It aids in skin...
New born human infants have the largest brains among primates, but also the highest proportion of body fat. Before birth, if the supply of nutrients from the mother through the placenta is limited or unbalanced, the developing baby faces a dilemma: should resources be allocated to brain growth, or to fat deposition for use as an energy reserve during the early months after birth? Scientists at the University of Southampton have shown that this decision could have an effect on how fat we...
LiverActive is a spray application liver detox product, recommended for helping to establish and maintain health of the all-important human liver. LiverCleanseDiet.com releases its product review. (PRWEB) August 18, 2012 No liver cleanse product, by itself, should be given sole responsibility for health of the human liver. For those with a genuine interest in purifying their liver, LiverCleanseDiet.com urges positive adaptations in lifestyle, exercise, and nutrition as means of...
"Sound vibrations are transmitted to the inner ear via anterior extensions of the swim bladder or via bony ossicles", the biologist Tanja Schulz-Mirbach explains how swim bladders may serve for hearing. The hearing sensitivity improves considerably in this way. The anterior part of the swim bladder functions in specialized fish species similar to an ear drum. Up to now the effects of the different swim bladder morphologies have not been investigated in detail in cichlid fishes. The...
UCLA researchers say blocking this molecule may improve and speed recovery FINDINGS: Researchers at UCLA have identified a novel molecule in the brain that, after stroke, blocks the formation of new connections between neurons. As a result, it limits the brain's recovery. In a mouse model, the researchers showed that blocking this molecule—called ephrin-A5--induces axonal sprouting, that is, the growth of new connections between the brain's neurons, or cells, and as a result promotes...
Neuroscientists from Wayne State University and the Massachusetts Institute of Technology (MIT) are taking a deeper look into how the brain mechanisms for memory retrieval differ between adults and children. While the memory systems are the same in many ways, the researchers have learned that crucial functions with relevance to learning and education differ. The team's findings were published on July 17, 2012, in the Journal of Neuroscience. According to lead author Noa Ofen, Ph.D.,...
Findings could open avenues for improved therapies for a range of conditions Researchers at McGill University have discovered the cause of an inherited form of epilepsy. The disease, known as double-cortex syndrome, primarily affects females and arises from mutations on a gene located on the X chromosome. Drs. Susanne Bechstedt and Gary Brouhard of the Department of Biology have used a highly advanced microscope to discover how these mutations cause a malformation of the human brain. The...
Fish-saving sound threshold recommended for pile driving projects The rise of ocean infrastructure development to tap energy sources such as tides, offshore wind and natural gas will require more pile driving, the practice of pounding long, hollow steel pipes called piles into the ocean floor to support energy turbines and other structures. But pile driving creates loud, underwater booms that can harm fish and other marine animals. Many scientists and regulators have assumed that...
Using rabies virus, researcher tracks inputs to dopamine neurons A genetically-modified version of the rabies virus is helping scientists at Harvard to trace neural pathways in the brain, a research effort that could one day lead to treatments for Parkinson's disease and addiction. As described in a paper published on June 7 in the journal Neuron, a team of researchers led by Associate Professor of Molecular and Cellular Biology Naoshige Uchida used the virus to create the first-ever...
Changes to just three genetic letters among billions led to evolution and development of the mammalian motor sensory network, and laid the groundwork for the defining characteristics of the human brain, Yale University researchers report. This networks provides the direct synaptic connections between the multi-layered neocortex in the human brain responsible for emotions, perception, and cognition and the neural centers of the brain that make fine motor skills possible. A description of...

The liver is the organ in charge of processing, neutralizing and excreting certain secretions for the metabolic processes. Formation and Orientation The liver is considered to be both the largest internal organ and the largest gland in the human body. It is situated just below the diaphragm, to the right of the stomach and on top of the gallbladder. There are two ways blood can travel to and from the liver: the hepatic artery and the portal vein. The hepatic artery carries blood solely...
The esophagus is the muscular tube that is located between the pharynx and the stomach that aids in digestion during swallowing. Formation and Orientation The esophagus is composed of four separate layers; the mucosa, submucosa, muscularis externa and the adventitia. The mucosa includes the stratified squamous epithelium, lamina propria and muscularis mucosae. The submucosa houses the esophageal glands and connective papillae. The muscularis externa is composed of three sublayers The...
The ovaries are the two reproductive female organs where the eggs are produced. These are parallel to the testes in men. Formation and Orientation Each ovary is the size of an almond and is located on one side of the pelvis before the ureter and internal iliac artery but after the external iliac artery. They are attached to either side of the uterus. They are connected and release eggs to fallopian tubes, though not attached, monthly during the menstrual cycle. They also produce...
Skin is the outermost organ that protects and incases the tendons, ligaments, bones, muscles, etc. It is also the largest organ of the human body. Formation and Orientation Healthy skin consists of vitamins A, C, D and E, but in all skin, there are melanocytes which produce mesodermal cells. These cells allow for the absorption of UV rays. There are five main pigments that provide color in the skin’s many levels. Although not found in the skin, Oxyhemoglobin is found in the blood,...
The appendix is a dead-end tube like structure, ranging from 2 to 20 cm, that spans off the cecum of the colon. It is attached to the lower part of the large intestine. Formation and Orientation The appendix can be found in many mammals including marsupials, euarchontoglires (rodents) as wells as humans of course. It is also an organ that forms in the embryotic stage during pregnancy. McBurney’s Point, the point that is one-third the distance from infront and above the spinal cord...
