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.

This is called convergent evolution. Convergent evolution also results in the development of similar traits in the distantly related organisms that are found in distantly located geographical regions having similar environmental conditions. Therefore, the presence of the same features in rodents and flying squirrels represent convergent evolution.
