Neurons Flashcards
What is the function of dendrites?
Dendrites receive signals from other neurons.
What part of the neuron contains the nucleus?
The cell body (soma) contains the nucleus.
What does the axon do?
The axon carries electrical signals to the axon terminals.
How does the myelin sheath affect signal transmission
The myelin sheath speeds up signal transmission.
What are Nodes of Ranvier, and why are they important?
Nodes of Ranvier allow the signal to “jump,” making transmission faster.
What happens at the axon terminals?
At the axon terminals, neurotransmitters are released.
What is released into the synapse to pass a signal to the next cell?
Neurotransmitters are released into the synapse.
Which part of the neuron is responsible for receiving signals?
Dendrites are responsible for receiving signals.
How do motor neurons differ from sensory neurons
Motor neurons send signals to muscles or glands, while sensory neurons carry signals to the brain.
What triggers the release of neurotransmitters
An action potential triggers neurotransmitter release.
