Answer:
The correct answer will be option B.
Explanation:
Neurons are the structural and functional unit of the nervous system. Based on the transmission of nerve impulse these neurons can be divided into two divisions :
1. Afferent neurons: Neurons which transmit the impulse from the periphery to CNS- brain or spinal cord. Sensory neurons are such neurons which carry the impulse of stimulus to CNS.
2. Efferent neurons: Neurons which transmit the signals from the CNS to the periphery or muscle which causes voluntary action. Motor neurons are considered efferent neurons.
Thus, option B is the correct answer.
An appropriate response will be to avoid such dramatic weight loss nutrition misinformation, informercial claims which do not have any scientific backing.
- Many consumers are taking control of their own personal health and nutrition decisions due to the rising body of evidence that links diet to overall health.
- As people rely more on sources including websites, television, radio, newspapers, commercials, friends, and family for nutrition information, opportunities for health fraud and nutrition misinformation are growing.
- Health fraud is the misrepresentation of health claims, which can take many different forms, from a self-declared medical expert who has found a purported "wonder cure" to a food supplement or drug that is advertised with erroneous health claims.
- Science-based, peer-reviewed, and reproducible are all characteristics of accurate nutrition information.
- Science does not support nutrition misinformation, and it may also be inaccurate and incomplete. hence only scientifically proven nutritional supplements should be taken.

During foetal stag of development the embryo develops the germinal epithelium of ovary .some of the cells of germinal epithelium enlarge and divide mitotically . the dividing cells projects into the stroma as a cord known as the egg tube of Pflugar;which later becomes a round mass ,called the egg nest .all these dividing cells are egg mother cells known as Oogonia.this is derived from the endodermal lining of the embryonic yolk sac which comes to lie in the ovary of the female ( while it is still an embryo ).
What is primary oocyte?
One cell of the egg nest grows but does not divide furter so as to form the primary oocyte.the primary oocyte is diploid and enters the growth phase.it is dormant stage ,nucleus intact ,female is born with these in her ovary.every month primary oocytes resume oogenesis and start developing growth and development in the onset of puberty.
