A nerve that contains only efferent fibers is called a(n)

The threshold potential for neurons is -55mV.

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

A neuron that has myelin and a large nerve fiber would transmit a signal faster than a neuron with myelin and a small nerve fiber.

Acetylcholine causes glycogen breakdown in the liver.

The optic nerve provides sensory and motor function.

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

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

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

Action potentials only occur on nerve fibers.
