    The part of the neuron labelled

    The part of the neuron labelled "D" is"

    • An axon

    • A dendrite

    • The myelin sheath

    • The cell body

    Correct Answer
    A. A dendrite
    Explanation
    The part of the neuron labelled "D" is a dendrite. Dendrites are the branch-like structures that receive signals from other neurons and transmit them to the cell body. They play a crucial role in the communication between neurons and are responsible for integrating and processing incoming information.

    The roll of the axon is:  - ProProfs

    The roll of the axon is: 

    • To receive messages

    • To send messages

    Correct Answer
    A. To send messages
    Explanation
    The axon is responsible for transmitting electrical signals, known as action potentials, away from the cell body of a neuron. These messages are sent to other neurons, muscles, or glands in the body. The axon is specialized for rapid and efficient conduction of these signals, as it is long and covered in a fatty substance called myelin. Therefore, the correct answer is "to send messages."

    The part of the neuron labelled

    The part of the neuron labelled "B" is :

    • An axon

    • A dendrtite

    • The myelin sheath

    • The cell body

    Correct Answer
    A. An axon
    Explanation
    The part of the neuron labelled "B" is an axon. An axon is a long, slender projection of a neuron that carries electrical impulses away from the cell body to other neurons, muscles, or glands. It is responsible for transmitting information from the cell body to other parts of the nervous system.

    The part of the neuron labelled

    The part of the neuron labelled "C" is:

    • An axon

    • A dendrite

    • The myelin sheath

    • The cell body

    Correct Answer
    A. The cell body
    Explanation
    The part of the neuron labelled "C" is the cell body. The cell body, also known as the soma, is the main part of the neuron that contains the nucleus and other organelles. It is responsible for maintaining the overall functioning of the neuron and integrating incoming signals from dendrites. The cell body also plays a role in protein synthesis and energy production to support the neuron's activities.

    Neurotransmitters are:

    • The outer covering of the dendrite

    • Chemicals that go between nerve cells

    • The structure that causes new learning to occur

    Correct Answer
    A. Chemicals that go between nerve cells
    Explanation
    Neurotransmitters are chemicals that go between nerve cells. They are responsible for transmitting signals from one nerve cell to another, allowing for communication within the nervous system. These chemicals are released from the axon of one nerve cell and bind to receptors on the dendrites of another nerve cell, triggering a response. Neurotransmitters play a crucial role in various physiological processes such as movement, cognition, and emotions.

    The part of the neuron labelled

    The part of the neuron labelled "A" is:

    • An axon

    • A dendrite

    • The myelin sheath

    • The cell body

    Correct Answer
    A. The myelin sheath
    Explanation
    The myelin sheath is a protective covering that surrounds the axon of a neuron. It is made up of fatty substances and acts as an insulator, allowing for faster transmission of electrical signals along the axon. Option A, axon, is incorrect as the axon is the long fiber that extends from the cell body and transmits signals away from the neuron. Option B, dendrite, is incorrect as dendrites receive signals from other neurons. Option D, the cell body, is incorrect as it contains the nucleus and other organelles but does not form the myelin sheath.

    One way for new learning to occur:

    • The synapses have to become closer together

    • The cell body has to become wider

    • New dendrites sprout every time you learn something new

    • The myelin sheath has to thin out

    Correct Answer
    A. New dendrites sprout every time you learn something new
    Explanation
    When we learn something new, new dendrites (branch-like extensions of neurons) sprout. This allows the neurons to form new connections and create new pathways for information to flow through the brain. This process is known as synaptic plasticity and is essential for the formation of new memories and the acquisition of new skills. The other options mentioned in the question, such as synapses becoming closer together or the cell body becoming wider, do not accurately describe the process of new learning.

    Rate this question:

  • 9. 

    A synapse is:

    • A special chemical that goes between neurons

    • The shorter part of the neuron, next to the cell body

    • The longer part of the neuron, extending out from the cell body

    • A gap between two neurons

    Correct Answer
    A. A gap between two neurons
    Explanation
    A synapse is a gap between two neurons where information is transmitted from one neuron to another. It is a specialized junction that allows for communication between neurons through the release and reception of chemical messengers called neurotransmitters.
