Neurolemmocyte
The glial cell that myelinates and insulates axons within the CNS is the Astrocyte Ependymal cell Neurolemmocyte Microglial cell Oligodendrocyte
Oligodendrocyte
The connective tissue wrapping that surrounds bundles (fascicles) of axons is the Epineurium Endoneurium Perineurium Endosteum Periosteum
Perineurium
Billions of CNS interneurons are grouped in complex patterns called neuronal Networks Complexes Pools Meshes Webs
Pools
The glial cell that protects neuron cell bodies located within ganglia is the Satellite cell Ependymal cell Neurolemmocyte Astrocyte Oligodendrocyte
Satellite cell
Which does not belong to the peripheral nervous system? Ganglion Cranial nerve Spinal cord Peripheral nerve Spinal nerve
Spinal cord
Glial cells differ from neurons in that they Are larger and capable of meiosis Are smaller and capable of mitosis Are found only in the CNS Are found only in the PNS Transmit nerve impulses much more slowly
Are smaller and capable of mitosis
The glial cell that helps to form the blood-brain barrier is the Astrocyte Ependymal cell Neurolemmocyte Microglial cell Oligodendrocyte
Astrocyte
The most abundant glial cell in the CNS is the Astrocyte Ependymal cell Neurolemmocyte Microglial cell Oligodendrocyte
Astrocyte
You walk into a restaurant and amidst the sights, sounds, and smells of food preparation, you notice that you have begun to salivate. This is evidence that a particular neuronal circuit has been activated. Which one? Converging Diverging Reverberating Parallel after-discharge None of the choices is correct
Converging
The glial cell that helps to form cerebrospinal fluid is the Astrocyte Ependymal cell Neurolemmocyte Microglial cell Oligodendrocyte
Ependymal cell
The connective tissue wrappings of a nerve, beginning at the outermost layer, are Perineurium → epineurium→ endoneurium Perineurium → endoneurium→ epineurium Epineurium → perineurium→ endoneurium Epineurium → endoneurium→ perineurium Endoneurium → perineurium→ epineurium
Epineurium → perineurium→ endoneurium
All axons in the CNS and PNS are myelinated. True False
False
Regeneration of axons occurs more readily in the CNS than in the PNS. True False
False
The glossy-white appearance of most axons is due to The high lipid content of the myelin sheath Their proximity to light-reflecting cartilage Their proximity to white bone The white color of the perivascular feet The covering of ependymal cells
The high lipid content of the myelin sheath
Saltatory conduction of a nerve impulse occurs only along myelinated axons. True False
True
Continuous conduction of a nerve impulse occurs only along Myelinated axons Dendrites Unmyelinated axons Axons in the PNS Axons in the CNS
Unmyelinated axons
