Opening of Na+ gates at the beginning of an action potential is caused by the activation of a receptor.

The primary motor cortex is part of the frontal lobe.

The integration center includes the brain, spinal cord and ganglia.

If you were to cut open a ventral root you would find

Myelin is formed by Oligodendrocytes in the PNS and Schwann cells in the CNS.

Neurotransmitters are only stored within vesicles in the axon terminal (synaptic knob) of a neuron.

Immediately after an action potential has peaked, which cellular gates are open?

Acetylcholine causes glycogen breakdown in the liver.

Saltatory conduction allows a nerve signal to travel down the axon by jumping from one node of Ranvier to the next node of Ranvier.

Oligodendrocytes are the most abundant of the glial cells.
