Axon Terminals
Correct Answer
A. Myelin SheathExplanation
The myelin sheath is a protective covering that surrounds the axon of a neuron. It is made up of fatty substances called myelin, which insulate the axon and increase the speed at which the neural message travels within the neuron. The myelin sheath acts as an electrical insulator, preventing the loss of the neural signal and allowing it to travel more efficiently along the axon. This helps to speed up the transmission of information within the nervous system. Schwann cells are responsible for producing the myelin sheath in the peripheral nervous system. Dendrites receive incoming signals, while axon terminals transmit signals to other neurons.Rate this question:

The action potential can be described as
- A.
The cell body regulating the nucleus
- B.
The electro-impulse moving through the entire neuron
- C.
The receiving of an impulse by the axon terminals
- D.
The direction an impulse travels through a nerve cell
Correct Answer
B. The electro-impulse moving through the entire neuronExplanation
The action potential refers to the electro-impulse that moves through the entire neuron. It is an electrical signal that travels along the neuron, starting from the dendrites, passing through the cell body, and reaching the axon terminals. This electro-impulse is generated when the neuron receives a stimulus, causing a rapid change in the electrical potential across the cell membrane. This change in potential triggers the action potential, which then propagates along the neuron, allowing for the transmission of information.Rate this question:

The all or nothing phenomenon for action potential can be described as
- A.
An impulse either fires through a neuron or it doesn't
- B.
The myelin sheath speeds the impulse
- C.
The impulse gets blocked by the Nodes of Ranvier
- D.
The impulse reverses course and exits the dendrite
Correct Answer
A. An impulse either fires through a neuron or it doesn'tExplanation
The all or nothing phenomenon refers to the fact that once a neuron reaches its threshold potential, an action potential is generated and it will propagate along the neuron's axon to the end. If the threshold is not reached, no action potential will be generated and the impulse will not propagate. This phenomenon ensures that the transmission of signals in the nervous system is reliable and consistent.Rate this question:

Psychoanalysis is best described as behavior that
- A.
Is learned
- B.
Bubbles out of the unconscious
- C.
Results from tradition or culture
- D.
Is developed over several generations of species
Correct Answer
B. Bubbles out of the unconsciousExplanation
Psychoanalysis is best described as behavior that "bubbles out of the unconscious" because psychoanalysis is a psychological theory and therapy approach developed by Sigmund Freud. According to Freud, the unconscious mind is a reservoir of thoughts, desires, and memories that are hidden from conscious awareness but still influence behavior. Psychoanalysis aims to bring these unconscious thoughts and desires into consciousness, allowing individuals to gain insight into their behavior and make changes. Therefore, the behavior described in psychoanalysis is believed to originate from the unconscious mind and "bubble out" into conscious behavior.Rate this question:

- A.
APA Guidelines
- B.
Hawthorne Experiment
- C.
Stanford Prison Experiment
- D.
Tuskegee Experiment
Correct Answer
C. Stanford Prison ExperimentExplanation
Dr. Philip Zimbardo is best known for the Stanford Prison Experiment. This infamous psychological study conducted in 1971 aimed to investigate the effects of perceived power on individuals' behavior. Zimbardo and his team simulated a prison environment, randomly assigning participants to be either guards or prisoners. The study quickly spiraled out of control as the guards began to exhibit abusive behavior towards the prisoners. The experiment was halted after only six days due to the severe psychological distress experienced by the participants. The Stanford Prison Experiment continues to be a significant case study in understanding the power of social roles and situational influences on human behavior.Rate this question:
