Muscular Tissues

Muscles are classified as soft tissue. Your Muscular Tissues are made up of a large number of flexible fibres. The human body has around 600 fibres. Muscles provide a multitude of functions. Some muscles help with sprinting, jumping, and delicate tasks like threading a needle. With the assistance of other muscles, you can breathe and digest food. The heart is a strong muscle that beats hundreds of times every minute.

A multitude of conditions, injuries, and diseases can all have an impact on muscle function. These illnesses can cause muscle discomfort, spasms, and weakening. In more severe situations, paralysis is a possibility. Cardiomyopathy and other types of heart disease affect the ability of the heart to pump blood throughout the body.

Muscular Tissue Examples

A muscular tissue example is a type of muscle that may be found in the skeleton. Skeletal muscle, which is attached to the bones, controls skeletal movement. Muscle with a silky texture. Smooth muscle in the walls of hollow internal organs such as blood vessels, the gastrointestinal tract, the bladder, and the uterus is regulated by the autonomic nervous.

Structure of Muscular Tissue

• The muscle tissues are densely packed and bordered with epimysium, a stiff connective tissue that resembles cartilage.

• The epimysium protects a bundle of nerve cells that run in long fibres known as fascicles.

• The fascicles are surrounded by a protective layer called perimysium. It allows nerves and blood to flow freely to individual fibres.

• Another protective layer, the endomysium, covers the fibres.

• These layers and muscles help to contract various muscular components. The bundle pass each other as they contract.

• The epimysium connects to the tendons that run along the periosteum, which is the connective tissue that surrounds the bones. When the muscles tighten, the bones move more easily.

• The epimysium works in conjunction with other connective tissues to apply pressure on the organs and control everything from circulation to food digestion.

Types of Muscular Tissue

Skeletal Muscle Tissue

• The skeleton is linked to these muscles, which help it move.

• These muscles are also known as striated muscles because of the alternating patterns of light and dark bands.

• The bright and dark bands are made up of sarcomeres, which are highly organised structures made up of actin, myosin, and proteins. These improve the contractility and extensibility of the muscles.

• Skeletal muscles are voluntary muscles made up of muscular fibres.

• Skeletal muscles account for 40% of our body weight.

• Myofibrils can be present in all skeletal tissues.

• The cells in these tissues are multinucleated.

• These have blood vessels as well as enlarged mitochondria and glycogen granules.

• They are in charge of the movement of the organs in the body.

Smooth Muscle Tissue

• These non-striated, involuntary muscles are controlled by the Autonomic Nervous System.

• It makes the digestive, urinary, reproductive, and blood vessel systems, as well as the blood vessels and airways, more contractile.

• Since the actin and myosin filaments are so thin and poorly organized, there are no striations.

• The cells are spindle-shaped and feature a single nucleus.

Cardiac Muscle Tissue

• These are exclusively found in the heart.

• Cardiac contractions, which are involuntary muscles, are used by the heart to pump blood.

• Cardiomyocytes are the striated cells that comprise the cardiac muscles.

• The junctions that link the ends of the cells are known as intercalated discs. Desmosomes are the DNA strands that link cells together.

Muscular Tissue Function

• The nerve bundles that link muscular tissues are the same as the nerve bundles that connect nerves in the brain.

• A nerve impulse from the brain causes the muscles to contract.

• Actin and myosin are proteins that are found in all muscle cells. When the contraction signal is received, these proteins move past one another.

• A single cell can be compressed to 70% of its original length. After contraction, a whole muscle shortens.

• Muscular tissues help with bone movement, organ compression, and chamber compression.

What is the Difference Between Tissue and Muscle?

Want to know what is the difference between tissue and muscle? Well, tissue is that connective tissue’s primary job is to connect tissues, organs, and other body components, whereas muscle tissue’s primary function is to carry out physiological motions.

Conclusion 

Muscle tissue possesses properties that allow it to move. Muscle cells are excitable, meaning they react to external stimuli. Because they are contractile, they may shorten and provide a pulling force. When muscles are attached between two movable items, such as bones, they allow the bones to move.
