In this article we will discuss about:- 1. Origin and Development of Cardiac Muscle 2. Histology of Cardiac Muscle 3. Fine Structure 4. Blood Vessels, Lymphatics and Nerves 5. Metabolism. Origin and Development of Cardiac Muscle: Cardiac muscles in the embryo are originated from the mesenchymal tissue. They are formed of the splanchnopleure adjoining the endothelium of the cardiac primordium. [...]
In this article we will discuss about the translocation in humans. Interchanges are the most common structural chromosome changes reported in human. Partial sterility in interchange heterozygotes is infrequent due to the production of balanced gametes and as a result, interchanges in human are identifiable only through the analysis of karyotype, usually coupled with chromosome banding patterns. Various kinds of [...]
