The Human Body & Anatomy. 7 Big Myths About Body Fat. SPECIAL FROM Next Avenue By Linda Melone After age 50, maintaining a healthy weight can be even more challenging than it was in earlier years.
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. 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? Mind & Body. Body + Human Body. Head and neck anatomy. An MRI scan of the head.
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. Life Lists. Gray's Anatomy of the Human Body. Neutral spine. Posture and natural curvatures The word posture comes from the Latin verb ponere, which means "to put or place.
" The general concept of human posture refers to "the carriage of the body as a whole, the attitude of the body, or the position of the limbs (the arms and legs). "  Webster's New World Medical Dictionary defines neutral posture as the stance that is attained "when the joints are not bent and the spine is aligned and not twisted. Neutral posture has given rise to the idea of achieving “ideal posture.” Ideal posture indicates proper alignment of the body’s segments such that the least amount of energy is required to maintain a desired position. The benefit of achieving this ideal position would be that the least amount of stress is placed on the body’s tissues. In this position, a person is able to completely and optimally attain balance and proportion of his or her body mass and framework, based on his or her physical limitations.
Sole (foot) The sole is the bottom of the foot.
In humans the sole of the foot is anatomically referred to as the plantar aspect. The equivalent surface in ungulates is the hoof. Deep anatomy of the sole The skin on the sole of the foot lacks the vellus hair and pigmentation found on the rest of the body, and has a high concentration of sweat pores.

Stomach. 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. Structure 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. This article generally follows the common usage. Comparison between human and gorilla skeletons. (Gorilla in non-natural stretched posture.) Human body. 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.
Human physical appearance. The human body Factors affecting physical appearance Various factors are considered relevant in relation to the physical appearance of humans. Physiological differences Humans are distributed across the globe with exception of Antarctica, and form a very variable species. In adults, average weight varies from around 40 kilos for the smallest and most lightly built tropical people to around 80 kilos for the heavier northern peoples. Size also varies between the sexes, the sexual dimorphism in humans being more pronounced that that of chimpanzees, but less that the dimorphism found in gorillas. The colouration of skin, hair and eyes also varies considerably, with darker pigmentation domination in tropical climates and lighter in polar regions.
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. Human eye. The human eye is an organ that reacts to light and has several purposes. As a conscious 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.
