Human Anatomy lecture quiz 11

The neurons that are responsible for integrating information by retrieving, processing, storing, and "deciding" how the body responds to stimuli are Sensory neurons Motor neurons Accessory neurons Correlation neurons Interneurons

Interneurons

The glial cell that defends the body against pathogens is the Astrocyte Ependymal cell Neurolemmocyte Microglial cell Oligodendrocyte

Microglial cell

A nerve impulse travels fastest along ________ axons of ______ diameter. Myelinated; small Unmyelinated; small Myelinated; large Unmyelinated; large None of the choices; axon diameter does not affect impulse conduction

Myelinated; large

The glial cell that myelinates and insulates axons in the peripheral nervous system is the Astrocyte Ependymal cell Neurolemmocyte Microglial cell Oligodendrocyte

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
