Question

20. Milgram (1961) conducted a study in which volunteers were asked by a professor to s study find? deliver increasingly severe electric shocks to another person. What did thi most volunteers refused to obey the professor and did not deliver severe electric shocks to another person most volunteers obeyed the professor and delivered severe electric shocks to another 21, which term refers to the gap between the axon terminal and the dendrite? synapse threshold b. c. refractory period action potential 22. Which type of neurons convey information between neurons? interneurons sensory neurons motor neurons b. 23. The function of dendrites is to a. receive incoming messages from other neurons b. c. d. release neurotransmitters into the synaptic gap between neurons insulate the axon so that electrical signals are transmitted more efficiently control pain through the release of chemicals into the brain Which structure of the neuron releases neurotransmitters? a. cell body 24. b. c. d. axon terminal myelin sheath 5, Multiple sclerosis is a disease that involves an abnormal increase in the thickness of brain stem the degeneration of the myelin sheath, slowing or interrupting the transmission of neural messages the gradual decline in the ability of neurons to produce neurotransmitters abnormal levels of dopamine in the brain b. c. d. -26. Which of the following best defines a neurotransmitter? a. a chemical messenger that crosses the synapse between neurons b. a fatty tissue that surrounds the axon c. a fiber that extends out of the cell body d. a miroscopic channel through which sodium and potassium ions pass 27, which neurotransmitter is involved in the pleasure center of the brain? a. acetylcholine c. dopamine d. serotonin 28, Heroin is a drug that is chemically similar to endorphins and thus binds to the same receptor sites. As such, heroin is a a. endorphins agonist b. endorphins antagonist

Explanation / Answer

20.

Milgram's study was focused to investigate the effect of authority in the behavior of obedience and the extent of this obedience under authority. In this experiment, most of the participants were ready to deliver high voltage to other persin under the authority of the professor.

Answer. Option b. Most volunteers obeyed the professor and delivered severe electric shocks to another person.

21.

The minute gap between the axon terminal and dendrite through which nerve impulses pass as neurotransmitters is called synapse.

Answer. Option a. Synapse.

22.

Interneurons also called associative neurons or intermediate neurons carry information between sensory neurons and motor neurons. They are found in the Central Nervous System.

Answer. Option a. interneurons.

23.

Dendrites are the branched extension of the cell body of a neuron. The dendrites receive impulses and send it towards the cell body.

Answer. Option a. recieve incoming messages from other neurons.

24.

Answer. Option c. axon

25.

Answer. Option b. the degeneration of the myelin sheath, slowing or interrupting the transmission of neural messages.

26.

Answer. Option a. a chemical messengers that crosses the synapse between neurons.

27.

Answer. Option d. serotonin

28.

Answer. Option a. endorphins agonist.
