Introduction

A group of cells that function together, having a similar structure in the body, is referred to as Tissue. The intercellular matrix, a nonliving object which fills the cell’s gap, contains some special materials, such as salts and fibers. Four major types of tissues found in the body are “epithelial, connective, muscle and nervous”. All tissues have distinctive characteristics due to the presence of salt and fiber. Muscle tissue helps to move body parts.

Muscular Tissue

A group of cells that can move the body parts through shortening or contracting together, is termed muscle tissue. This cellularised cell which is supplied through blood vessels consists of long and slender muscle fibers. This muscle tissue is arranged in a structure through the connective tissue. It comprises contractile proteins, such as actin and myosin. Muscular Tissue can be classified into three major types, such as, “skeletal, smooth, cardiac muscular tissue. 

Skeletal muscle tissue functions with the bones through tendons to allow the body to move accordingly. For this kind of muscular tissue, the animal body functions easily while moving its body parts. On the other hand, the cardiac muscle tissue is connected with the heart, it helps to pump the blood for circulating it throughout the body. This muscle never stops functioning, as it is connected with the layer of animal hearts. Until it gets tired the body remains alive, but after stopping this muscle functioning, body movements stop and the animal dies. 

In order to describe the smooth muscle tissue connected with the layer of intestines, it helps to move the foods to the digestive organ. In addition, it is linked with other organs of the body, such as, “blood vessels, uterus, and bladder”. The cardiac and skeletal muscle tissue combines a number of sarcomeres, which are functioning together, whereas the smooth muscular tissue is not combined with sarcomeres, it works individually. 

Components and functions of Muscular Tissue

The soft tissues that have been found in the animal body, enable the power to move the muscles. The muscle tissue consists of “special contractile proteins and two regulatory proteins and fibers”. The actin and myosin help to contract the muscles and help to move the muscles, similarly, “troponin and tropomyosin” make the muscle relax to move accordingly. The skeletal muscular cells comprise “striation and nuclei”, on the other hand, smooth muscular cells consist of a single “nucleus”. With a striated single nucleus, the cardiac muscular tissue developed. The muscular tissue contains myocytes which contain a number of myofibrils. 

The potential properties of “muscular tissues” are“contractility”, which enhances the ability to shorten the cells forcefully. “Extensibility”, creates the ability to stretch the cells, “Elasticity”, helps to recoil back after stretching or shortening. And “Excitability” for responding to a stimulus according to the hormone, it functions.

Examples of Muscular Tissue

Contracting and expanding the tissues, the muscle cells function potentially, these structural groups of muscle cells created the muscular tissues. For example, each muscular tissue can be explained as, Skeletal and voluntary muscle is linked with the layer of bones, like arms, hands, legs, necks, and face. In addition, the smooth muscular tissue or involuntary cells which connect with the blood vessels, “iris of the eye, muscle, skin, urinary bladder, uterus and other involuntary organs. Apart from this, the cardiac muscle contracted with the layer of the heart, which helps to pump the heart continuously. 

Structure of Muscular Tissue

The “muscular tissue” performs with a group of cells as a unit which is surrounded by the connective tissue, called “epimysium”.  In addition, above epimysium, a layer of nerve cell covers that runs the long fibers is known as “fascicles”. Another layer has been surrounded, this layer which protects the fascicles is called “perimysium”. These all layers help the muscle to contract or shorten the different muscular parts. 40% of the animal body is skeletal muscle tissue with myofibrils. Running through the blood vessels, these tissues help to move the body organ easily. Controlled by an “Autonomous Nervous System” the involuntary smooth muscle moves down the food to the intestine for digestion. In addition, it creates a link with other organs such as, “blood vessels, reproductive system” and others. A single cell extends 70% of the length of the tissue so that it helps the body of an animal keep moving and stimulating. 

Conclusion

Through the help of the muscular tissue in the animal body, they can move their body parts efficiently. It enables the ability to contract the organs, which consists of thin elongated muscle fibers. Each component of the muscle tissue creates the ability to extend or shorten the parts of the body. The muscular cells interlink the body parts to function together, and the protein fibers present in the body contract every part of the animal body.
