What is the function of somites in the chick embryo?

Somites in the chick embryo are segments of paraxial mesoderm that play a crucial role in the development of the vertebrate body plan. They give rise to the vertebrae, skeletal muscles, and dermis of the skin. Somites also contribute to the organization of the nervous system and the formation of the trunk and limb structures. Additionally, they help establish the segmented nature of the embryo, influencing the patterning of various tissues.
