What are the upper jawbones commonly called?

• A. Mastoid
• B. Zygoma
• C. Mandible
• D. Maxillae

Answer: (D)

The upper jawbones are commonly referred to as the maxillae. These bones form the upper part of the jaw and hold the upper teeth in place, as well as contributing to the structure of the face, including the cheeks, nasal cavity, and orbits. The maxillae are essential for various functions, such as eating and speaking, as they support the alignment and function of the upper teeth and form part of the palate. The other terms mentioned refer to different structures: the mastoid refers to a part of the temporal bone located behind the ear, contributing to the middle ear's structure; the zygoma, also known as the cheekbone, forms the prominence of the cheeks and contributes to the orbit; and the mandible is the lower jawbone, which holds the lower teeth and is movable, allowing for chewing and speaking. Understanding these distinctions is crucial for a solid foundation in anatomy related to emergency medical services.
