What are the histological characteristics of cardiac muscle cells?

Muscle: Cardiac Muscle. Cardiac muscle is striated, like skeletal muscle, as the actin and myosin are arranged in sarcomeres, just as in skeletal muscle. Cardiac muscle cells usually have a single (central) nucleus. The cells are often branched, and are tightly connected by specialised junctions.
A.

Which are characteristics of cardiac muscle cells?

Cardiac muscle cells are found only in the heart, and are specialized to pump blood powerfully and efficiently throughout our entire lifetime. Four characteristics define cardiac muscle tissue cells: they are involuntary and intrinsically controlled, striated, branched, and single nucleated.
  • What is the definition of cardiac muscle tissue?

    Cardiac muscle: A type of muscle tissue that is found only in the heart and is distinguishable from the two other forms of muscle, smooth muscle (that moves internal organs, such as the bowels, and vessels, such as the artery walls) and skeletal muscle (that powers joints).
  • Is the heart an involuntary muscle?

    These muscles push materials like food or blood through organs. Unlike skeletal muscle, smooth muscle can never be under your control. Cardiac muscle is also an involuntary muscle, found only in the heart.
  • What is the function of the smooth muscle tissue?

    Each type of muscle tissue in the human body has a unique structure and a specific role. Skeletal muscle moves bones and other structures. Cardiac muscle contracts the heart to pump blood. The smooth muscle tissue that forms organs like the stomach and bladder changes shape to facilitate bodily functions.
B.

What are the properties of cardiac muscle tissue?

Properties of Cardiac Cells. The muscle cells of the heart are unique and responsible for the electrical stimulation that leads to proper mechanical function. Myocardial cells have several different electrophysiologic properties: automaticity, excitability, conductivity, contractility, rhythmicity, and refractoriness.
  • What are the properties of muscle tissue?

    All muscle cells share several properties: contractility, excitability, extensibility, and elasticity: Contractility is the ability of muscle cells to forcefully shorten.
  • What is the definition of cardiac muscle tissue?

    Cardiac muscle: A type of muscle tissue that is found only in the heart and is distinguishable from the two other forms of muscle, smooth muscle (that moves internal organs, such as the bowels, and vessels, such as the artery walls) and skeletal muscle (that powers joints).
  • What is the structure of cardiac muscle cells?

    Although it is striated, cardiac muscle differs from skeletal muscle in that it is highly branched with cells connected by overlapping projections of the sarcolemma called intercalated discs.
