Axons are usually surrounded by a fatty substance called myelin. Myelin allows action potentials to propagate quickly from one neuron to another, allowing for rapid signal transmission. It is a critical part of the nervous system and it's absence has devastating effects, as seen in conditions such as multiple sclerosis.
Researchers have found that patients with low levels of folate in their blood are more likely to develop hearing loss (Gok 2004; Lasisi 2010; Gopinath 2010), and that low vitamin B12 levels are associated with hearing loss (Gok 2004) and tinnitus (Shemesh 1993).
Vitamins E and K. Pine nuts provide generous amounts of the essential vitamins E and K. Both of these nutrients have an effect on your cardiovascular system -- vitamin K allows you to form clots to prevent bleeding after injury, while vitamin E helps you produce red blood cells essential for oxygen transport.itamins E and K.
