Explanation / Answer
1.Option A)
The space between two neurons in called synapse.A neuron mainly consists of cell body with branch like structures called dendrites which receive signals from other neurons and a tail like structure called axon which transmits the information through the cell.
2.Option D)
Action potentials are the signals that are conducted by the axon.These occur only when the dendrites receive signals of a certain threshold. Resting potential is the state of the neuron before the action potential.
3.Option D)
Corpus callosum is the fibrous bundle of nerves that connects the two hemispheres.
4.Option C)
Our cerebellum is responsible for coordinated movements.
