Myofibril assembly results in a regular array of identical sarcomeres in striated muscle. Sarcomere structure is conserved across the animal kingdom, which implies that the mechanisms of myofibril ...

The human heart, often described as the body's engine, is a remarkable organ that tirelessly beats to keep us alive. At the core of this vital organ, intricate processes occur when it contracts, where ...

Adding to the growing fundamental understanding of the machinery of muscle cells, a group of biophysicists describe -- in minute detail -- how actin filaments are stabilized at one of their ends to ...

This is a preview. Log in through your library . Abstract The variation in thin filament length was investigated in slow and fast muscle from adult and neonatal rats. Soleus (slow) muscle from adult, ...

There are three types of muscle tissue in the human body including cardiac muscle, smooth muscle, and skeletal muscle. Skeletal muscle fibers are those which are attached to the skeleton. They are ...

Scientists have produced the first high-resolution 3D image of the sarcomere, the basic contractile unit of skeletal and heart muscle cells, using electron cryo-tomography (cryo-ET). The international ...

Atrial fibrillation, heart failure and stroke – hypertrophic cardiomyopathy can lead to many serious health conditions and is a major cause of sudden cardiac death in people younger than 35. „The ...
