Question: Impulses originating in the part of the brain called the medulla would most directly affect which body structure?
a. A leg muscle
b. A ligament
c. An arm bone
d. The heart
Answer:
d. The heart
Explanation:
The medulla oblongata contains a number of reflex centers for regulating vital body functions such as heartbeat, breathing, and vasoconstriction. The medulla contains several nuclei, a collection of neuronal cell bodies.
For example, impulses originated in the cardiovascular center regulates the rate and force of the heartbeat and the diameter of blood vessels. Impulses from the cardiovascular center flow along sympathetic and parasympathetic neurons. An increase in sympathetic stimulation from the cardiovascular center of medulla increases heart rate and contractility while a decrease in sympathetic stimulation decreases heart rate and contractility.
Answer:
Providing energy and regulation of blood glucose.
Sparing the use of proteins for energy.
Breakdown of fatty acids and preventing ketosis.
Explanation:
The main function of carbohydrates is to provide energy and regulation of glucose in the blood. It prevent the use of proteins for production of energy and also promote breakdown of fatty acids and preventing ketosis. Ketosis is a process that occurs when our body doesn't have carbohydrates in sufficient quantity for the production of energy. Carbohydrates are the first biomolecules that are used for energy production.
Vitamin B12 deficiencies can lead to megaloblastic anemia, a condition where the bone marrow produces large abnormally shaped red blood cells that do not function properly. Dementia, paranoia, depression, and behavioral changes can result from a vitamin B12 deficiency. Neurological damage sometimes cannot be reversed
