Cytoplasmic continuity
WebFeb 1, 2003 · Their cytoplasm consists of a giant, multinucleated tissue, the trabecular syncytium, which is connected via open and plugged cytoplasmic bridges to cells such as archaeocytes, choanoblasts, and cells with spherical inclusions. Because all of the sponge is cytoplasmically interconnected, electrical signals can propagate through the animal.

Did you know?
WebNerve cells are connected by sites of contact and not cytoplasmic continuity. Waldeyer himself was neutral on this point, and strictly speaking the neuron doctrine does not depend upon this element. The heart is an example of excitable tissue where the cells connect via cytoplasmic continuity and yet is perfectly consistent with cell theory. WebContinuity of cytoplasm from cell to cell is maintained through cytoplasmic …
WebMar 1, 2024 · contact sites at each end, allowing cytoplasmic continuity (Fig 1); however, few studies have successfully demonstrated this feature. Interestingly, a subset of TNTs described as “close-ended” protru-sions facilitate electrical coupling between cells through GJs at the tip of the protrusion and recipient cell (Wang et al, 2010; Wang WebTo overcome this, plants have evolved channels called plasmodesmata that provide cytoplasmic continuity between each cell and its immediate neighbors. We first review plasmodesmata basics-their architecture, their origin, the types of cargo they transport, and their molecular components.
WebApr 22, 2008 · In adult plants, plasmodesmata-mediated cytoplasmic continuity is highest in young organs and minimal in more mature tissues. Thus, plasmodesmata connectivity is critical during organ formation, … WebCytoplasmic continuity between adjacent spermatids is lost during this process. Main …

As a result the neuron doctrine has multiple elements, each of which were the subject of low level theories, debate, and primary data collection.
