The term "varicosities" refers to the enlarged areas in the branching network of the neuroeffector synapse of a postganglionic sympathetic neuron. This term is commonly used in the field of neuroscience to describe the specialized structures found at the axonal endings of sympathetic neurons. The varicosities contain neurotransmitters that are released into the synaptic cleft to interact with receptors on the target cells, leading to various physiological responses. Therefore, option C is the correct answer.
