COSTOCORACOID Meaning and
Definition
-
Costocoracoid is a term commonly used in anatomy and zoology to describe a specific structure found in the skeletal system of certain animals. Specifically, it refers to a small bone that is typically located in the shoulder region, connecting the rib cage or sternum with the coracoid process, a bony prominence on the scapula or shoulder blade.
In avian anatomy, the costocoracoid bone is a key component of the pectoral girdle, or the skeletal framework supporting the wings. It provides attachment sites for several muscles involved in wing movement and stability, including the pectoralis muscle responsible for flapping the wings. Additionally, it acts as a supportive link between the ribcage and the coracoid process, aiding in the transmission of forces during flight.
The presence of a costocoracoid bone is a characteristic feature of birds and certain reptiles. This bone contributes to the strength and efficiency of wing motion, allowing for sustained flight. Notably, some extinct animals like pterosaurs, which were ancient flying reptiles, also possessed a similar structure.
Understanding the presence and function of the costocoracoid bone is essential in studying the biomechanics and locomotion patterns of flying animals. Its role in facilitating flight serves an integral part of the natural history and evolutionary adaptations of species with aerial capabilities.

Etymology of COSTOCORACOID
The word "costocoracoid" is derived from a combination of two anatomical terms, "costo-" and "coracoid".
1. "Costo-" is a prefix derived from the Latin word "costa", which means "rib". It is commonly used in medical terminology to refer to anything related to the ribs. For example, "costal" describes something pertaining to the ribs.
2. "Coracoid" is derived from the Greek word "korakoeidḗs" (κορακοειδής), which means "resembling a crow". It is composed of "korax" (κόραξ) meaning "crow" and the suffix "-oeidēs" (-οειδής) meaning "resembling".
