Structure And Function Of Neurons Flashcards
What is do dendrites do?
Where the neurotransmitter receptors are found. Once the receptor and neurotransmitter bind, this causes a new electrical impulse to occur
Dendrites - Where the neurotransmitter …. are found. Once the receptor and neurotransmitter …., this causes a new …. to occur
Receptors
Bund
Electrical impulse
What’s does a cell body do?
Includes the nucleus which contains the genetic material of the cell
Cell body - Includes the …. which contains the …. of the cell
Nucleus
Genetic material
In dendrites when the receptor and neurotransmitters bind it causes what?
New electrical impulses to occur
What’s found in the cell body of a neuron?
Nucleus
What does the nucleus contain?
Genetic material
What does the axon do?
Sends nerve impulse through the neuron to transmit a message to the next neuron
Axon - Sends …. through the neuron to …. a ….. to the next ….
Nerve impulses
Transmit
Message
Neuron
What does the axon send through the neuron to transmit a message?
Nerve impulses
What does the nodes of ranvier do?
Speeded up the transmission of the impulse by forcing it to jump across the gaps along the axon
Nodes of ranvier - Speeded up the transmission of the …. by forcing it to …. across the …. along the ….
Impulses
Jump
Gaps
Axon
What does the myelin sheath do?
Protects the axon and helps to speed up transmission of the message
How does the nodes of ranvier speed up transmission of the impulse?
By forcing it to jump across the gaps along the axon
What does the myelin sheath protect?
Axon
The myelin sheath speeds up what?
Transmission of the message
What does the terminal button do?
The end of the neuron and they send the information through to the next neuron, through the release of neurotransmitters
Terminal button - The …. of the neuron and they send the …. through to the next neuron, through the ….. of …..
End
Information
Release
Neurotransmitters
Where on the neuron is the terminal button?
End of the neuron
The terminal button sends information where?
Through to the next neuron through the release ur the neurotransmitters
What’s the order of the structure of the neuron?
Dendrites
Cell body
Axon
Nodes of ranvier
Myelin sheath
Terminal button
Where are the dendrites?
Attached to cell body
Where’s the axon?
The long part connecting cell body to terminal button
Where’s the nodes of ranvier?
The gap between each myelin sheath
