Answer:
A brain concussion
Explanation:
This is the effect when a person suffers a brain knock due to an accident or by playing contact sports like in this case.
Depending how hard was the hit, the brain can suffer different effects, this is due to the lost of the brain liquid that support it. The lost of memory is one of the effects, that can be due to the area that suffer the hit. Depending the are of the brain that was damage.
Hope this info is helpful.
Answer:
A. epinephrine
Explanation:
Bronchial constriction usually involves the tightening of the smooth muscles which surrounds the tube-like bronchial airways. This occurs via extra mucus production, spasming of smooth muscles, or swelling/inflammation of layers within bronchi or bronchioles. Bronchial constriction typically results in symptoms of wheezing, coughing and shortness of breath.
This can be treated via the use of the hormone epinephrine, a bronchiodilator. For some cases like asthma, epinephrine in small aerosolized (inhaled) doses can lead to the <em>temporary</em> relief of symptoms. Epinephrine acts by making bronchial tubes wider to allow the passage of air.
In the body, smooth muscle cells in the veins, arteries and heart are under the control of epinephrine receptors called β2 receptors. Epinephrine binding to the receptor triggers a cell signalling cascade that activates β2 receptors to dilate smooth muscle in the lungs.
Here's how-
- Calcium is essential to mediating muscle cell signalling and thus contraction
- in the lungs, epinepherine-β2 receptor binding leads to enzyme activation (adenylyl cyclase)
- conversion of the energy molecule ATP to the secondary messenger molecule cyclic AMP.
- cAMP inhibits the activity of the enzyme <em>myosin light chain kinase </em>(MLCK) in smooth muscle
- ∴ the enzyme remains inactive and the muscles relax
<em>Summary:</em><em> epinephrine → muscle relaxation →</em><em> bronchial dilation (reduced diameter) </em><em>→ decreased respiratory distress → easier breathing.</em>
Well <span>"processed foods" can be bad or harmful its the way you treat it and make it i can see why the media does this to avoid people from deseases and cancer ect my opinion processed foods are bad.Hope this helped </span>
