What is heart muscle tissue?
heart muscle tissue is a highly specialized type of muscle found only in the walls of the heart. This type of muscle has a number of unique qualities that make it possible to download regularly to force the heart to defeat. At the microscopic level, it has some different features that facilitate identification and allow the examiner to distinguish it from other types of muscles. The body also includes voluntary or skeletal muscles that connect with the skeleton to allow it to articulate and move, along with an involuntary or smooth muscle, such as those found in the bowels. Both types of muscle respond to nerve signals. People can voluntarily start the skeletal muscle movements, but the smooth muscle is not under conscious control. Like skeletal muscles, it has a striped appearance and cells can have more than one core. As with smooth muscle tissue, heart muscle tissue under voluntary control. Unlike both other types of muscles, the entry from the nerves is not necessary to stimulate muscle contractions. Contraction of heart svAle tissues are mediated by specialized pacemaker cells.
Looking under the microscope, the highly branched appearance of this tissue becomes visible. In addition, signs known as intercaled discs can be seen where individual muscle cells are connected. These discs make it easy to communicate rapidly, allowing the heart to coordinate muscle contractions. This type of muscle tissue is also designed for very high endurance and should not be tired like other muscles.
The heart muscle is known to be extremely hard, which is due to the requirements of this type of tissue. The connected network of muscle cell chains makes the heart resistant and very robust. While the heart rhythm in the chest may feel a relatively weak someone is not in stress or elaboration, the heart is in fact a very active organ, as can be seen in videos of hearts involving.
Historically believed that heart tissue withThe ramparts were unable to restore, like many other types of tissues. Since then, research has shown that he is actually doing it, but very slowly. Starting around 20 years, approximately one percent of the heart muscle tissue is replaced each year. Understanding the internal functioning of this type of muscle tissue is important for people who are interested in heart conditions such as cardiomyopathy.
