Blood vessel formation occurs via vasculogenesis and angiogenesis. Vasculogenesis is the process of de novo blood vessel formation, and angiogenesis is the process whereby endothelial cells sprout from pre-existing vessels.
WebTwo basic aspects of the evolution of the nervous system must be considered: first, how primitive systems serve newer functions, and, second, how the formation of new systems serves newer functional requirements. Early theories on the evolutionary origin of the nervous system argued for a three-stage process: first, the development of non ...
