Myofibril - Wikipedia
A myofibril (also known as a muscle fibril or sarcostyle) [1] is a basic rod-like organelle of a muscle cell. [2] . Skeletal muscles are composed of long, tubular cells known as muscle fibers, and these cells contain many chains of myofibrils. [3] . Each myofibril has a diameter of 1–2 micrometres. [3] .

Myofibrilar myopathy (MFM) is a neuromuscular disease characterized by slowly progressive muscle weakness that can involve both proximal muscles (such as hips and shoulders) and distal muscles (those further away from the trunk). Some affected individuals also experience muscle stiffness, aching, or cramps.

Myofibrillar myopathies represent a group of muscular dystrophies with a similar morphologic phenotype. They are characterized by a distinct pathologic pattern of myofibrillar dissolution associated with disintegration of the Z-disk, accumulation of ...
Orphanet: Myofibrillar myopathy
Myofibrillar myopathy (MFM) describes a group of skeletal and cardiac muscle disorders, defined by the disintegration of myofibrils and aggregation of degradation products into intracellular inclusions, and is typically clinically characterized by slowly-progressive muscle weakness, which initially involves the distal muscles, but is highly ...

Myofibrillar myopathies are a heterogeneous group of disorders, characterised by the pathologic finding of myofibrillar disruption on electron microscope with a spectrum of histological abnormalities including excessive desmin accumulation in muscle fibres.
Myofibril - Physiopedia
Individual myofibrils (approximately 1 μm in diameter) comprise approximately 80% of the volume of a whole muscle. The number of myofibrils ranges from 50 per myocyte in the muscles of a fetus to approximately 2000 per myocyte in the muscles of an untrained adult.
