Answer:
This question includes some errors, the question should be written as:
The medulla oblongata controls the contraction and relaxation of the ______ causing the lungs to inflate and deflate during breathing.
Although there are no options, the answer is generally RESPIRATORY MUSCLES i.e. diaphragm and intercostal muscles
Explanation:
Breathing is an involuntary action required to take place in order to get oxygen into the system and carbon dioxide out of the system. However, the process of breathing is neurally controlled by brain portion called RESPIRATORY CONTROL CENTERS.
The Medulla oblongata located in the hindbrain is one of the two respiratory control centers (the other being the PONS). The medulla sends nerve signals to the muscles responsible for bringing about the ventilation process i.e. the DIAPHRAGM and INTERCOSTAL MUSCLES.
This nerve impulse brings about the contraction of the diaphragm, which is the major respiratory muscle, and intercostal muscle causing the lungs to inflate and allow the entry of oxygen-containing air. On the other hand, it also brings about the relaxation of these muscles causing the lungs to deflate allowing the expelling of air.
Answer: The most dangerous virus is the Marburg virus. It is named after a small and idyllic town on the river Lahn - but that has nothing to do with the disease itself. The Marburg virus is a hemorrhagic fever virus. As with Ebola, the Marburg virus causes convulsions and bleeding of mucous membranes, skin and organs. It has a fatality rate of 90 percent.
The first people infected had been exposed to Ugandan imported African green monkeys or their tissues while conducting research. One additional case was diagnosed retrospectively. The reservoir host of Marburg virus is the African fruit bat, Rousettus aegyptiacus.
