PROSTERNUM Meaning and
Definition
-
Prosternum refers to a bony or cartilaginous structure found in the chest region of animals, particularly vertebrates. It is specifically located in the front part of the thorax, below the neck, and above the abdomen. The term "prosternum" is derived from the Latin words "pro," which means "before" or "in front," and "sternum," which refers to the breastbone.
In vertebrates, such as birds, reptiles, and some mammals, the prosternum is an important anatomical structure that serves as an attachment point for various muscles, ligaments, and tendons. It provides support and stability to the chest, aiding in movement and maintaining the body's structural integrity. The prosternum plays a crucial role in facilitating the movements of wings in birds and the limbs in other animals.
The shape and size of the prosternum can vary among different species, reflecting their specific adaptations and lifestyle. For example, in birds, it is usually a flat, plate-like structure that forms a prominent sternum or "keel," which enables the attachment of flight muscles. In quadrupeds like mammals, the prosternum may be less distinct, with a more subtle prominence and different attachments for locomotion-related muscles.
Understanding the anatomy and function of the prosternum is essential for researchers and anatomists studying animal physiology, biomechanics, or evolutionary biology. By analyzing the prosternum's characteristics and variations across species, scientists can gain insights into the adaptations and evolutionary relationships among different groups of animals.

Etymology of PROSTERNUM
The word "Prosternum" is derived from the combination of the Latin words "pro" meaning "before" or "in front of" and "sternum" meaning "breastbone". In anatomy, the sternum refers to the long, flat bone located in the center of the chest, to which the ribs are attached. The term "Prosternum" is used in zoology to describe the anterior part of the sternum in insects, particularly referring to the ventral region of the thorax.
