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.
Where R is resistance in ohms, L is the length of the wire in meters, A is the cross sectional area of the wire in square meters, and Ï is the electrical resistivity in ohm-meters. Electrical conductivity is the inverse of resistivity: itâs the ability of a material to let current pass through.
