Question
From the list given, select all possible items that are true with respect to the sympathetic subdivision of the peripheral autonomic nervous system.
Question options:
Contain single-fiber pathways that bring information from the CNS to effectors.
Contain efferent pathways that bring information to skeletal muscle fibers.
Contain efferent dual-fiber pathways that exit the CNS in the thoraco-lumbar regions.
Contain efferent dual-fiber pathways comprised of short pre-ganglionic fibers that synapse with long post-ganglionic fibers, the latter of which synapse with effectors.
Contain efferent aceytlcholine-secreting pre-ganglionic fibers that can either stimulate or inhibit post-ganglionic fibers, depending upon what type of acetylcholine receptor is present on the dendrites/cell bodies of the post-ganglionic cell.
Contain pre- and post-ganglionic fibers recognizable as efferent fibers because of the true, anatomic dendrites that project directly from the cell bodies of these neurons.
Contain efferent pathways whose post-ganglionic fibers secrete norepinephrin (NE) that, once released, always has a stimulatory effect on the effector cells.
