In the Microscopy lab, you will examine a chicken intestine slide that is specially prepared for a transmission electron microscope. A myocyte (also known as a muscle cell) is the type of cell found in some types of muscle tissue. Myocytes develop from myoblasts to form muscles in a process known as myogenesis.

All of the organisms, except the algae are multicellular eukaryotes. This means that they are composed of more than one cell and have one important organelle in common. Some tissue samples, such as the fox epithelia, have this large internal organelle stained and very clearly visible. Learning Objectives. Cardiac muscle tissue is only found in the heart. Highly coordinated contractions of cardiac muscle pump blood into the vessels of the circulatory system. Similar to skeletal muscle, cardiac muscle is striated and organized into sarcomeres, possessing the same banding organization as skeletal muscle ( [link] ).The myocardium is highly organized tissue, composed of several cell types that include smooth muscle cells, fibroblasts, and cardiac myocytes. The fundamental contractile cell of the myocardium is the myocyte. The purpose of this review is to examine the structural components of the myocyte and then to place these components into a functional context with respect to the contractile process.

During early human development, myocyte and connective tissue cell numbers increase at a similar rate, from about 0.5 × 10 9 at 28 weeks of foetal development to 2–3 × 10 9 several weeks post partum. Thereafter, myocyte cell numbers remain stable, while the connective tissue cell count rises with cardiac weight to ∼7 × 10 9 at 2 months ...

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 ...Jan 17, 2023 · Myocyte Structure. Myocytes can be incredibly large, with diameters of up to 100 micrometers and lengths of up to 30 centimeters. The sarcoplasm is rich with glycogen and myoglobin, which store the glucose and oxygen required for energy generation, and is almost completely filled with myofibrils, the long fibers composed of myofilaments that facilitate muscle contraction.
