Chapter 2: Neurons and Glia 1. Introduction * Although there are many neurons in the human brain (about 100 billion)‚ glia outnumbers neurons by tenfold. 1:10 ratio. * Neurons are the most important cells for the unique functions of the brain. * Neurons sense changes in the environment‚ communicate these changes to other neurons‚ and command the body’s responses to these situations. * Glia‚ or glial cells‚ are thought to contribute to brain function mainly by insulating‚

usable energy. The human body does through the mitochondria. The mitochondria is an organelle used to create energy for the human body. It was described first by Richard Altmann in 1890 ("Mitochondria."). Altman described the mitochondria as a rod shaped organelle found in most cells ("Mitochondria."). The mitochondria is a very complex organelle made up of many different parts. It is a double membrane organelle that consists of an inner and an outer membrane ("Structure of Mitochondria." ). There

Explain their role in hydrogen peroxide metabolism. Peroxisomes are single membraned organelles that contain the enzyme catalase‚ which is responsible for the breakdown of hydrogen peroxide. Eukaryotic cells typically have peroxisomes present in the cell‚ however they are most commonly found in the “kidney and liver

cells do not. This is examined as a major difference between the two; therefore‚ under the microscope both cells appear much unique from one another. The animal cells examined appear as empty circles or ovals surrounded by a thin membrane. There are organelles

The majority of the organelles were able to receive the nutrient in the 1 cm cell and almost all of them in the 0.5 cm cell. This is caused due to the larger surface area to volume ratio as the cell size depends on the efficiency of the material to flow in and out through diffusion. Through diffusion‚ the organelles in the cell receive all the vitally needed nutrients to survive. If there is a big surface area to volume

1. Nuc stand for nucleus. The nucleus controls and helps regulate most of the actions that take place within the cell. Flag stands for the flagella. The flagella extend from the plasma membrane and help the cell move through liquid. ER stand for the endoplasmic reticulum. There are two different types of endoplasmic reticulum in each cell; the smooth and rough endoplasmic reticulum. They both have separate functions; the smooth endoplasmic reticulum processes lipids‚ and the rough endoplasmic reticulum
