viscerocrâne

Viscerocranium is the anterior part of the skull, housing the organs of the face. It is derived from the skeletal elements of the pharyngeal arches, specifically the mandibular and hyoid arches, and contributes to the formation of the mouth, nose, and orbits. The viscerocranium is composed of numerous bones, including the maxillae, zygomatic bones, nasal bones, lacrimal bones, palatine bones, inferior nasal conchae, vomer, and mandible. These bones articulate with each other and with the neurocranium to form the characteristic shape of the face. The viscerocranium is crucial for functions such as mastication, respiration, olfaction, and visual perception. Its development is a complex process involving the fusion of multiple ossification centers and is influenced by genetic and environmental factors. Variations in the viscerocranium can occur, leading to a wide range of facial features.
