The vagus nerve is part of the group of cranial nerves responsible for innervation of structures derived from the branchial arches. It is also part of a group together with the glossopharyngeal and accessory nerves that passes through the jugular foramen which is termed the vagus group.ranial nerves are those nerves which arise from the brain and brain stem rather than the spinal cord. Nerves arising from the spinal cord are the peripheral nerves. There are 12 pairs of cranial nerves and these pairs of nerves passage through foramina in the skull, either individually or in groups.
Popular Answers. 1  Yes, there is a relation between the pH and the electrical current flow [the conductivity] of a solution, but there are other factors that affect the conductivity. This topic, the conductivity of solutions, takes up a full chapter in a textbook on physical chemistry with many graphs and numerical tables.
Each material's thermal conductivity is determined by a constant, Î», calculated as: Î» = (Q x L) / (A x t x Î T) where Q is heat, L is the thickness of the surface, A is the surface area, t is time, and ÎT is the difference in temperature. A material's thermal conductivity is a fundamental property. Those materials with high thermal conductivity will transfer heat rapidly, either by receiving heat from a hotter material or by giving heat to a colder material. On the contrary, materials with low thermal conductivity act as thermal insulators, preventing the transfer of heat.
