Intercalated discs or lines of Eberth are microscopic identifying features of cardiac muscle. Cardiac muscle consists of individual heart muscle cells (cardiomyocytes) connected by intercalated discs to work as a single functional syncytium. By contrast, skeletal muscle consists of multinucleated muscle fibers and exhibits no intercalated discs ...
The first world record in the women's discus throw was recognized by the International Association of Athletics Federations in 1923. As of 2013, 55 world records have been ratified by the IAAF in the event.

The discus throw (pronunciation ⓘ), also known as disc throw, is a track and field sport in which the participant athlete throws an oblate spheroid weight — called a discus — in an attempt to mark a farther distance than other competitors. It is an ancient sport, as demonstrated by the fifth-century-BC Myron statue Discobolus.
Intercalated discs are part of the cardiac muscle cell sarcolemma and they contain gap junctions and desmosomes. The cardiac syncytium is a network of cardiomyocytes connected by intercalated discs that enable the rapid transmission of electrical impulses through the network, enabling the syncytium to act in a coordinated contraction of the ...
Details of intercalated discs. Cardiomyocytes, are considerably shorter and have smaller diameters than skeletal myocytes. Cardiac muscle (like skeletal muscle) is characterized by striations – the stripes of dark and light bands resulting from the organised arrangement of myofilaments and myofibrils in the sarcomere along the length of the cell.
men. v. t. e. Video on YouTube Official Video @1:02:14. The women's discus throw was an event at the 1956 Summer Olympics in Melbourne, Australia. The qualification round mark was set at 42.00 metres. Nine competitors failed to reach that distance. [1]
A muscle cell, also known as a myocyte, is a mature contractile cell in the muscle of an animal. [1] In humans and other vertebrates there are three types: skeletal, smooth, and cardiac (cardiomyocytes). [2] A skeletal muscle cell is long and threadlike with many nuclei and is called a muscle fiber. [3] Muscle cells develop from embryonic ...
