Question

question 11
the ______ of a presynaptic neuron associates with the dendrite of a postsynaptic neuron.
synapse
axon terminal
axon
cell body
dendrite

question 12
this is the site of communication between neurons.
synapse
axon terminal
axon
cell body
dendrite

question 13
neurons have
complete regeneration capacity.
no regeneration capacity.
very limited capacity to repair themselves.
none of the above.

Explanation:

• Question 11: The axon terminal of a presynaptic neuron associates with the dendrite of a postsynaptic neuron. It is the end - point from which neurotransmitters are released towards the postsynaptic neuron.
• Question 12: The synapse is the site of communication between neurons. It is the junction where an axon terminal of one neuron interacts with a dendrite or cell body of another neuron.
• Question 13: Neurons have a very limited capacity to repair themselves. Unlike some other cell types, they do not have a high regenerative ability.

Answer:

• Question 11: B. axon terminal
• Question 12: A. synapse
• Question 13: C. very limited capacity to repair themselves
