Question

What muscle cells branch?

Answer 1

Hint: Muscle cells make up the muscle tissues, which are called myocytes. Cardiac, skeletal and smooth are the types of muscle cells in the human body. Cardiac and skeletal myocytes are long and fibrous. Smooth muscle cells. Muscle cells provide the special ability to tissues, for shortening or contracting for the production of movement of body parts. The tissues are highly cellular and well supplied with blood vessels.

Complete answer:
Cardiac muscle cells branch usually. They are striated and involuntary muscles present in the myocardium. They are made up of cells known as cardiomyocytes and mainly, they consist of only one nucleus. Though striated, they differ from skeletal muscles in that they are highly branched with cells connected through overlapping projections of sarcolemma known as intercalated discs.
Cardiac myocytes are narrow, short, and rectangular. They consist of organelles like skeletal muscle cells and sarcomeres, which provide needed energy for contraction. The intercalated discs possess gap junctions, which are utilized for communication and diffusion. They permit the transmission of contractile force between cells, as electrical propagation propagates from one cell to another. This facilitates a uniform contracting force. The satellite cells are responsible for the replacement of damaged ones as cardiac cells cannot divide.
The intercalated discs appear as dark bands between cells, which is a unique characteristic of cardiomyocytes.

Note:
The key role of cardiomyocytes is to beat the heart effectively by generating enough contractile force. The cells contract together in unison, which causes enough pressure for forcing blood around the body. They are 0.1 millimeter long and 0.02 millimeter wide. The dark bands are formed from membranes of adjacent myocytes being very close together, forming a kind of glue between cells.
