Interstitium. The interstitium is a contiguous fluid-filled space existing between a structural barrier, such as a cell membrane or the skin, and internal structures, such as organs, including muscles and the circulatory system. [1][2] The fluid in this space is called interstitial fluid, comprises water and solutes, and drains into the lymph ...
Basic cellular compartments. Cellular compartments in cell biology comprise all of the closed parts within the cytosol of a eukaryotic cell, usually surrounded by a single or double lipid layer membrane. These compartments are often, but not always, defined as membrane-bound organelles. The formation of cellular compartments is called ...
It is perhaps the easiest to understand TDI devices by contrast with more well-known types of CCD sensors. The best known is the staring array one. In it, there are hundreds or thousands of adjacent rows of specially engineered semiconductor which react to light by accumulating charge, and slightly separated in depth from it by insulation, a tightly spaced array of gate electrodes, whose ...
That’s why the discovery of what some scientists call a previously unrecognized organ is so fascinating. In a new study, researchers claim that interstitium -- fluid-filled spaces in tissue that ...
The intermembrane space (IMS) is the space occurring between or involving two or more membranes. [1] In cell biology, it is most commonly described as the region between the inner membrane and the outer membrane of a mitochondrion or a chloroplast. It also refers to the space between the inner and outer nuclear membranes of the nuclear envelope ...
The human body and even its individual body fluids may be conceptually divided into various fluid compartments, which, although not literally anatomic compartments, do represent a real division in terms of how portions of the body's water, solutes, and suspended elements are segregated. The two main fluid compartments are the intracellular and ...
The inner membrane of mitochondria is similar in lipid composition to the membrane of bacteria. This phenomenon can be explained by the endosymbiont hypothesis of the origin of mitochondria as prokaryotes internalized by a eukaryotic host cell. In pig heart mitochondria, phosphatidylethanolamine makes up the majority of the inner mitochondrial ...
In the mitochondrion, the matrix is the space within the inner membrane. The word "matrix" stems from the fact that this space is viscous, compared to the relatively aqueous cytoplasm. The mitochondrial matrix contains the mitochondrial DNA, ribosomes, soluble enzymes, small organic molecules, nucleotide cofactors, and inorganic ions. [1]
