Insulin oscillation the oscillations become synchronized by electrical coupling between closely located beta cells that are connected by gap junctions, and the periodicity is more uniform (3-6 min). Pulsatile insulin release from the entire pancreas requires that secretion is synchronized between 1 million islets within a 25 cm long organ. Much like the cardiac pacemaker, the pancreas is connected to cranial nerve 10, and others, but the oscillations are accomplished by intrapancreatic neurons and do not require neural input from the brain. It is not entirely clear which neural factors account for this synchronization but ATP as well as the gasses NO
Insulin resistance wall, especially elsewhere on the body, such as hips or thighs), hypertension, hyperglycemia, and dyslipidemia involving elevated triglycerides, small dense low-density lipoprotein (sdLDL) particles, and decreased HDL cholesterol levels. With respect to visceral adiposity, a great deal of evidence suggests two strong links with insulin resistance. First, unlike subcutaneous adipose tissue, visceral adipose cells produce significant amounts of proinflammatory cytokines such as tumor necrosis factor-alpha (TNF-a), and Interleukins-1 and −6, etc. In numerous experimental models, these proinflammatory cytokines disrupt normal insulin action in fat and muscle cells, and may be a major factor in causing the whole-body insulin resistance observed
