Question 1

Which cells in the nervous system receive,integrate,and transmit information&#10;A)&#160;glia&#10;B)&#160;synapses&#160;&#10;C)&#160;terminal buttons&#10;D)&#160;neurons

Accepted Answer

Neurons are the cells that receive, integrate, and transmit information in the nervous system. Glia provide support and nourishment to neurons, synapses are the junctions between neurons where information is transmitted, and terminal buttons are the ends of the axons of neurons where neurotransmitters are released to signal the next neuron or target tissue.

Question 2

What is the correct order for information to pass through a neuron&#10;A)&#160;axon, soma, dendrite&#10;B)&#160;dendrite, axon, soma&#160;&#10;C)&#160;dendrite, soma, axon&#10;D)&#160;axon, dendrite, soma

Accepted Answer

The correct order for information to pass through a neuron is from the dendrites, which receive signals, to the soma or cell body, where the signals are integrated, and finally down the axon, which transmits the signals to other neurons or target tissues.

Question 3

What is the main function of dendrites&#10;A)&#160;to receive information&#10;B)&#160;to transmit information&#160;&#10;C)&#160;to support and insulate the neuron&#10;D)&#160;to release neurotransmitters

Accepted Answer

The main function of dendrites is to receive information from other neurons or sensory receptors and transmit it towards the cell body of the neuron.

Question 4

When a synapse is created,which of the following becomes possible&#10;A)&#160;destruction of dendrites&#10;B)&#160;blockage of neurotransmission&#160;&#10;C)&#160;increase in myelinization&#10;D)&#160;communication between two neurons

Accepted Answer

A synapse is a junction between two neurons that allows for communication between them. Therefore, the creation of a synapse makes communication between two neurons possible. Destruction of dendrites, blockage of neurotransmission, and increase in myelinization are not directly related to the creation of a synapse.

Question 5

What is the main function of the axon&#10;A)&#160;to break down neurotransmitters&#10;B)&#160;to transmit information&#160;&#10;C)&#160;to support and insulate the neuron&#10;D)&#160;to receive information

Accepted Answer

The main function of the axon is to transmit information from the cell body of the neuron to other cells, such as neurons or muscles.

Question 6

What are the chemicals that are secreted from the terminal buttons into the synapse&#10;A)&#160;action potentials&#10;B)&#160;hormones&#160;&#10;C)&#160;myelin&#10;D)&#160;neurotransmitters

Accepted Answer

Neurotransmitters are the chemicals that are secreted from the terminal buttons into the synapse. They transmit signals between neurons and are essential for communication within the nervous system.

Question 7

Which part of the neuron has branched extensions that are specialized to receive information&#10;A)&#160;Axons&#10;B)&#160;terminal buttons&#160;&#10;C)&#160;Somas&#10;D)&#160;Dendrites

Accepted Answer

Dendrites are the branched extensions of neurons that are specialized to receive information. They receive neurotransmitter signals from other neurons and transmit this information towards the cell body, which decides whether or not to generate an action potential.

Question 8

Where are terminal buttons located&#10;A)&#160;at the end of dendrites&#10;B)&#160;at the end of axons&#160;&#10;C)&#160;on the soma&#10;D)&#160;in the synaptic cleft

Accepted Answer

Terminal buttons, also called axon terminals, are located at the end of axons. They are responsible for releasing neurotransmitters into the synaptic cleft to communicate with other neurons.

Question 9

By what type of process are neural impulses transmitted through the nervous system&#10;A)&#160;a chemical process&#10;B)&#160;an electrical process&#160;&#10;C)&#160;a biological process&#10;D)&#160;an electrochemical process

Accepted Answer

Neural impulses are transmitted through the nervous system by an electrochemical process. Within the neurons, electrical impulses (action potentials) are generated and propagate down the axon. At the synapses between neurons, these electrical impulses trigger the release of neurotransmitters, which are chemicals that transmit the signal to the next neuron. This combination of electrical and chemical processes allows for rapid and precise communication within the nervous system.

Question 10

If you needed to send a message from the brain to your big toe,which cell would be used&#10;A)&#160;receptor&#10;B)&#160;neuron&#160;&#10;C)&#160;glial cell&#10;D)&#160;epithelial cell

Accepted Answer

Neurons are the cells that transmit messages, called nerve impulses, from the brain to various parts of the body, including the big toe. Receptors detect stimuli, glial cells provide support and insulation to neurons, and epithelial cells form the outer layer of skin and other tissues.
