Webb11 jan. 2012 · CNS axons differ in diameter ( d ) by nearly 100-fold (∼0.1–10 μm); therefore, they differ in cross-sectional area ( d 2) and volume by nearly 10,000-fold. If, as found for optic nerve, mitochondrial volume fraction is constant with axon diameter, energy capacity would rise with axon volume, also as d 2. We asked, given constraints on space … WebbThe regulation of intracellular pH (pH i ) is essential for normal cell function 1 , and controlled changes in pH i may play a central role in cell activation 2 . Sodium-dependent Cl-HCO 3 exchange is the dominant mechanism of pH i regulation in the invertebrate cells examined 3-6 >, and also occurs in mammalian cells7,8.

Webbaxon, also called nerve fibre, portion of a nerve cell ( neuron) that carries nerve impulses away from the cell body. A neuron typically has one axon that connects it with other neurons or with muscle or gland cells. Some axons may be quite long, reaching, for example, from the spinal cord down to a toe. WebbThe internal storage of the ZTE Axon 7 is one of the best ones in the Android market today. It can easily go head to head with storage options of Apple’s iPhone 6 and 6s, with 32GB as the minimum storage option and a 64GB variant. On top of its internal storage is its microSD slot which could accommodate up to 256GB of additional storage. can horses have blue eyes
