Changes in metabolism, hormonal fluctuations, lower activity levels and other issues can all contribute to an expanded waistline, which, aside from aesthetic concerns, can lead to conditions like Type 2 diabetes, high blood pressure and heart disease. But before taking action, it's important to know how our weight actually affects us and what we can really do about it. Too many of us in midlife and beyond may believe some myths about fat and weight that researchers have long since debunked. 1. What, then, accounts for the sometimes flabbier appearance of our arms as we age? So don't cease your workouts because you fear you're just building up future fat; a decline in muscle mass is inevitable, but the benefits of exercise are especially valuable as we age to maintain overall health and ward off frailty by keeping bones strong. 2. 3. 4. 5. 6. 7.
10 Stubborn Body Myths That Just Won't Die, Debunked by Science. HowStuffWorks "Top 10 Brain Myths" At one time in history, decapitation was one of the preferred methods of execution, in part thanks to the guillotine.
Although many countries that execute criminals have dispatched with the method, it's still performed by certain governments, terrorists and others. There's nothing more final than the severing of one's head. The guillotine came about because of the desire for a quick, relatively humane death. But how quick is it? If your head were cut off, would you still be able to see or otherwise move it, even for just a few seconds? This concept perhaps first appeared during the French Revolution, the very time period in which the guillotine was created. Another often-told tale of demonstrated consciousness following beheading dates to 1905. Mind & Body. Body + Human Body. Head and neck anatomy. Head and neck anatomy focuses on the structures of the head and neck of the human body, including the brain, bones, muscles, blood vessels, nerves, glands, nose, mouth, teeth, tongue, and throat.
It is an area frequently studied in depth by surgeons, dentists, dental technicians, and speech language pathologists. Musculoskeletal system Body proportions. While there is significant variation in anatomical proportions between people, there are many references to body proportions that are intended to be canonical, either in art, measurement, or medicine.
Similarly, in art, body proportions are the study of relation of human or animal body parts to each other and to the whole. These ratios are used in veristic depictions of the figure, and also become part of an aesthetic canon within a culture. Basics of human proportions Human proportions marked out in an illustration from a 20th century anatomy text-book. Life Lists. Gray's Anatomy of the Human Body. Neutral spine.

Stomach. In most vertebrates, the stomach is located between the esophagus and the small intestine.
It secretes protein-digesting enzymes called proteases and strong acids to aid in food digestion, (sent to it via esophageal peristalsis) through smooth muscular contortions (called segmentation) before sending partially digested food (chyme) to the small intestines. Human stomach 3D Human Anatomy. Human leg. Legs are used for standing, walking, jumping, running, kicking, and similar activities, and constitute a significant portion of a person's mass.
Structure In human anatomical terms, the leg is the part of the lower extremity that lies between the knee and the ankle, the thigh is between the hip and knee and the term "lower extremity" is used to describe the colloquial leg.

Google's Body Browser is a Google Earth for Human Physiology. Google has mapped just about every traffic artery you could ever want to locate on Google Maps, but what if the thruway you're looking for isn't on any road atlas?
To help you tell your axillary artery from your common carotid, Google has created a G-Maps-like search-able guide for the human body that lets you zoom, scroll, and search for every muscle, gland, nerve, bone, or organ in our common physiology. As far as handy Web apps go, Body Browser is pretty neat; a sliding scroll bar allows you to peel away layers of the body, starting at the skin and moving down through the muscles and bone/organs to the cardiovascular and nervous systems. It allows you to zoom in tight (with nice resolution) to get the name of a specific bodily bit. Clicking on anything produces a handy label that identifies what you're looking at.
Then there's the search function of course, which allows you to locate any part of the body by just typing in the name. [Google Operating System Blog] Human physical appearance.

Physiological differences Humans are distributed across the globe with exception of Antarctica, and form a very variable species.
Eye color. In humans, the pigmentation of the iris varies from light brown to black, depending on the concentration of melanin in the iris pigment epithelium (located on the back of the iris), the melanin content within the iris stroma (located at the front of the iris), and the cellular density of the stroma. The appearance of blue and green, as well as hazel eyes, results from the Rayleigh scattering of light in the stroma, a phenomenon similar to that which accounts for the blueness of the sky. Neither blue nor green pigments are ever present in the human iris or ocular fluid. Eye color is thus an instance of structural color and varies depending on the lighting conditions, especially for lighter-colored eyes. Genetic determination Eye color is an inherited trait influenced by more than one gene. These genes are sought using associations to small changes in the genes themselves and in neighboring genes. These changes are known as single-nucleotide polymorphisms or SNPs.
Amber. Human eye. The human eye is an organ that reacts to light and has several purposes. As a sense organ, the mammalian eye allows vision. Rod and cone cells in the retina allow conscious light perception and vision including color differentiation and the perception of depth. Naked Guide to Life and Death ... Puberty Boy.

Male anatomy. Body. Body -Knowledge. Skeletal muscle. Skeletal muscle is a form of striated muscle tissue which is under the control of the somatic nervous system; that is to say, it is voluntarily controlled. It is one of three major muscle types, the others being cardiac and smooth muscle. As their name suggests, most skeletal muscles are attached to bones by bundles of collagen fibers known as tendons. Discovery Health "How Your Heart Works" Human anatomy. Sleep -Knowledge. Male Body. Human Anatomy. Body. Blood pressure. Blood pressure without further specification usually refers to the systemic arterial pressure measured at a person's upper arm and is a measure of the pressure in the brachial artery, the major artery in the upper arm. A person’s blood pressure is usually expressed in terms of the systolic pressure over diastolic pressure and is measured in millimetres of mercury (mm Hg), for example 120/80.
It is also expressed as the amount over normal atmospheric pressure (760 mm Hg), so a blood pressure of 120 mm Hg would actually be 880 mm Hg of true pressure. Blood pressure varies in healthy people and animals, but its variation is under control by the nervous and endocrine systems. Blood pressure that is pathologically low is called hypotension, and that which is pathologically high is hypertension. Both have many causes and can range from mild to severe.

Muscle. Muscle tissues are derived from the mesodermal layer of embryonic germ cells in a process known as myogenesis. There are three types of muscle, skeletal or striated, cardiac, and smooth. Muscle action can be classified as being either voluntary or involuntary. Cardiac and smooth muscles contract without conscious thought and are termed involuntary, whereas the skeletal muscles contract upon command.  Skeletal muscles in turn can be divided into fast and slow twitch fibers. The Care Online:- Source for your personal health care online. Weight Loss Toronto - Weight Loss Information.
