Multicellular organisms range from basic to highly complex forms. This engaging program explores the level of organisation necessary for the structure and function of multicellular organisms including cells, tissues, organs and organ systems. It highlights the nervous system of multicellular organisms - both vertebrates and invertebrates - and features excellent dissections of a cane toad and a worm to illustrate the different forms and function of their nervous systems. The footage in the dissecting laboratory is particularly helpful in understanding structure and function of vertebrate and invertebrate nervous systems. This is a practical and information packed program made specifically for the modern classroom.
