Insulin core is hydrophobic but its periphery has hydrophillic regions
Taste impulses are from a region in the brain called the primary gustatory cortex. The sense of taste is ultimately felt on various areas of the tongue where taste buds are present.
What is the links the cerebellum and medulla to higher cortical areas
it might be the vena cava
Blood is the liquid that flows through humans veins and keeps them alive. The blood carries oxygen to vital areas and also carries carbon dioxide away from the tissues.
The "impulses" to skeletal muscles come primarily from alpha motor neurons in the ventral horn of the spinal cord. These neurons release acetylcholine on the muscles, which causes sodium to enter the muscle, leading to contraction. The alpha motor neurons themselves get input from several sources, such as the primary motor area in the cerebral cortex of the brain. However, even this brain area gets input from other brain areas, including sensory areas. In a certain sense, the impulses to the muscles "originate" from the environment in the form of sensory signals.
No, the endoplasmic reticulum just carries things from the nucleus of Golgi bodies to areas where they are needed.
J. Friedmann (1966) maintained that the world can be divided into four types of region. Beyond the cores are the upward transition regions-areas of growth spread over small centers rather than at a core. Development corridors are upward transition zones which link two core cities such as Belo Horizonte and Rio de Janeiro. The resource-frontier regions are peripheral zones of new settlement as in the Amazon Basin. The downward transition regions are areas which are now declining because of exhaustion of resources or because of industrial change. Many 'problem' regions of Europe are of this type. This concept may be extended to continents. The capital-rich countries of Germany and France attract labor from peripheral countries like Spain, Greece, Turkey, and Algeria. Higher wages and prices are found at the core while the lack of employment in the periphery keeps wages low there. The result may well be a balance of payments crisis at the periphery, or the necessity of increased exports from the periphery to pay for imports. In either case, development of the periphery is retarded.
Clean areas in a surgical environment are the areas between the shoulders and the waist. Dirty areas would be all areas above the shoulders and below the waist.
