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 ...

Osaka, Japan - Researchers at Osaka University used electron cryomicroscopy (CryoEM) to image essential cardiac muscle components, known as thin filaments, with unprecedented resolution. They also ...

Before we pinpoint the "arrow's" target, let's establish a foundational understanding of the heart's major components. The ...

The transverse tubules (t-tubules) are invaginations of the cell membrane rich in several ion channels and other proteins devoted to the critical task of excitation-contraction coupling in cardiac ...

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 ...
