The cardiac muscle shows many structural and functional features, such as the skeletal and smooth muscles. This cardiac muscle shows cross striation like the skeletal muscle, but they are involuntary and contract automatically like the smooth muscle. You will find the cardiac muscle only in the animal’s heart and some parts of the major vessels tha...
Sometimes you may be asked to identify the cardiac muscle histology slide under a light microscope. I know you already have the basics of important microscopic features of cardiac muscle. Here, I will provide (enlist) the main identification points of the cardiac muscle microscope slide – 1. The sample muscle fibers show the short cylindrical and b...
Before going to the details description of cardiac muscle, you might have the basic knowledge of the skeletal muscle structure (fine or electron microscope). If you want, you may know the histological features of skeletal muscle from the below-mentioned article – 1. The skeletal muscle under a microscope with labeled diagram, So, from the fine stru...
The cardiac muscle is stimulated to contract by a mechanism similar to the skeletal muscle. Here, the contraction is activated by the interaction of actin and myosin microfilaments. A sequential contraction of heart chambers is stimulated by the orderly spread of the action potential through the gap junction (in the intercalated disks). Here, I wil...
First, let’s see the similarities between the cardiac and skeletal muscles under a light microscope. Like the cardiac muscle, skeletal muscle is also made of elongated fibers. You will find numerous myofibrils in these elongated skeletal muscle fibers, like the cardiac fibers. If you see the skeletal muscle under a light microscope, you will find v...
Now, I will show you the cardiac muscle tissue under a microscope-labeled diagram. Here, I will show you both cross and longitudinal sections of the cardiac muscle tissue with the labeled diagram. I tried to show you the longitudinal section of cardiac muscle fibers in the first labeled diagram. Here, the diagram shows the short cylindrical cardiac...
Now, I will show you the cardiac muscle microscope slide figure drawing. You may follow the full drawing tutorial for the cardiac muscle here. Here, I will provide both longitudinal and transverse sectional cardiac muscle drawings. First, let’s see the longitudinal section of cardiac muscle fiber. I tried to draw the short cylindrical muscle fibers...
In this section, I will provide the commonly asked questions on the cardiac muscle under a light microscope with the possible short answer. But, it is recommended to learn all the microscopic features of the cardiac muscle fibers and cells with the labeled diagram from this article (first to end). Okay, now, let’s see the commonly asked questions o...
So, the cardiac muscle under a microscope shows a short cylindrical fiber with a branch. The cardiac muscle fiber is made with cardiac myocytes, which contain centrally located single or multiple nuclei. All the provided labeled diagrams on cardiac muscle under a microscope might provide a clear idea. Now, you can easily identify the cardiac muscle...
Oct 4, 2019 · Cardiac muscle, also known as heart muscle, is the layer of muscle tissue which lies between the endocardium and epicardium. These inner and outer layers of the heart, respectively, surround the cardiac muscle tissue and separate it from the blood and other organs. Cardiac muscle is made from sheets of cardiac muscle cells.
Let’s learn more about the cardiac muscle with the help of a diagram. Diagram of Cardiac Muscle . Cardiac Muscle – Description . The myocardium or cardiac muscle forms the bulk portion of the heart and it is mainly responsible for pumping action. This muscle has several layers of cardiomyocytes or cardiac muscle cells.

Cardiomyocytes are narrower and much shorter in comparison with skeletal muscle cells. Cardiac muscle cells are branched, allowing for faster signal propagation and contraction in three dimensions; Cardiomyocytes closely connect with each other through intercalated discs. Cardiac muscle consists of interlacing bundles of cardiomyocytes.
Nov 23, 2022 · Cardiac muscle fibers are long, branched cells, shaped like cylinders joined end-to-end, with one or two nuclei located centrally. The fibers are separated by collagenous tissue that supports the capillary network of cardiac tissue. The myofilaments of cardiac muscle are arranged in a similar pattern to skeletal muscle, resulting in cross ...

Oct 19, 2024 · Cardiac muscle, in vertebrates, one of three major muscle types, found only in the heart. Cardiac muscle possesses contractile units known as sarcomeres and exhibits rhythmic contractions. The rhythmic contractions are regulated by the sinoatrial node of the heart and thus are not under voluntary control.
