Question

name these structures associated with sympathetic neuroeffector junctions. ganglion varicosities preganglionic fiber postganglionic fiber i dont know yet

Explanation:

Sympathetic neuroeffector junctions involve postganglionic fibers. These fibers release neurotransmitters from varicosities (bulbous swellings) to communicate with effector cells. Ganglion is a cluster of neuron cell bodies. Preganglionic fibers are the first - stage neurons in the autonomic nervous system. Since the structure in question is part of the post - ganglionic communication (as shown in the varicosity - containing segment which is a feature of postganglionic fiber terminals in sympathetic neuroeffector junctions), we can identify it.

Answer:

Postganglionic fiber
