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.
Related to efferent fibers: Afferent fibers. those fibers conveying impulses to effector tissues (smooth, cardiac, or striated muscle, or glands) in the periphery; those fibers exiting a specific cell group (that is, efferent fibers of the basilar pons), used in reference to a cell group.
