fmaxille

fmaxille is a term that refers to the upper jawbone in vertebrates. It is also known as the maxilla. This bone is a paired structure that fuses during development to form a single unit in the midline of the face. The fmaxille is a complex bone that plays a crucial role in several functions.

The fmaxille forms the upper part of the oral cavity, holding the upper teeth. It also contributes to the formation of the floor of the orbit, which houses the eye, and the lateral wall of the nasal cavity. The bone articulates with several other skull bones, including the frontal, ethmoid, nasal, lacrimal, zygomatic, palatine, and inferior nasal concha bones, forming the facial skeleton.

Anatomically, the fmaxille has a pyramidal shape with a body and four processes: the alveolar process, which supports the teeth; the palatine process, which forms the anterior part of the hard palate; the zygomatic process, which articulates with the zygomatic bone (cheekbone); and the frontal process, which articulates with the frontal bone.

In humans, the fmaxille houses the maxillary sinuses, which are air-filled cavities within the bone. These sinuses are connected to the nasal cavity and play a role in humidifying inhaled air and resonating the voice. Disruptions or infections of the fmaxille can impact chewing, speech, breathing, and facial aesthetics.
