The mandible, in humans, is found near the inferior part of the skull. It facilitates the opening and closing of the jaw, as well as allowing us to chew food. A chicken’s mandible is similar to that of a humans. However, it has increased flexibility and mobility which are more suited to the chicken’s needs. The cranium’s primary function in humans is to protect and house the brain. The cranium of the chicken is similar. However, the there are openings at the base of the cranium and these allow the brain and spinal cord to be directly connected. The maxilla forms the upper jaw in humans. It assists in the formation of certain cavities in the head along with fossae in chickens. In humans, the humerus serves as a insertion and origination point for numerous muscles, such as the pectoralis major and the deltoid. Its primary function is the facilitation of movement and support for the arm . In chickens, the humerus, along with the coracoid and scapula, forms the shoulder. The humerus also joins the radius and ulna to form the elbow. These allow for movement of the arm and are extremely lightweight to allow for flight. In humans, the radius and ulna are two bones located in the superior portion of the arm. They are relatively long and have a curved shape. Along with running parallel to each other, they are also connected to each other at the distal and proximal ends.…
