Clusters of neural cell bodies in the CNS are called | Nuclei |
Tracts are to nuclei as nerves are to | Ganglia |
CNS is to PNS as oligodendrocytes are to | Schwann cells |
In the CNS, axons are myelinated by | Oligodendrocytes |
Myelination | Increases the speed of axonal conduction |
PNS is to CNS as Schwann cells are to | Oligodendrocytes |
Chemical communication among mammalian neurons often occurs | Across synapses |
The soma is | The cell body |
Many multipolar neurons have a long process emanating from the cell body. This long process is | An axon |
The cone-shaped structure at the boundary between the cell body and axon of a multipolar neuron is the | Axon hillock |
Synaptic vesicles tend to be most prevalent in the | Buttons |
Most of a neuron’s DNA is in its | Nucleus |
The particular glial cells that engulf cellular debris and trigger inflammation are | Microglia |
The largest glial cells are | Astrocytes |
The Golgi stain colours neurons | Black |
The best thing about the Golgi stain is that it | Does not stain many neurons |
The discovery of the Golgi stain A) was accidental B) was one of the major early breakthroughs in the study of the nervous system C) occurred in 1995 | Both A and B |
The first neural stain revealed the silhouettes of a few neurons on a slide; it is | The Golgi stain |
The first neural stain that permitted neuroanstomists to view some aspects of the inner structure of a neuron was | The Nissl stain |
Nissl stains (e.g., cresyl violet) are frequently used to | Determine the general distribution of cell bodies in the nervous system |
The fine inner details of neuron structure can be studied best | By electron microscopy |
The main advantage of the scanning electron microscope over the conventional electron microscope is that it | Produces three-dimensional images |
To locate the terminals of axons that project from a particular brain structure, an investigator would employ | An anterograde tracing technique |
The back of your head is | Posterior |
The top of a dog’s head is | Dorsal |
