Body membranes – types of membranes in the body
The scale, shape, and arrangement of fibers in skeletal muscles varies greatly. They vary in size from tiny strands like the stapedium muscle in the middle ear to massive masses like the thigh muscles. Some skeletal muscles have a wider shape while others have a narrow shape. The fibers run parallel to the muscle’s long axis in some muscles, converge to a narrow connection in others, and are oblique in others.
A single cylindrical muscle cell makes up each skeletal muscle fiber. A skeletal muscle is made up of hundreds, if not thousands, of muscle fibers that are packed together and covered in connective tissue. The epimysium is a connective tissue sheath that surrounds each muscle. Fascia is a connective tissue that covers and divides the muscles outside of the epimysium. Parts of the epimysium protrude into the muscle, dividing it into compartments. A bundle of muscle fibers is contained in each compartment. A fasciculus is a bundle of muscle fibers that is surrounded by a layer of connective tissue called the perimysium. Each individual muscle cell, called a muscle fiber, is surrounded by connective tissue called the endomysium inside the fasciculus.
Human heart structure and function | chapter circulation
By enveloping perimysium connective tissue, myocytes form muscle fascicles.
 Epimysium connective tissue binds fascicles together.
The potato experiment – osmosis lab
 Muscle fascicles usually contain only one type of muscle cell (either type I or type II), but they may contain a mix of both.
Ligaments of the knee
 Fascicules, also known as bundle branches, are specialized muscle fibers in the heart that transmit electrical impulses from the atrioventricular node (AV node) to the Purkinje fibers.
Muscles of the hip and thigh – human anatomy | kenhub
[requires citation] The bundle of His begins as a single fascicle of fibers at the AV node, splitting into three bundle branches: the right fascicular branch, left anterior fascicular branch, and left posterior fascicular branch.
Dermatomyositis can be diagnosed using muscle fascicle structure. Myocytes near the muscle fascicle’s edges are usually narrower, whereas those near the muscle fascicle’s core are of normal thickness. [number four]

The epimysium is the muscle’s outer connective tissue covering. Fascicules are small subdivisions within the muscle. These muscle fascicles are surrounded by the perimysium. The endomysium is the protective coating that covers each muscle fiber. A muscle cell’s plasma membrane is known as the sarcolemma. The cytoplasm of a muscle cell is called sarcoplasm.
A muscle cell’s contractile protein is called myofilaments. Actin and myosin are myofilaments. Actin is the thin filaments, and myosin is the dense filaments. A muscle fiber is a muscle cell. “Muscle cell” and “muscle fiber” are interchangeable words. A myofibril is a muscle cell’s longitudinal bundle of myofilaments. The myocardium is the heart’s muscular layer. As a consequence, the myocardium is made up of cardiac muscle.

2-minute neuroscience: the meninges
Connective tissue’s ultimate purpose is to unite or connect body structures and to provide support. The static structure for protection is provided by bone, which is a connective tissue. Dense fibrous connective tissue, rich in collagen fibers, covers the ends of the bones where they articulate, enabling movement while maintaining stability. Another connective tissue found in joints is cartilage, which serves as a compressible connection between two bones or a low-friction surface for smooth movement of one bone over another. Muscles are attached to bone by connective tissue, which comes in the form of a cord (tendon) or a flat layer (fascia). The connective tissues are classified as follows:
Dense fibrous connective tissue connects body structures while also allowing mobility. It has a high tensile strength, which allows it to withstand stretching forces. There are few cells in this connective tissue, which is mostly made up of collagen and elastin fibres that give the tissue its strength. Fibroblast cells that lie between the fibres create the fibres (Figure 1.1). When cutting into stewing steak with a blunt knife, the resilience of this tissue can be felt. The muscle fibers are quickly cut, but the white connective tissue covering is extremely tough. The following are some examples of this tissue:
