Cell Size and Scale Some cells are visible to the unaided eye The smallest objects that the unaided human eye can see are about 0.1 mm long. That means that under the right conditions, you might be able to see an ameoba proteus, a human egg, and a paramecium without using magnification. 100 Incredible Lectures from the World’s Top Scientists Posted on Thursday June 18, 2009 by Staff Writers By Sarah Russel Unless you’re enrolled at one of the best online colleges or are an elite member of the science and engineering inner circle, you’re probably left out of most of the exciting research explored by the world’s greatest scientists. Nervous System: Explore the Nerves with Interactive Anatomy Pictures [Continued from above] . . . conditions inside and outside of the body and send this information to the CNS. Efferent nerves in the PNS carry signals from the control center to the muscles, glands, and organs to regulate their functions. Nervous TissueThe majority of the nervous system is tissue made up of two classes of cells: neurons and neuroglia. Neurons. Neurons, also known as nerve cells, communicate within the body by transmitting electrochemical signals.

Halloween Sunday School Lessons Halloween is a day in our country when both the young and old find fun in death and what is scary. Many children set out to find the scariest costume to wear for their school parade and trick-or-treating. With so many visual symbols of death set before our children at this time of year it is fitting to teach them about how children of God have no need to fear death. This lesson walks children through a passage from the book of Matthew to help them see how death is not a scary thing for the believer. It could be used in Sunday School, but would be ideal for a Halloween Children’s Church lesson. We’ve also posted an alternative lesson plan for Halloween – Faith Overcomes Fear!

General Issues in Scaling « PreviousHomeNext » S.S. Stevens came up with what I think is the simplest and most straightforward definition of scaling. He said: Primitive Brain Is 'Smarter' Than We Think, MIT Study Shows Primitive structures deep within the brain may have a far greater role in our high-level everyday thinking processes than previously believed, report researchers at the MIT Picower Center for Learning and Memory in the Feb. 24 issue of Nature. The results of this study led by Earl K. Miller, associate director of the Picower Center at MIT, have implications about how we learn. The new knowledge also may lead to better understanding and treatment for autism and schizophrenia, which could result from an imbalance between primitive and more advanced brain systems. Our brains have evolved a fast, reliable way to learn rules such as "stop at red" and "go at green." Dogma has it that the "big boss" lobes of the cerebral cortex, responsible for daily and long-term decision-making, learn the rules first and then transfer the knowledge to the more primitive, large forebrain region known as the basal ganglia, buried under the cortex.
