#14
Which of the following is NOT a function of the autonomic nervous system?
Regulating blood pressure
Controlling voluntary movements

#15
What is the significance of synaptic plasticity in the nervous system?
It refers to the ability of the nervous system to repair damaged neurons.
It describes changes in the synaptic strength between neurons, underlying learning and memory.
It is the process through which neurotransmitters are synthesized.
It signifies the number of synapses that are present in the nervous system at birth.
