Flag question: Question 1 Question 1 0 pts

Neurotransmitters are defined by four essential characteristics. These are:

Group of answer choices

Neurotransmitters are synthesized within presynaptic neurons.

Depolarization of a neuron results in the release of a neurotransmitter, which exerts a multitude of actions on the postsynaptic neuron.

Their action on postsynaptic neurons can be replicated by administering a drug that mimics the activity of the endogenous neurotransmitter.

Their action in the synaptic cleft is terminated by a specific action.

A, C, and D only

Flag question: Question 2 Question 2 0 pts

Upon blocking a Serotonin reuptake pump, what happens in the synaptic cleft and on the post synaptic cell membrane?

Group of answer choices

The result will be an increase in available Serotonin in the synaptic cleft causing the post synaptic cell to increase the number of Serotonin receptors.

The result will be an increase in the available Serotonin in the synaptic cleft causing the post synaptic neuron to reduce the number of Serotonin receptors.

The result will be an increase in Serotonin in the synaptic cleft resulting in an increase in reuptake pumps on the presynaptic neuron.

The result will be an increase in Serotonin in the synaptic cleft resulting in a decrease in reuptake pumps on the pre-synaptic neuron.

Flag question: Question 4 Question 4 0 pts

¹Neurons are classified in several different ways. From the following statements, select which ones are true.

1. The two structural classifications are projection neurons and local inter-neurons.
2. Function classifications are made up of two subcategories: excitatory and inhibitory.
3. Histological classification includes bipolar, unipolar, and multipolar.
4. Classifications using a combination of structural, functional, and neurotransmitter type provide the most robust and useful description.
5. Classification by neurotransmitter type alone provides the most useful description.

Group of answer choices

Slow effector pathways

Modulated effector pathways

Rapid effector pathways

Group of answer choices

True

False

Flag question: Question 7 Question 7 0 pts

Serotonin (5HT) is a neurotransmitter associated with mood, sleep, and psychosis. There are several serotonin receptors all over the human body. A unique aspect of the second generation antipsychotics is their ability to block 5HT2a receptors. What is the effect of this inhibition?

Group of answer choices

Stabilizes dopamine concentrations in the CNS

Induces anxiety

Causes hallucinations

Reduces platelet function

Flag question: Question 8 Question 8 0 pts

Treatment adherence is affected by several different factors. Clinical factors include mood, anxiety, psychosis, and substance misuse. There are also patient factors such as knowledge, attitude, and beliefs; economic and racial/ethnic disparities, and clinical encounters. A patient who presents hopeless, with decreased energy, and poor concentration is affected by which factor?

Group of answer choices

Substance misuse

Knowledge deficits

Attitude ad belief system

Mood

Flag question: Question 9 Question 9 0 pts

If a patient admits to taking his medication every other day (instead of daily, as prescribed), a potential concern would be:

Group of answer choices

Sufficient understanding or acceptance of the illness

Abuse of the medication

Expense

Is the desired effect recognized at a lower daily dose?

Flag question: Question 10 Question 10 0 pts

The human brain is subcategorized into four major structures. These structures include the cerebral cortex, brainstem, subcortical structures, and the cerebellum. Of these major categories, which one houses the area of the brain that has been found in some neuropathological studies of patients with schizophrenia to be of smaller size?

Group of answer choices

Cerebral cortex

Brainstem

Subcortical structures

Cerebellum

Flag question: Question 13 Question 13 0 pts

Glia cells play a supportive role to the neuron. A few of the functions of the glial cells include providing nutrition, maintaining homeostasis, stabilizing synapses, and myelinating axons. The glial cells are categorized as microglia and macroglia. Of these two cell types, which one plays an active and critical role in glutamatergic neurotransmission by providing a co-agonist required for glutamate receptor function?

Group of answer choices

microglial

macroglial

Flag question: Question 14 Question 14 0 pts

The synaptic cleft is best characterized by which of the following statements?

Group of answer choices

The synaptic cleft is the space between a single neuron’s dendrites and axon terminals in which intracellular communication occurs through the release of neurotransmitters allowing for signal conduction throughout the central nervous system.

The synaptic cleft is the space between the cell body and axon terminals that allows for release of neurotransmitters from the presynaptic neuron for intercellular communication with an adjacent neuron (post synaptic neuron).

The synaptic cleft is an area where dendrites and axon terminals are within close proximity, allowing for the release of a neurotransmitter from a presynaptic neuron that can interact with receptors on dendritic cells of a post synaptic neuron, which is the main basis for intercellular communication of neurons.
