An anticholinergic drug is considered parasympatholytic.

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

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

The phrenic nerve emerges from the sacral plexus.

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

Which cranial nerve stimulates neck and shoulder movements?

Norepinephrine binds to muscarinic receptors.

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

During an action potential, Sodium exits the cell causing the membrane potential to become more negative.

The most rapid conduction of an impulse along an axon occurs on a fiber that is
