![]() We found synapses close to the sites of exocytosis, providing morphological evidence for neuronal control of secretion. Asian Leech (aka) The Buffalo Leech or Giant 'Hirudinaria Manillensis'. ![]() Secretion occurs at the very tip of the cell processes, each of which terminates at the proboscis tip at the base of a cuticular pore. The ER provides support for up to several hundred longitudinally oriented microtubules. This originates deeply within the soma and extends through the whole cell process to its terminal. In the process periphery, the vesicles are completely ensheathed by a concentric subplasmalemmal smooth ER cisterna. These contain secretory vesicles through their whole length. Leeches are segmented worms that belong to the phylum Annelida and comprise the subclass Hirudinea. The giant Amazon leech ( Haementeria ghilianii) can grow up to 18 inches and live up to 20 years. 3 min read By Noele Illien ZURICH (Reuters) - Credit Suisse shares slumped by as much as 30 on Wednesday after its largest shareholder said it could not provide further.Changes in membrane potential, membrane current, intracellular sodium, and intracellular pH evoked by aspartate (1 mM), an EAAT agonist, were measured both in the absence and in the. The giant Amazon leech is the world’s largest leech, reaching a length of up to 18 inches That’s one-and-a-half feet long This enormous Amazon leech is reported to reach incredible sizes and spread out to a width of 3.9 inches. The somata taper into long processes extending over several centimeters to the proboscis tip. We have studied possible interactions between these two electrogenic transporters in the giant glial cell of isolated ganglia of the leech Hirudo medicinalis. The rough endoplasmic reticulum (ER) and the Golgi apparatus are organized in the cell periphery, near the highly branched nucleus, and along the lacunae. ![]() Deep plasmalemmal invaginations invade the soma and form an extensive system of extracellular lacunae. The giant somata are densely packed with secretory vesicles. The giant anterior salivary gland cells from the large mammalian blood-sucking, glossiphoniid leech, Haementeria ghilianii, can be subdivided into three morphologically and functionally distinct regions: (1) a soma, responsible for the synthesis and storage of secretory products (2) a long cell process, responsible for the storage and intracellular transport of the secretory vesicles and (3) the site of exocytosis at the process terminal. ![]()
