What does syncytial mean in biology?
(sin-SIH-shee-um) A large cell-like structure formed by the joining together of two or more cells. The plural is syncytia.
What is syncytial cell?
Syncytia are evolutionarily conserved cellular structures form by the multiple cell fusions of uninuclear cells. In mammals, the best example of physiological syncytia is muscle fibers, which contain thousands of fused muscle cells to allows their rapid coordinated contraction [7].
What is syncytium in physiology?
A syncytium is a single cell that contains multiple nuclei. In humans, syncytia can be found in the skeletal muscles. These muscles are made up of fibers, which are long syncytia.
What is the function of syncytium?
Bone Cell Communication Through Gap Junctions Bone cells form a functional syncytium in which gap junction channels allow the direct intercellular communication of small molecules between cells.
What is a syncytium quizlet?
Syncytium – A group of cells that function as a unit. Cardiac muscle tissue in the atria and ventricles form a syncytium, meaning that individual cells within the heart really function as a unit. Intercalated Discs.
What is syncytium Class 11?
Hint: A syncytium, also called a symplasm, is a multinucleate cell (having more than one nucleus in a cell). This condition is reached when multiple mononuclear cells (many cells having one nucleus) fuse together. Syncytium can also be defined as formation of a giant cell produced by fusion of two or more cells.
What is syncytium and Coenocytic?
Syncytium is a multinucleated cell that is formed due to cell aggregation followed by the dissolution of the cell membranes while coenocyte is a multinucleated cell formed due to multiple nuclear divisions without undergoing cytokinesis. Thus, this serves as the key difference between syncytium and coenocyte.
What is syncytial epidermis?
Syncytial epidermis (multilayered epidermis) is found in the body wall of Ascaris. Syncytium is a multinucleate cell that is formed from multiple nuclear divisions without their accompanying cytokinesis. The vital feature of parasitic Platyhelminthes is Syncytial Epidermis.
What does syncytial mean medical term?
Medical Definition of syncytial. : of, relating to, or constituting syncytium syncytial tissue.
What is the syncytial theory of development?
Syncytial Theory. The syncytial theory of neural development was proposed by Victor Hensen in 1864 to explain the growth and differentiation of the nervous system. This theory has since been discredited, although it held a significant following at the turn of the twentieth century.
What is the function of the syncytium?
Function of syncytium. The syncytium functions as a transporting epithelium (Sibley et al., 2005), a barrier to both maternal cells and pathogens, and an endocrine cell, producing large quantities of steroids, CG, CS, placental growth hormone, leptin, and soluble VEGF receptor and many other secretory substances (Evain-Brion and Malassine, 2003).
Syncytial Epidermis comprises cells with a large number of nuclei. When many cells are fused Syncytial Epidermis are formed. The original nuclei of the syncytial epidermis degenerate when the first series of epidermal cell bodies, developed immediately below and having the characteristics of protein-synthesizing cells, become connected with it.
