The botanist, Matthias Schleiden, found that every structural part of plants was composed of cells. The structure of animal tissues was still not understood until Theodor Schwann, a biologist, concluded in 1839 that cells were the basic unit of animal tissues as well.Characteristics. Cardiac muscle tissue, also known as myocardium, is a structurally and functionally unique subtype of muscle tissue located in the heart, that actually has characteristics from both skeletal and muscle tissues. It is capable of strong, continuous, and rhythmic contractions that are automatically generated.CELL STRUCTURE BIOCHEMISTRY. Schwann cells wrap around and myelinate the neurons found in peripheral nerves. - Schwann cells also play a crucial role in the healing and regeneration of damaged neurons. Satellite cells surround the cell bodies of peripheral neurons, providing insulation and a stable chemical environment.

In injured cardiac tissue, this strategy directs transdifferentiation of resident non-myocyte cells (NMCs) into mature functional cardiac cells that help to restore the native tissue. Over the years, developments in reprogramming methods have suggested that regulation of several intrinsic factors in NMCs can help to achieve in situ direct cardiac …

The myofibrils of cardiac muscle are very similar in structure, function, and appearance to ­those of skeletal muscle. FIGURE 3.3 Microscopic structure of myocytes. Each myofibril is composed of smaller functional units called sarcomeres that are oriented end to end along the myofibril. The sarcomere is the basic contractile unit of the myocyte.

The myocyte network, coupled by gap junctions, is generally believed to be electrically isolated from fibroblasts in vivo. In culture, however, the heterogeneous cell types form functional gap junctions, which can provide a substrate for electrical coupling of distant myocytes, interconnected by fibroblasts only.An organelle (think of it as a cell's internal organ) is a membrane bound structure found within a cell.

An action potential (AP) is a voltage change that propagates along the membrane of a myocyte ( muscle cell) or other cells such as a nerve cell. The AP is generated by the movement of positively charged ions, mainly Na+ and K+, across the plasma membrane. This generates an electrical current that travels down the length of the myocyte. what's swot analysis 1. Introduction.
