Cardiac
Open ______ channels are responsible for maintaining voltage in resting state.
Potassium (K+)
I cause folks to lose all their dopamine neurons and let acetylcholine run the show. You'll recognize me by my shuffling gait.
Associated with "slow pain" impulse transmission. The unmyelinated fibers are responsible for deep, aching pain
C-Fibers
The conversion of a pain-producing stimulus to a nerve impulse is known as...
Transduction
I'm the pleasure neurotransmitter, closely connected to addiction. A deficiency of me results in bradykinesia.
Dopamine
The valve responsible for preventing backflow into the left atrium is the...
Mitral Valve
I'm associated with progressive memory loss, too much glutamate and the formation of brain plaques.
Alzheimers Dementia
This pain processing pathway converts a stimulus into an electrical impulse
Transduction
"Fast pain" receptors are generally described as....
Felt within 0.1 seconds of the stimulus
Acetylcholine
After an electrical stimulus is generated by the AV Node, which ion channels open to affect the depolarization in stage 0?
Na+
A patient with Alzheimers is experiencing memory loss. Which part of the brain is losing neurons?
Limbic System
A patient demonstrates this phenomenon when he recoils and screams with a light touch to the shoulder.
Allodynia
The patient in severe pain is hypersensitive to stimuli and is chronically in a strong state of arousal because of strong arousal in the....
Reticular formation
Which of the following events occurs first during mechanical contraction of the myocardium?
calcium is released from sarcoplasmic reticulum
The specialized rapid conduction tissue that is important to ventricular muscle contraction is known as....
His-Purkinje System
Central Nervous system disorders due to excitotoxic injury usually involve which neuro transmitter
Glutamate
These three Greek letters represent the three types of opioid receptors.
Mu, Kappa, Delta
The majority of cases of hemophilia are due to a deficiency of....
Factor VIII
In contractile cells, what is happening to Na+ channels in phase 3?
h gates recover
Among the variety of tissue types found in cardiac muscle, which type has the greatest ability to beat autonomously?
Sinoatrial (SA) node tissue
An imbalance of neurotransmitter beginning with a decrease in dopaminergic neurons is the underlying problem in....
Parkinson's Disease
I'm a primary inhibitory neurotransmitter. If you give your patient Ativan, it will bind to me, open up chloride channels and inhibit neuronal firing
GABA
The force that the myocardium must develop for the cells of the ventricle to shorten is called....
Afterload
Treatment of a patient with excessive bleeding caused by disseminated intravascular coagulation can include the use of....
Heparin
