Neuro Flashcards
Chemical synapses are the primary mechanism by which neurons communicate. They may be either:
Excitatory or inhibitory.
Synaptic transmission involves all of the following except:
Activation of transmitter.
When a neuron is depolarized, what happens?
The chemical transmitter is released.
The single most time–consuming step in the process of synaptic transmission is:
Fusion and exocytosis.
Glycine is an inhibitory neurotransmitter in the spinal cord that catalyzes the opening of:
Cl- channels.
Nicotinic ACh receptors are typically found in:
Skeletal muscle end plates.
All of the following neurotransmitters may be excitatory except:
Dopamine.
The autonomic nervous system anatomy is generally divided into two primary sections. The organization of the autonomic nervous system is based upon:
Anatomy or chemistry.
The reason that cholinergic discharge is discrete and of short duration is that:
Acetylcholinesterase typically breaks down acetylcholine immediately upon its discharge.
The classic “fear/flight/fight” response is a consequence of widespread noradrenergic discharge and is characterized by:
Lowered threshold in the reticular formation.
Toxic epidermal necrolysis is characterized by:
The potential for full recovery.
The primary neurotransmitter deficiency that characterizes the pathophysiology of depression is:
Norepinephrine.
Medical conditions that may predispose to or exacerbate depression include all of the following except:
Hyperparathyroidism.
Selective serotonin reuptake inhibitors are the most commonly- prescribed medication for depression. Mild forms of serotonin syndrome include:
Tremor.
The pathophysiology of seizure disorder can be best described as:
Excessive neuronal discharge.
