Brain Atlas - Introduction The central nervous system (CNS) consists of the brain and the spinal cord, immersed in the cerebrospinal fluid (CSF). Weighing about 3 pounds (1.4 kilograms), the brain consists of three main structures: the cerebrum, the cerebellum and the brainstem. Cerebrum - divided into two hemispheres (left and right), each consists of four lobes (frontal, parietal, occipital and temporal). The outer layer of the brain is known as the cerebral cortex or the ‘grey matter’. – closely packed neuron cell bodies form the grey matter of the brain. Cerebellum – responsible for psychomotor function, the cerebellum co-ordinates sensory input from the inner ear and the muscles to provide accurate control of position and movement. Brainstem – found at the base of the brain, it forms the link between the cerebral cortex, white matter and the spinal cord. Other important areas in the brain include the basal ganglia, thalamus, hypothalamus, ventricles, limbic system, and the reticular activating system. Neurons
Clinical Knowledge Summaries - Home PT Education: The First Month with a New Client A New Direction Hi Team, as I promised in my first post for the year, 2010 at me-dot-com will see the introduction of some different types of articles. Today’s post is the first ever article (published on this site) written specifically for Personal Trainers (PTs), PT students, PT managers, centre managers and health club owners. Having personally completed over 40,000 PT sessions since 1987, I consider myself to have reasonable insight into what does and doesn’t work (on a range of levels) when it comes to the product and service of Personal Training. My centre in Brighton is a 10,000 square foot dedicated Personal Training Brighton facility: no members, no general training, no casual workouts, no contracts, no pressure sales and no queues for machines. When I began my PT career there was no blueprint to follow, no other PTs to learn from and no ‘How-to-PT’ guide. Back in the day (when I lived on the gym floor) my clients trained with me for an average of about three years. 1. 3. 4.
The Ultimate Guide To Dropsets: How To Use the Best High Intensity Techniques Of All Time I started bodybuilding nearly twenty years ago, and during that time, I’ve had the opportunity to experiment with literally dozens, if not hundreds of high intensity training methods. These include supersets, giant sets, pre-exhaustion, negatives, partials, static holds, continuous tension, peak contraction, 5 sets of 5, 8 sets of 8 and 21′s just to name a few. If I were only allowed to pick one high intensity technique for building muscle, that technique would be drop sets. What Are Drops Sets And Who Invented Them? A drop set is the simple technique where you perform a set of any exercise to failure or just short of failure, then drop some weight and continue for more repetitions with the reduced poundage. Why Do Bodybuilders Love Drop Sets? Bodybuilders are unique among athletes because they’re concerned purely with cosmetic improvements and not athletic performance. However, if pure mass is what you’re after, then drop sets are ideal! Creative Drop Set Methods #5 | Wide Drop Sets 1. 2.
Master Muscle List Home Page Master Muscle List Home Page Your Lungs & Respiratory System Listen Time for Talk Your lungs are important for breathing . . . and also for talking! Above the trachea (windpipe) is the larynx (say: LAIR-inks), which is sometimes called the voice box. Across the voice box are two tiny ridges called vocal cords, which open and close to make sounds. When you exhale air from the lungs, it comes through the trachea and larynx and reaches the vocal cords. The amount of air you blow out from your lungs determines how loud a sound will be and how long you can make the sound. Experiment with different sounds and the air it takes to make them — when you giggle, you let out your breath in short bits, but when you burp, you let swallowed air in your stomach out in one long one! Love Your Lungs Your lungs are amazing. Keeping your lungs looking and feeling healthy is a smart idea, and the best way to keep your lungs pink and healthy is not to smoke. You can also show your love for your lungs by exercising!
Whey vs. Soy -- You've Been Tricked Source: Elite Fitness: Online Bodybuilding Magazine If you remember many years ago, weight gainers were the big thing and protein powders were out! Then, in like a storm came the "low calorie" weight gainers (yeah right!) and the criticism of the high calorie diet. Right after this came the inundation of whey protein. Most supplement companies do not really care what the truth about supplements really is -- they will promote what is "hot". In this issue of Elite Fitness News, we'll take a close look at whey protein and how it compares to other proteins -- soy protein in particular. BV vs PDCAAS BV (Biological Value) vs PDCAAS (Protein Digestibility Corrected Amino Acid Score). I guarantee that after reading this newsletter, you'll never look at proteins the same way again. If you read any of the bodybuilding magazines for the last few years now, it is hard not to notice the concerted effort that the publishers have made to push whey protein as bodybuilding's superior protein source. 1.
