Biological Perspective Quiz 2 - Neurotransmitters
Biological Perspective Quiz 2 focuses on neurotransmitters, exploring their roles and mechanisms in neuron communication. It assesses understanding of axon structures, synaptic processes, and the impacts of neurotransmitters like acetylcholine on functions such as memory and muscle contractions.

What is the yellow part shown on the diagram below
- A.
Cell body
- B.
Dendrites
- C.
Nucleus
- D.
Axon
Correct Answer
D. AxonExplanation
The yellow part shown on the diagram is the axon. The axon is a long, slender projection of a nerve cell that carries electrical impulses away from the cell body to other cells. It is responsible for transmitting signals to other neurons, muscles, or glands. Axons are covered by a fatty substance called myelin, which helps to insulate and speed up the transmission of electrical signals.Rate this question:

List the following in order of occurance A. Action potential travels along axon of sending neuron B. The neurotransmitter must fit perfectly into the receptor C. Synaptic transmission occurs when the action potential causes neurotransmitters to be released by the synaptic vesicles in the axon terminals D. The neurotransmitters cross the synaptic gap and bind with the correctly shaped receptor sites on the receiving neuron.
- A.
ACDB
- B.
ACDC
- C.
ABBA
- D.
ADCB
Correct Answer
A. ACDBExplanation
The correct order of occurrence is as follows: A. Action potential travels along axon of sending neuron, C. Synaptic transmission occurs when the action potential causes neurotransmitters to be released by the synaptic vesicles in the axon terminals, D. The neurotransmitters cross the synaptic gap and bind with the correctly shaped receptor sites on the receiving neuron, and finally B. The neurotransmitter must fit perfectly into the receptor.Rate this question:

The process by which neurotransmitter molecules detach from a postsynaptic neuron are reabsorbed by a pre-synaptic neuron so they can be recycled and used again.
- A.
Axon terminals
- B.
Synaptic transmission
- C.
Reuptake
- D.
Neurotransmitters
Correct Answer
C. ReuptakeExplanation
Reuptake is the process by which neurotransmitter molecules detach from a postsynaptic neuron and are reabsorbed by a pre-synaptic neuron. This allows the neurotransmitters to be recycled and used again in synaptic transmission.Rate this question:

What does acetylcholine do?
- A.
Emotional states, sleep
- B.
Physical arousal, learning, memory
- C.
Learning, memory, muscle contractions
- D.
Movement, thought processes, rewarding sensations
Correct Answer
C. Learning, memory, muscle contractionsExplanation
Acetylcholine is a neurotransmitter that plays a crucial role in various physiological processes. It is involved in learning and memory by facilitating the communication between neurons in the brain, which aids in the formation and retrieval of memories. Acetylcholine also plays a role in muscle contractions by transmitting signals from motor neurons to muscle fibers, allowing for voluntary movement and control. Therefore, the correct answer is "learning, memory, muscle contractions."Rate this question:

Which one of these effects are can drugs not do?
- A.
Drugs can mimic the neurotransmitter
- B.
Drugs can block the receptor site on the receiving neuron
- C.
Drugs can block he reuptake of the neurotransmitter
- D.
None of the above
Correct Answer
D. None of the aboveExplanation
Drugs can mimic neurotransmitters, block receptor sites on receiving neurons, and block the reuptake of neurotransmitters. Therefore, none of the effects listed can be excluded as something drugs cannot do.Rate this question:
