NSCI 225: Neurons overview | UPDATED Questions with 100% Verified
Answers
Question:
Dendrites
Answer:
Branchlike parts of a neuron receive input: signals come into the neuron
Question:
cell body (soma)
Answer:
contains nucleus; integrates incoming signals
Question:
Nucleus
Answer:
stores DNA
, Question:
Axon
Answer:
the extension of a neuron that sends output and carries the action potential
Question:
myelin sheath
Answer:
covers the axon of some neurons and helps speed neural impulses
Question:
Axon terminals
Answer:
branches at the end of the axon that release neurotransmitters
Question:
Synapse
Answer:
junction where neurotransmitters pass the signal to the next neurons
Question:
What does different shapes of neurons mean?
Answer:
they have different functions
Question:
One axon, many dendrites
Answer:
Neurons have many dendrites to collect input from multiple sources, but only one axon
leaving the cell body. The axon may branch later, but the action potential stays identical
in every branch.
