5 Matching questions
- Myelin Sheath
- larger the nerve the faster the conduction velocity, myelinated nerves are faster than unmyelinated nerves
- Efferent Neuron
- Satellite Cells
- a insulates the nerve fibers
- b K+ moves out of the cell causing the membrane potential to move in a negative direction.
- c the PNS glial cell that surrounds the dorsal root ganglion neurons
- d a neuron that conducts impulses away form the CNS to muscles and glands; motor neurons
- e What is the relationship between myelination and size and conduction velocity?
5 Multiple choice questions
- Difference in electrical charge across the plasma membrane. The membrane would be POLARIZED.
- one single process leading away from the soma; afferent neurons are unipolar
- collection of nerve cell bodies found outside the CNS
- carry signals toward the CNS from the body periphery; sensory neurons
- surrounds each nerve fiber

Nerve impulse → Another name for the action potential in neurons.
Neurofibril → specialized supporting cells in the CNS
Nuclei → a bundle of nerve processes
