SQUAMOSAL Meaning and
Definition
-
Squamosal is an adjective that is primarily used in the field of anatomy and zoology. In anatomy, it refers to a specific bone found in the skull of certain vertebrates, including humans. The squamosal bone is located on the side of the skull, forming part of the temporal bone region. It is positioned between the parietal bone and the temporal bone, and it contributes to the structure and protection of the ear.
In terms of its zoological application, squamosal is used to describe an external feature found in certain reptiles and, more commonly, in reptile-like creatures of the past, such as dinosaurs. The term refers to a triangularly shaped scale or plate that is positioned on the side of the head, overlapping with other scales or plates. The squamosal plays a role in protecting the head and neck region in these animals.
The term squamosal is derived from Latin origins, with "squama" meaning "scale" and "-osus" signifying "full of" or "abounding in." Its usage extends beyond its dictionary definition, as it is an important anatomical term when studying the skeletal structures of both modern and ancient animals.
