apolar

[Gr. a, priv., and Eng. polar.] Not polar. Anat.: Pertaining to nerve-cells which send out no fibre. Kölliker at first maintained their existence, but afterwards thought they might be unipolar cells, with the i uing fibre in some way hidden from view. "Some writers still insist upon the existence of 'apolar' and 'unipolar' nerve-cells in many parts of the nervous system, although the results of observation positively prove the existence of two fibres in the case of cells which had previously been regarded as unipolar and apolar ."-Beale: Bioplasm (1872), § 243. "See also my paper on the structure of the so-called Apolar, Unipolar, and Bipolar Nerve Cells. Phil ., Trans., 1863."- Ibid ., § 273.
