The secretory cells of the salivary glands of the snail, Helisoma trivolvis, exhibit regenerative, overshooting action potentials whose ampliture may exceed 100 mV. The salivary glands consist of paired, tubular, epithelial structures with acinar outpocketings. The secretory cells display extensive electrical coupling which allows action potentials to(More)
The neural regulation of an exocrine gland was investigated at the level of identified effector neurones. The salivary gland neuroeffector system of Helisoma consists of a pair of acinous glands innervated by two symmetrically located, identified buccal ganglion neurones (4R and 4L). Neurones 4R and 4L usually are electrically coupled and display(More)
