3. Myelin sheath increases the speed of impulse along an axon. - False

4. Spinal cord is the extension of cerebellum. - True

5. Cerebellum coordinates voluntary actions. - True

6. The cerebrum maintains balance of the body.​ - True

Explanation:

1. The transfer of the electrical impulse takes place from one neuron to another neuron at a junction called synapses.

2. The motor nerve conduct impulses to muscles from the brain and the spinal cord​.

3. A myelin sheath decreases the capacitance of the neuron in the area it covers.

4. The spinal cord is an extension of the central nervous system (CNS), which consists of the brain and spinal cord.

5. The cerebellum is a major structure of the hindbrain that is located near the brainstem. This part of the brain is responsible for coordinating voluntary movements
