Like smooth muscle, cardiac muscle also works involuntarily. It is a very thick muscle that is found only in the walls of the heart. Its job is to pump blood out of the heart and into blood vessels called arteries(动脉). The arteries help carry the blood to all part...
Which is the biggest muscle in the human body? The gluteus maximusis the largest muscle in the human body. It is large and powerful because it has the job of keeping the trunk of the body in an erect posture. It is the chief antigravity muscle that aids in walking up stairs. ...

The human body has hundreds of muscles. The three types are skeletal muscles, smooth muscles and cardiac, or heart muscles. Each kind of muscle has a special job to do. The skeletal muscles are attached to the bones; they actually hold the skeleton toget
In cardiomyocytes, dystrophin exerts the same functions as in skeletal muscle cells; therefore, a lack of dystrophin results in increased cardiomyocyte structural vulnerability, membrane instability, disruption in Ca2+homeostasis, augmented reactive oxygen species (ROS) production, and mitochondrial dysfunction...
Human body simulating method for examining cardiac muscle, involves conditioning body by adiabatic rapid exposure of radio frequency impulses for simulating body in presence of impulses of gradient of field orientationThe method involves subjecting a body to be examined in a continuous magnetic field. ...
The cardiomyocyte-derived GFP+ EVs were also positive for intravesicular troponin I (cTnI) and muscle-associated glycogen phosphorylase (PYGM). This is the first direct demonstration that cardiomyocyte-derived EVs are present in the circulation and that the increased number of cardiac-derived EVs in ...
Learn about cardiac muscle tissue and its unique structure, function, and role in the heart's blood pumping and electric signal transmission.
For the heart to pump throughout the body,cardiac musclein the myocardium has to be excited and contract uniformly. This is facilitated by a cardiacaction potentialthat is due to a change in the voltage or membrane potential in the plasma membrane of cardiac myocytes. When this occurs, ions ...
In a group of previously hospitalized patients, persistent symptoms were reported in 72%, with dyspnea featuring as the most prevalent symptom (54.8 %)14. Other investigators found non-cardiac symptoms, including fatigue, muscle weakness and sleep difficulties, more prevalent after 6 months, ...
