part_of part of part of anatomical structure morphogenesis developmental process anatomical structure formation involved in morphogenesis Note that, for example, the formation of a pseudopod in an amoeba would not be considered formation involved in morphogenesis because it would not be thought of as the formation of an anatomical structure that was part of the shaping of the amoeba during its development. The formation of an axon from a neuron would be considered the formation of an anatomical structure involved in morphogenesis because it contributes to the creation of the form of the neuron in a developmental sense.
