Somatic features (morphometric or meristic features, i.e., body weight, length of body, tail, hind foot and ear) and reproduction characteristics (number of embryos in uterus, reproduction potential, duration of reproduction season) are the basic attributes of the biology of a species.
What is an example of somatic?
Somatic cells are the cells of an organism that are not germ cells, or reproductive cells. Somatic cells are highly specialized and can be very different from one another. Some examples of somatic cells include nerve cells, skin cells, and blood cells.
What is the meaning of somatic in biology?
The term somatic – etymologically from the French word “somatique”, from Ancient Greek “σωματικός” (sōmatikós, “bodily”), from σῶμα (sôma, “body”) – is often used in biology to refer to the cells of the body in contrast to the reproductive (germline) cells, which usually give rise to the egg or sperm (or other gametes …
What is somatic variation example?
Somatic variation pertains to diversity in the plant body or any non-germinal cell, tissue, structure or process. Somatic polymorphism is the genetically controlled expression of diverse plant parts and processes independent of environment: e.g. cotyledons and true leaves in plants are both leaf tissue.
What do you mean by somatic part?
of the body; bodily; physical. Anatomy, Zoology. pertaining to the body wall of an animal. Cell Biology. pertaining to or affecting the somatic cells, as distinguished from the germ cells.
What are somatic functions?
The somatic nervous system is part of the peripheral nervous system. Major functions of the somatic nervous system include voluntary movement of the muscles and organs and reflex movements. In the process of voluntary movement, sensory neurons carry impulses to the brain and the spinal cord.
What are somatic actions?
The somatic nervous system controls voluntary movements, transmits and receives messages from the senses and is involved in reflex actions without the involvement of the CNS so the reflex can occur very quickly.
Are skin cells somatic?
Every other cell type in the mammalian body, apart from the sperm and ova, the cells from which they are made (gametocytes) and undifferentiated stem cells, is a somatic cell; internal organs skin, bones, blood and connective tissue are all made up of somatic cells.
Are somatic cells tissues?
Somatic cells are the cells of the body that make up different tissues and organs. They are therefore important because they make up various parts of the body including all the internal organs, the connective tissue, and bones among others.
What is the somatic phase?
The somatic phase consists of coenocytic mass of highly granular protoplasm containing hundreds or thousands of nuclei and vacuoles without cell walls, but delimited only by a thin plasma membrane—a plasmodium (pl. plasmodia) (Fig. 321A).
What is somatic polymorphism?
Abstract. SOMATIC seed polymorphism is the production of seeds of different morphologies or behaviour on different parts of the same plant and is a somatic differentiation rather than the result of genetic segregation1.
What is somatic variation class 10th?
(i) Somatic variation : Somatic variation affects the somatic cells of an organism. It is neither inherited from parents nor transmitted to next generation. It is acquired by individual during it’s own life and is lost with it’s death. It is therefore also called a acquired variation or blastogenic variation.
What’s the difference between somatic and germline?
Somatic mutations – occur in a single body cell and cannot be inherited (only tissues derived from mutated cell are affected) Germline mutations – occur in gametes and can be passed onto offspring (every cell in the entire organism will be affected)
Is somatic the same as physical?
Sometimes when there is no medical illness that fully explains the complaint, it may be that emotions are being felt as physical symptoms. Physical symptoms of emotional distress are called somatic symptoms. Somatization is the name used when emotional distress is expressed by physical symptoms.
What is somatic training?
Somatic exercises involve performing movement for the sake of movement. Throughout the exercise, you focus on your inner experience as you move and expand your internal awareness. Many types of somatic exercises exist.
What is somatic philosophy?
Somatic theory is a theory of human social behavior based loosely on the somatic marker hypothesis of António Damásio, which proposes a mechanism by which emotional processes can guide (or bias) behavior, particularly decision-making, as well as the attachment theory of John Bowlby and the self psychology of Heinz …
