Cell type. A cell type is a classification used to identify cells that share morphological or phenotypical features. [ 1] A multicellular organism may contain cells of a number of widely differing and specialized cell types, such as muscle cells and skin cells, that differ both in appearance and function yet have identical genomic sequences ...
The list of human cell types provides an enumeration and description of the various specialized cells found within the human body, highlighting their distinct functions, characteristics, and contributions to overall physiological processes. Cells may be classified [ 1] by their physiological function, histology (microscopic anatomy), [ 2 ...
The cell is the basic structural and functional unit of all forms of life. Every cell consists of cytoplasm enclosed within a membrane; many cells contain organelles, each with a specific function. The term comes from the Latin word cellula meaning 'small room'. Most cells are only visible under a microscope.
Touton giant cell. Touton giant cells in a juvenile xanthogranuloma. H&E stain. Touton giant cells are a type of multinucleated giant cell seen in lesions with high lipid content such as fat necrosis, xanthoma, and xanthelasma and xanthogranulomas. They are also found in dermatofibroma.
In immunology, a memory B cell ( MBC) is a type of B lymphocyte that forms part of the adaptive immune system. These cells develop within germinal centers of the secondary lymphoid organs. Memory B cells circulate in the blood stream in a quiescent state, sometimes for decades. [1] Their function is to memorize the characteristics of the ...
Somatic cell. In cellular biology, a somatic cell (from Ancient Greek σῶμα (sôma) 'body'), or vegetal cell, is any biological cell forming the body of a multicellular organism other than a gamete, germ cell, gametocyte or undifferentiated stem cell. [ 1] Somatic cells compose the body of an organism and divide through mitosis .
63368. Anatomical terminology. [ edit on Wikidata] In multicellular organisms, stem cells are undifferentiated or partially differentiated cells that can change into various types of cells and proliferate indefinitely to produce more of the same stem cell. They are the earliest type of cell in a cell lineage. [ 1]
Muscle cell. A muscle cell, also known as a myocyte, is a mature contractile cell in the muscle of an animal. [ 1] In humans and other vertebrates there are three types: skeletal, smooth, and cardiac (cardiomyocytes). [ 2] A skeletal muscle cell is long and threadlike with many nuclei and is called a muscle fiber. [ 3]
