Cardiac and skeletal muscles share a similar inner construction/structure that contains fibers with alternating thick and thin elements, called _____________, which gives them the ability to contract.

Respuesta :

Both skeletal and cardiac muscles are striated muscles made up of repeating units called sarcomeres that are crossed on a regular basis by tiny red and white lines, giving the muscles their recognizable striated look and their names.

What connects skeletal muscle to cardiac muscle?

Cardiac muscle is a striated muscle like skeletal muscle, and the two muscle types' mechanisms of contraction are mostly identical. This is why cardiac muscle is similar to other muscle types. Both require actin and myosin, which are arranged in a highly structured lattice as the foundation of the force-generating mechanism.

Heart muscle is striated like skeletal muscle, but unlike skeletal muscle, it cannot be controlled voluntarily, earning it the name involuntary muscle. It is branching, has one nucleus per cell, and can be identified by the presence of intercalated disks.
