Highlighted structure is median nerve cord only.
It originates from brachial plexus from medial and lateral cords. Lateral wire best medial and lateral cords lateral and posterior cords medial cord handiest.
The medial twine is the a part of the brachial plexus fashioned with the aid of of the anterior department of the lower trunk (C8-T1). Its name comes from it being medial to the axillary artery as it passes through the axilla. the opposite cords of the brachial plexus are the posterior cord and lateral cord.
The lateral cord gives rise to the lateral pectoral nerve. The posterior wire offers upward push to the higher subscapular nerve, thoracodorsal nerve and decrease subscapular nerve. The medial wire offers upward thrust to the medial pectoral nerve, medial cutaneous nerve of the arm and medial cutaneous nerve of the forearm.
The posterior cord is part of the brachial plexus. It includes contributions from all the roots of the brachial plexus. Posterior twine. Plan of brachial plexus.

ANSWER: Human beings have been manipulating the genetic characteristics plants and animals since the introduction of agriculture indirect manipulation of human genes occurred with widespread use of public health and medical measures that preserve genes causing disease. The production of biologicals by DNA technology raises few ethical problems. Predictive medicine in which genetic markers (including DNA variants) are used for antenatal and preclinical diagnosis of genetic diseases and susceptibilities poses new questions of confidentiality, private versus societal goals, and self-determination. When normal DNA is used to treat the somatic cells of patients with hemoglobinopathies and other genetic diseases, no new ethical problems arise beyond those presented by an novel theory. In contrast, manipulation of DNA in human fertilized eggs would constitute a qualitative departure from previous therapies since this would affect future generations. In order to be able to make wise decisions on these matters the public must be well informed. Thus, formal and informal education in human biology and genetics must be improved at all levels.
Explanation:
Answer:
Generally the genetic composition of every individual are conserved in the DNA, which are expressed as Genes. <u>The part of DNA that codes fro a particular protein is called Gene. </u>These genes were inherited from individual parents by offspring during genetic processes, and are passed to next generation of initiated by the offspring.Therefore the type of characteristics or traits manifested by an individual are results of gene expressed in DNA.
<u>These traits are usually encoded as transcribed bases in mRNA, and when fully translated they are expressed as proteins . Thus each trait are translated protein. This explains the forms of transport of genetic materials from parents to offspring. </u>
<u />
The inherited traits can expressed itself fully in the offsping irrespective of other characteristics, e.g a white man who marries a black woman and all the kids are white with long hair, shows dominance of the white allele, expressed as protein, despite the presence of the black allele. such black allele is said to be recessive.
The independent assortment of genes at meiosis, the crossing over at prophase 1, and separation of the chromosomes at Anaphase 1 and II together with random fertilization by million of genetically varied haploid sperm cells ensured that no two individual are 100 % genetically identical even if they are from the same parents.
The crossing over of genetic materials ensures mixing of these material to give a genetically unique organisms from mixture of the parents DNA. In addition the independent assortment of genes ensures that homologous chromosomes do not continue their 'journey' into the same sex-cells, and therefore the genetic component of the new sex-cells (sperm or oocytes ) and the resultant offspring varies
<u>Furthermore, segregation of genes into different sperm cells and eggs cells ensures random distribution of the DNA in million of sperm cells and therefore varied traits because this DNA distribution can not be the same in each sperm or egg cells, ensuring great variation in the eventual offspring.</u>
