1·Cells in the secretory portion and duct have different electrophysiological phenomena. At normal condition, resting membrane potential of secretory cells was obviously higher than that of duct cells.

汗腺导管细胞和分泌细胞具有不同的电生理现象，正常状态下分泌细胞静息膜电位明显高于导管细胞。

2·The typical secretory granules of the A-cells could also be found in the cells between the ductile and acinar cells in the exocrine portion.

分泌颗粒较少，导管上皮细胞间、腺细胞间及间质内有的细胞含有类似于A细胞的分泌颗粒。
