Answer:
Role of nervous system in Parkinson's disease:
Parkinson's disease is a neuro disorder that affects the nerve cells. The neurons responsible for the body movement is affected in this disease. The neurons that produce dopamine, dies in the parkinson's disease and result in the conditions like slowness, tremor and stiffness.
Role of nervous system in Alzheimer's disease:
Alzheimer's disease is a type of dementia that loses the individual's ability to think and memorize the things. The brain tissue is degenerated in this disease. The nerve cell loses its function and the protein beta amyloid get deposited in this disease.
A patient has been diagnosed with angina. As he talks with the nurse, he asks several good questions about angina and seems able to concentrate on the explanations. He seems eager to learn how to manage his condition. What assessment can be made by the nurse <u>Hardiness</u>
<h3>What is
angina?</h3>
Chest pain or pressure, often known as angina or angina pectoris, is a sign of coronary heart disease and is typically brought on by insufficient blood flow to the heart muscle (myocardium).
A blockage or spasm of the arteries that feed blood to the heart muscle is typically the cause of angina. Anemia, abnormal cardiac rhythms, and heart failure are among additional factors. Atherosclerosis, a component of coronary artery disease, is the primary mechanism of coronary artery occlusion. The phrase means "a strangling feeling in the chest" and is derived from the Latin words angere ("to strangle") and pectus ("chest").
The degree of oxygen deprivation in the heart muscle and pain intensity are only weakly correlated.

Answer:
A. Antagonist
Explanation:
The triceps, acting in opposition, is called the antagonist. Because the two muscles are located on opposite sides of the arm, the triceps must relax enough to allow the biceps to tense and contract during a curl. As it contracts, it shortens. As the triceps relaxes, it lengthens. (google)
I think B. enterogastric reflex: One of three extrinsic reflexes of the gastrointestinal tract that is stimulated by the presence of acid levels in the duodenum or in the stomach that cause the release of gastrin from the G cells in the antrum of the stomach.
Answer:
The chemical receptors of cells have been defined as molecular structures to which other molecules considered as chemical messengers (neurotransmitters, hormones and other neuroactive molecules) specifically bind.
Chemical receptors can be located on the plasma membrane into which they insert by crossing it. Membrane domains have been defined for them and also on both sides of the membrane. The one on the external side corresponds to the binding site for messengers that come from other cells, a situation that defines the so-called heteroreceptors. If messengers coming from the cell itself join that site, the so-called autoreceptors are defined.
But chemical receptors can also be located inside cells. They are intracellular receptors and are found in the cytoplasm or in the nucleus. Messages act on them, which due to their chemical nature can cross the plasma membrane, such as steroidal hormones, thyroid hormones and neurosteroids
