ANS
CNS generates impulses AWAY via this type of nerve, which initiates motor response
What is an efferent nerve?
Refers to the movement of drugs into, through, and out of the body; what a body does to a drug
What is pharmacokinetics?
The study of drugs
What is pharmacology?
Pacemaker of the heart
What is the SA node?
Chest pain resulting from a fixed and intact plaque lesion, often occurring with exertion and relieved with rest or nitroglycerin
What is stable angina?
Connect valve leaflets to papillary muscles
What are chordae tendineae?
This division controls rest & digest and is responsible for decreasing heart rate and contractility. 75-80% of its nerve fibers pass through Vagus nerve.
What is parasympathetic nervous system?
This permits entry of the drug from site of administration into the blood stream
What is absorption?
The LIVER is the main organ involved in drug ___________
What is metabolism?
This chamber is predominantly a filling chamber
What is an atrium?
Audible blood flow in the heart, typically through a valve
What is a murmur?
Pressure sensitive neurons that help maintain blood pressure at nearly constant levels
What is baroreceptor (reflex)?
This route of administration gets under your skin with IV, IM, or SC
What is parenteral?
Describes what drugs do to the body
What is pharmacodynamics?
Describes the portion of the aorta that gives rise to the coronary arteries
What are the sinuses of Valsalva?
Describes a condition where blood flow is completely cut off resulting in necrosis, or cell death
What is infarction?
Valve pathology demonstrating reduced opening of a valve; most common site is MV due to rheumatic fever
What is stenosis?
Nerves that release norepinephrine at their post ganglionic nerve ending are known as this and are found in the sympathetic nervous system
What is adrenergic?
Measure of strength/concentration of a drug required to produce a specific effect
What is potency?
Drugs that bind to a receptor to produce a drug action are called
What are agonists?
Volume of blood ejected from the heart each minute, calculated as SV x HR
What is cardiac output?
Subendocardial infarction; not always visible on ECG
What is NSTEMI
Leakage of a valve
What is regurgitation/insufficiency?
What is filtration?
Time required for the blood concentration of the drug to fall to half of its original level
What is half-life?
Undesired effects that are not just a nuisance - they may actually be harmful (ie persistent diarrhea)
What are adverse effects?
Percentage of blood ejected from the ventricle with each beat, calculated as (EDV-ESV)/EDV
What is ejection fraction?
Transmural infarction; visible as an elevation on ECG
What is STEMI?
Upon closure, this is the bowing back of valve leaflets behind valve annulus
What is prolapse?
