The human body contains many cells A which are very long and branched, and look like electric wires. The longest branch of this cell is B whereas there are many small branches C. Any two A cells do not join to one another completely in the human body. There is a microscopic gap D between every pair of adjacent A cells, through which electric impulses can pass by the release of a chemical substance.

What is the name of (i) branch B, and (ii) branches C?
