The differential paralysis of cardiac nerve endings and muscle

Motor Nerve Endings of Twitch Muscle Fibers in Hippocampus Hudsonius

the differential effects of debate and media analysis as relate to enhancing efl learners critical thinking ability and writing performances

critical thinking ability has an important role in education. accordingly, scholars around the world are searching for new ways for teaching and improving students critical thinking ability. in line with the studies in efl contexts supporting the positive relationship between critical thinking and writing performances, this study investigated the differential effects of halverson’s critical thi...

Ultrastructure of Cardiac Muscle and Nerve Contiguities

FIOURE 1 This electron micrograph shows a nerve process (gr) containing predominantly granular vesicles which makes intimate contact with the surface of a cardiac muscle cell (arrows). A portion of a nerve process (affr) containing only agranular vesicles is situated above the other nerve process. Serial sections would most likely show these two nerve processes lying side-by-side, g, glycogen p...

Biochemistry and ultrastructure of serotonergic nerve endings in the lobster: serotonin and octopamine are contained in different nerve endings.

In this article we report that the distribution of serotonin in the lobster nervous system parallels the distribution of octopamine and that the same tissues that contain endogenous serotonin can synthesize it from tryptophan. Octopamine and serotonin are highly concentrated in a neurosecretory region of the second thoracic roots in association with a group of neurosecretory cells. The roots po...

Nerve Endings With Structural Characteristics

Methods. Serial tangential sections and whole-mount preparations of the scleral spur region of 18 human eyes of different ages were investigated with electronmicroscopic and immunohistochemical methods. For immunohistochemistry antibodies against neurofilament-proteins, synaptophysin, substance P (SP), calcitonin gene-related peptide (CGRP), vasoactive intestinal polypeptide (VIP), neuropeptide...
