (stirrup). The manubria or manubrial process of the malleus is a handle-like structure that attaches to the eardrum (tympanic membrane) on one end and articulates with the incus on the other. It transmits sound vibrations from the eardrum to the inner ear, enabling the process of hearing.
Overall, manubria are significant anatomical structures found in both the sternum and the middle ear, contributing to the proper functioning of the chest and the hearing mechanism.
The word "manubria" has its origins in the Latin language. It is the plural form of the Latin word "manubrium", which means "handle" or "haft". The word "manubrium" itself is derived from the Latin verb "manus" meaning "hand" and the suffix "-brium" denoting object or instrument. In anatomical terminology, "manubria" refers to certain parts of bones that resemble handles, such as the handle-like projection on the sternum (breastbone), or the handle-shaped portion of malleus (a small bone in the inner ear).
