NSC 4330 Exam 1Describe the progression of elements of a simple nervous system beginning with an 'independent effector' as seen in sponges. Discuss the characteristics of each element and the effect/benefit of having each additional element in the system. Specifically cover independent effectors, sensory neurons, motor neurons, interneurons. (Extra points may be awarded for further development: centralization, bilateral symmetry, cephalization, segmentation.) Discuss Santigo Ramon y Cajal...

Characteristics of an Animal - Answer- heterotroph (eat other organisms for food), multicellular (no cell wall, eukaryotic), motility/movement, *neurons/muscle cells (except sponges) Surface Area to Volume Ratio - Answer- limits the size of cells, as surface area increases volume decreases Importance of Surface Area - Answer- determines rate at which nutrients diffuse across a membrane into a cell and rate at which waste products diffuse out of cells Techniques Animals use to Increase S...
