Unlike this fission bomb, the hydrogen bomb functions by the fusion, or joining together, of lighter elements into heavier elements. The end product again weighs less than its components, the difference once more appearing as energy.
Report Abuse. Afferent pathways send information to your central nervous system (CNS), or peripheral nervous system (PNS). Efferent pathways send signals from those two locations to your muscles. Taste, sight, hearing, etc. are all afferent pathways. A reflex arc, or simply reflex, is then caused by an afferent pathway signaling to the PNS (Spinal cord), which then immediately signals muscles to react.
1 Afferent fibers are those that carry neural impulses toward the central nervous system. ( 2 Afferent nerves ascend to or approach the central nervous system.). 3  Efferent fibers carry impulses from the central nervous system to effectors such as muscles and glands.
