The sarcolemma is composed of a lipid bilayer, which contains hydrophilic heads and hydrophobic tails.Cells are the structural and organizational unit of life. 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. Through this experience, I gained insight into the fundamental tenets of cell theory, which postulates that all living organisms consist of cells, cells serve as the fundamental …Structure. Smooth Muscle cell (myocyte) The shape of smooth muscle is fusiform, which is round in the center and tapering at each end (3-10 µm thick and 20-200 µm long).

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. In 1972, Wyllie, Kerr, and Currie coined the term apoptosis to describe a form of cell death with morphological characteristics that are distinct from necrosis ( 1). Necrosis is a passive form of cell death that results from acute cellular injury, which causes cells to swell and lyse. In contrast, apoptosis is an active process in which cells ...Apply cell theory. Observe different samples using a microscope and determine whether the organisms are unicellular or multicellular. Each principle of cell theory will be introduced, to help you learn the differences between prokaryotes and eukaryotes.
