Jul 1, 2016 · Neurogenic type atrophy is a descriptive diagnosis that has multiple different etiologies; underlying etiology generally cannot be further elucidated by the muscle biopsy itself and needs clinicopathologic or radiologic correlation

Jun 3, 2024 · The main histologic feature of skeletal muscle atrophy is a reduction in myofiber diameter (Figure 1 and Figure 2). Affected myofibers are often rounded to angular with hypereosinophilic sarcoplasm. In denervation atrophy, the characteristic histologic feature is that of compressed angular myofibers with crowded nuclei.

Atrophy, decrease in size of a body part, cell, organ, or other tissue. Atrophy is a hallmark of conditions such as starvation, aging, and certain disease states. It also occurs normally in some cells and organs at certain life stages. Learn more about the …

Mar 19, 2024 · What is atrophy? what are the types? Atrophy is a form of cellular adaptation characterized by a decrease in cell size or number, affecting the overall size of an organ or tissue. It can be classified into two types:

Jul 17, 2023 · Severe atrophy can show dirty background with inflammation, debris, old blood, blue blobs and giant cells In liquid based cytology, background of atrophic smear is cleaner May resemble urothelial metaplasia, but cells have prominent intercellular bridges

May 13, 2004 · Atrophy is a general physiological process of reabsorption and breakdown of tissues, involving apoptosis on a cellular level. It can be part of normal body development and homeostatic processes, or as a result of disease.

Type II atrophy: Pathology. Type II (Dark at pH 9.4) Muscle fibers Small: Reduced cross-sectional area\ Shape Adult: Angular or Elongated; Childhood: Polygonal or Round; Early changes Atrophy: Type IIB (Intermediate staining at pH 4.6; Myosin 2A+2X) fibers More IIB muscle fiber atrophy in males than females 2

Atrophy is defined as a decrease in the size of a tissue or organ due to cellular shrinkage; the decrease in cell size is caused by the loss of organelles, cytoplasm and proteins. This Review discusses the latest findings and emerging concepts related to pathways controlling muscle atrophy in physiological and pathological conditions.

Muscle atrophy is defined by changes in the muscles, consisting in shrinkage of myofibers, changes in the types of fiber and myosin isoforms, and a net loss of cytoplasm, organelles and overall a protein loss.

The main histologic feature of skeletal muscle atrophy is a reduction in myofiber diameter (Figure 1 and Figure 2). Affected myofibers are often rounded to angular with hypereosinophilic sarcoplasm. In denervation atrophy, the characteristic histologic feature is that of compressed angular myofibers with crowded nuclei.
