Glossary
Term Definition Acetylcholine Neurotransmitter of the parasympathetic nervous system
AV node
A part of the electrical conduction system of the heart that coordinates the top of the heart. It electrically connects the atria and ventricles.
Cardiac output The volume of blood pumped by the heart each minute. It is a product of heart rate and stroke volume
Depolarisation A sudden change in membrane potential – usually from a (relatively) negative to positive internal charge
Heart rate The number of heart beats in a minute
Hyperpolarisation A change in a cell's membrane potential that makes it more negative.
Medulla oblongata One of the brain structures that connects the higher levels of the brain to the spinal cord, and is responsible for several functions of the autonomous nervous system
Membrane potential The difference in electric potential between the interior and the exterior of a biological cell
Noradrenaline Neurotransmitter that is released predominantly from the ends of sympathetic nerve fibres to increase the rate and force of contraction of the heart
Sinus node The heart's natural pacemaker. It consists of a cluster of cells that are situated in the upper part of the wall of the right atrium (the right upper chamber of the heart). The electrical impulses are generated there.
Vasoconstriction The narrowing of the blood vessels resulting from contraction of the muscular wall of the vessels
Venous return The flow of blood back to the heart
