What are the three different types of muscles in the human body? List of the difference between three muscle cell types. What are the special features of cardiomyocytes?
17 sie 2023 · The cardiac conduction system is a network of specialized cardiac muscle cells that initiate and transmit the electrical impulses responsible for the coordinated contractions of each cardiac cycle. These special cells are able to generate an action potential on their own (self-excitation) and pass it on to other nearby cells (conduction ...
24 kwi 2023 · The cardiac conduction system is a collection of nodes and specialised conduction cells that initiate and co-ordinate contraction of the heart muscle. It consists of: Sinoatrial node. Atrioventricular node. Atrioventricular bundle (bundle of His) Purkinje fibres.
24 wrz 2020 · Alyssa Tomlinson. Scientists have mapped and described the function of cells in six regions of the adult heart, providing a new foundation for studying heart disease. In these beating human heart cells, scientists have highlighted a protein important in muscle contraction (green).
3 lis 2023 · Overview of the anatomy and functions of the heart. Heart (right lateral view) The heart is a muscular organ that pumps blood around the body by circulating it through the circulatory/vascular system. It is found in the middle mediastinum, wrapped in a two-layered serous sac called the pericardium.
