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.
The efferent nerve fiber is the axon of a motor neuron. Bundles of these axons form a motor nerve, or efferent nerve. In the nervous system there is a closed loop system of sensation, decision, and reactions. This process is carried out through the activity of sensory neurons, interneurons, and motor neurons.
