The central organ of the nervous system is the brain. It consists of the cerebrum, brain stem, and cerebellum. The largest part of the brain is cerebrum. It is connected to the spinal cord by the brain stem. The long, thin tubular structure that starts from the brain stem (medulla oblongata) and ends at the lumbar region of the vertebral column is called the spinal cord. The spinal cord is composed of nervous tissue.

What are biofertilizers and mention the significance

PCBs and River Otters: Otters in Washington State’s Green-Duwamish River have high levels of polychlorinated biphenyls (PCBs) in their livers. PCBs can bind to the estrogen receptors in animals and disrupt the endocrine system of these otters. The PCBs seem to increase the estrogen to androgen ratio, skewing the ratio toward too much estrogen. How would increased estrogen affect the river otter population? Based on your reading of the materials in this unit, what factors can affect fertility in humans? Explain how each of the factors affecting human fertility that you described can disrupt the human endocrine system to affect reproduction.
