Intoxication. Alcohol slows all of these.
Answer:
The correct option is b. myelinated axons from many neurons
Explanation:
White matter is an area which is present in the brain and the spinal cord, that are mainly consists of bundles of myelinated axons, also called tracts. The myelinated axons are the nerve fibres that are surrounded by a lipid-rich substance called myelin.
The presence of the myelin gives the tissue the white colored appearance in contrast to the cerebral cortex which is the grey matter.
Therefore, the myelinated axons from many neurons aggregate together to form the white matter present in the brain and the spinal cord.
Answer:
Cardiac output
Explanation:
<u>Cardiac output is the term which is used in the cardiac physiology which describes that the volume of the blood being pumped by heart per unit time. </u>
Cardiac output is product of heart rate, or number of the heart beats per minute and stroke volume which is volume of the blood pumped from ventricle per beat.
Because the cardiac output is related to quantity of the blood delivered to the different parts of body, Cardiac output is an important indicator of the heart'efficiency that whether it can meet body's demands for perfusion.
