Cells of the nervous system

Cells of the nervous system
Types of Neurons (Nerve Cells) The human body is made up of trillions of cells. Cells of the nervous system, called nerve cells or neurons, are specialized to carry "messages" through an electrochemical process. Neurons come in many different shapes and sizes. Neurons are similar to other cells in the body because: Neurons are surrounded by a cell membrane.Neurons have a nucleus that contains genes.Neurons contain cytoplasm, mitochondria and other organelles.Neurons carry out basic cellular processes such as protein synthesis and energy production. However, neurons differ from other cells in the body because: Neurons have specialize cell parts called dendrites and axons. The Neuron One way to classify neurons is by the number of extensions that extend from the neuron's cell body (soma). Bipolar neurons have two processes extending from the cell body (examples: retinal cells, olfactory epithelium cells). Pseudounipolar cells (example: dorsal root ganglion cells). What is inside of a neuron?

Bloomin' Brains Summer Camp - Sowing the Seeds of Neuroscience 2016 Bloomin' Brains Summer Camp was held from August 1 to August 5, 2016. Camp applications for summer 2017 will be available early next year. Are you a middle school student interested in a summer "deep dive" into neuroscience and botany? Spend a week in at UW working with scientists, teachers, and specialists to explore, experiment, and discover! Conduct hands-on science experimentsLearn about uses of medicinal plants in Native cultures Explore the structure and function of the brainEnjoy field trips to the Burke Museum, Botany Greenhouse, Medicinal Herb Garden, the Hyde Herbarium, and UW FarmListen to real scientists talk about their careersDiscover "the art of the brain" by constructing modelsMake a plant extract and tie-dye a shirt Discover how much fun science can be! This is a free summer camp funded by an NIH grant examining effective science education.

Next Generation Science Standards - Activity LIsting In this activity, students analyze the production and utilization of organic molecules in ecosystems. Students construct a food web for Yellowstone National Park, including producers, primary consumers, secondary consumers, decomposers, and trophic omnivores. Then, students analyze a trophic cascade that resulted when wolves were re-introduced to Yellowstone. Students learn how organic molecules move and are transformed in ecosystems as a result of the trophic relationships in food webs, photosynthesis, cellular respiration, and biosynthesis. This provides the basis for understanding carbon cycles and energy flow through ecosystems. In the final section, students use these concepts and quantitative reasoning to understand trophic pyramids.

The Earth Has Lungs. Watch Them Breathe. – Phenomena: Curiously Krulwich What a difference a leaf makes! Well, not one leaf. We have 3.1 trillion trees on our planet—that’s 422 trees per person. If we count all the leaves on all those trees and take a look at what they do collectively to the air around us, the effect—and I do not exaggerate—is stunning. It tracks the flow of carbon dioxide across the planet over 12 months, starting in January. Here’s the thing about trees … We know they absorb air. Come winter, the leaves fall off, trees go bare. The Difference June Makes That’s the month when trillions upon trillions of leaves are opening, growing, and starting to breathe, and what you will see in the video is their collective breath literally cleaning the sky. When leaves fall, the situation reverses … and it feels a little scary. Consider the fantastic scale of this global dance. Now imagine how many leaves might be on all those trees. I think of them more like lungs, often with squeezable openings. … There are so, so many of them! So consider: Help! Related

Curriculum and Experiments | feed.nourish.thrive Bringing Biotechnology to Life "Bringing Biotechnology to Life" is a resource for science educators and others interested in earning more about biotechnology and its role in food production. This unit of instruction addresses national learning standards for 7th – 10th grade, yet the interest level may be much broader. Seven sequential lessons guide the learner through the process of understanding DNA, selective breeding over time, agricultural biotechnology today, including foods produced through biotechnology(often referred to by consumers as genetically modified organisms (“GMOs”).Students are also presented with tools to evaluate the reliability of information they see and hear. Lesson 1: What is DNA? The objective of lesson 1 is for students to be able to identify the primary components in a DNA structure and describe the ole of DNA in trait inheritance.

Exploring Prairies Intro "Try to envision what Iowa must have been like more than 150 years ago. It's early morning, a low-hanging veil of fog drifts silently over the top of a sea of grasses. The early morning sunrise casts its warm glow on colorful, fragrant flowers as far as the eye and mind can envision. Bobolinks and meadowlarks greet the early morning glow with their wondrous songs. ~ Gary Tonhouse A prairie is a tract of land characterized predominantly by grasses. The tallgrass prairie was located in heartland of the continental United States. Prairies vary in the types of vegetation they support. The big bluestem dominated the Iowa prairie, particularly in the east where abundant rainfall provided rich moist soil. The prairie was home to numerous animal species including insects, birds, mammals and reptiles that adapted to the seasonal climatic changes.
