Question at position 34 asks: What are the main parts of a neuron, other than the cell body?
Option A: 'Dendrites and glia' — Dendrites are indeed neuronal processes that receive signals, but glia are supportive cells, not a primary structural component of the neuron itself. So this pairing misstates what constitutes the main parts of a neuron beyond the cell body.
Option B: 'Axon and dendrites' — This is correct in the sense that neurons have two major extending processes aside from the soma: the dendrites (which receive input) and the axon (which transmits output). It encompasses the primary structural components that extend from the cell body.
Option C: 'Axon and glia' — While the axon is a key neuronal process, glia are not considered core parts of the neuron itself; they are separate supportive cells in the nervous system. This option confuses neuron structure with neighboring glial tissue.
Option D: 'Glia and mitochondria' — Glia, as mentioned, are supportive cells, not neuron main parts. Mitochondria are organelles within neurons, not considered as the primary structural parts that extend from the cell body. This option mixes cellular components with the macro-structural parts of the neuron itself.
In summary, the only choice that correctly identifies the main neuronal processes aside from the cell body is the combination of axon and dendrites, whereas the others either replace or add non-primary components (glia, mitochondria) that do not meet the question's framing of the main parts beyond the soma.
