The term "squama frontalis" refers to the bony scale that covers the forehead of some animals, such as reptiles or birds. The pronunciation of this term is /ˈskweɪ.mə frʌnˈteɪ.lɪs/, where "squama" is pronounced as /ˈskweɪ.mə/ and "frontalis" as /frʌnˈteɪ.lɪs/. The phonetic transcription shows that "squama" has a stress on the first syllable, while "frontalis" is stressed on the second syllable. The spelling of this term follows the Latin origin, with "squama" meaning "scale" and "frontalis" referring to the forehead.
Squama frontalis is a term used in anatomy to refer to a specific anatomical structure located on the frontal bone of the human skull. The term is derived from Latin, where "squama" means "scale" or "plate" and "frontalis" refers to the frontal bone.
The squama frontalis is the smooth, rounded, and flattened portion of the frontal bone that forms the forehead. It is situated above the orbits (eye sockets) and below the hairline. This region is generally arched and convex, providing protection to the underlying frontal lobes of the brain.
The squama frontalis possesses various anatomical landmarks and features. These include the glabella, which is a small bony prominence located just above the root of the nose, and the supraciliary arches, which are bony ridges extending horizontally above the orbits. The squama frontalis also exhibits certain irregularities like frontal eminences, which are rounded elevations on the forehead, that differ in prominence between individuals.
The squama frontalis is an important anatomical landmark in craniofacial assessment and forensic anthropology. Its shape, size, and irregularities can provide valuable information for identifying skeletal remains and assist in reconstructing an individual's facial features. Additionally, it plays a crucial role in reconstructive surgery and plastic surgery procedures, where the contour and structure of the squama frontalis are carefully considered to achieve desired aesthetic outcomes.

The term "squama frontalis" is primarily formed by the combination of two Latin words: "squama" and "frontalis".
1. Squama: The word "squama" comes from the Latin term "squāma", which refers to a scale or a flake. It can be traced back to the Proto-Indo-European root "*sk(h)eu-", meaning "to cover" or "to hide". Over time, "squama" developed more specific meanings related to scales or flakes, often in reference to fish scales.
2. Frontalis: The term "frontalis" is derived from the Latin word "frōntālis", which originates from "frōns" meaning "forehead" or "brow". It typically describes something related to the forehead or front part of the head.
