The Brain I. Supporting structures Anatomy of the Brain 3 Major Areas: Cerebrum-consists of two hemispheres (thalamus and hypothalamus) that are incompletely separated by the great longitudinal fissure 4 Lobes: Frontal-major functions are concentration‚ abstract thought‚ information storage or memory‚ and motor function. It also contains Broca’s area‚ critical for motor control of speech Parietal-analyzes sensory information and relays the interpretation of the info to the thalamus. It

that of bacteria and manufacturing many of their own proteins. The fact that both the organelles reproduce by binary fission can also be mentioned. Besides the similarities between the two organelles‚ notable differences are present in their structure and function that could be stated as follows: Chloroplasts and mitochondria both have number of different membranes where most of the energy conversion reactions take place. But there are some membranes in the chloroplast that contain some crucial components

Method Participants The participants consisted of 4 patients who had undergone surgery 3-5 years prior-to the experiment due to severe seizures. Participants ranged from 37 to 63 years of age‚ and a mean age of 51 years (SD = 10.24). Design This natural case study design included Independent variables (a) the visual field‚ and (b) the hand of the participant. These were measured by the participant’s intellectual processing of information. The Dependent variables (a) the participants ability

Chapter 3 Cell Structure and Function Section 3.1: Cell Theory: Cells are the smallest building unit of living organisms that can carry out all processes required for life. Almost all cells are too small to see without the aid of a Microscope. Although glass lenses used to magnify images for hundreds of years‚ they were not enough to reveal individual cells. The invention of Compound microscope was in the late 1500s by the Dutch eyeglass maker Zacharias Janssen. In 1665‚ the English scientist

Chapter 2 Integrin Structure and Function Manakan Betsy Srichai and Roy Zent Abstract Integrins are a large family of heterodimeric glycoprotein receptors first discovered over twenty years ago. They exist as two noncovalently bound a- and b- subunits that function as adhesion molecules and play key roles in many biological processes including actin cytoskeleton organization and transduction of intracellular signals regulating cellular functions. Integrins bind a variety of extracellular matrices

The Five Major Structures of the Human Brain University of Phoenix PSY 240 October 27‚ 2012 Olivia Fransis The human brain is nothing short of incredible. In a way it’s the world’s most powerful computer because it can process tasks at lightning speeds and simultaneously be in control of our reflexes and every other voluntary and involuntary functions. It is the most important and complex organ as well as our core for learning At the point of birth‚ the brain weighs an average of

The structure and function of carbohydrates A carbohydrate is an organic molecule containing only Carbon‚ Hydrogen and Oxygen with the general formula Cn(H20)n. They are made up of individual molecules called monomers which are joined together by condensation reactions to make a longer chain called a polymer. Carbohydrates are categorised in to three main groups; monosaccharides‚ disaccharides and polysaccharides. Monosaccharides are single sugars and are sweet tasting soluble substances such

Cell structure and function Cell structures come in various shapes and sizes dependent on their location within an organism and what life sustaining process it carries out. These can range from the globular protein of a red blood cell‚ designed to carry four oxygen molecules at a time to the tail like flagellum of a bacteria designed for mobility and penetration of organs within a body. There are tow major types of cells‚ prokaryotic cells and eukaryotic cells. An organelle is defined as an
