In cellular biology, the term somatic is derived from the French somatique which comes from Ancient Greek σωματικός (sōmatikós, “bodily”), and σῶμα (sôma, “body”.) [1] [2] is often used to refer to the cells of the body, in contrast to the reproductive cells, which usually give rise to the egg or sperm (or other gametes in other organisms).
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.
For example, in mammals, somatic cells make up the internal organs, skin, bones, blood, and connective tissue. [1] In most animals, separation of germ cells from somatic cells (germline development) occurs during early stages of development. Once this segregation has occurred in the embryo, any mutation outside of the germline cells can not be ...
In addition, stem cell are undifferentiated cells which can develop into a specialized cell and are the earliest type of cell in a cell lineage. [2] Due to the differentiation in function, somatic cells are found only in multicellular organisms, as in unicellular ones the purposes of somatic and germ cells are consolidated in one cell.
An autosome is any chromosome that is not a sex chromosome.It is commonly known as Somatic chromosome. [1] The members of an autosome pair in a diploid cell have the same morphology, unlike those in allosomal (sex chromosome) pairs, which may have different structures.
Somatic (biology), referring to the cells of the body in contrast to the germ line cells Somatic cell, a non-gametic cell in a multicellular organism; Somatic nervous system, the portion of the vertebrate nervous system which regulates voluntary movements of the body; Somatics, a group of alternative medicine approaches, experiential movement ...
An application of the study of somatic mosaicism in the brain could be the tracing of specific brain cells. Indeed, if the somatic L1 insertions occurs in a progenitor cell, the unique variant could be used to trace the progenitor cell's development, localization, and spreading through the brain. On the contrary, if the somatic L1 insertion ...
A relationship between mean cell number and cell number variation was established following a law possessing an exponent of 2 upon a variety of multicellular eutelic taxa. [ 7 ] Hydatina senta (Phylum Rotifera, Order Bdelloidea ) is a species of rotifers which demonstrate the most complete cell constancy of any species studied before 1912. [ 8 ]
