Dendrites
Axon hillock
Axon terminal branches
Node of Ranvier
The Myelin sheath is derived from the
Microglia
Astrocytes
Schwann cells
Oligodendrocytes
About glial cells, which is INCORRECT:
Satellite cells have the same function as astrocytes.
Schwann cells encapsulate multiple segments, while oligodendrocytes encapsulate only one segment.
Microglial cells support neurons and phagocytize bacterial cells and other debris.
Astrocytes contribute to the blood-brain barrier.
Which of the following statements is false?
The soma is the cell body of a nerve cell.
Myelin sheath provides an insulating layer to the dendrites
Axons carry the signal from the soma to the target.
Dendrites carry the signal to the soma.
Motor neurons and interneurons are _______ neurons.
pseudo-unipolar
bipolar
multipolar
afferent
Clusters of neuron cell bodies within the peripheral nervous system are
ganglia
fascicles
nuclei
laminae
Cells found in the choroid plexuses that secrete cerebrospinal fluid are
astrocytes
microglia
ependymal cells
oligodendrocytes
Schwann cells
Action potentials are conducted more rapidly
in small-diameter axons than in large-diameter axons
in unmyelinated axons than in myelinated axons
along axons that have nodes of Ranvier
All of these are correct.
Most of the neurons of our body are
Unipolar
Bipolar
Pseudounipolar
Multipolar
Which type of cell would be present in large numbers if there were a bacterial infection in the brain?
astrocyte
oligodendrocytes
microglia cells
ependymal cells
Astrocytes
form a living barrier between capillaries and neurons
support and brace the neurons and anchor them to their nutrient supply lines
play a role in making exchanges between the capillaries and neurons
All of the above
Satellite cells, except
similar function as astrocyte
found in surrounding sensory and autonomic ganglia in the CNS
regulate the neuronal environment
none of the above
These glial cells are thought to be derived from bone marrow, enter the central nervous system early in development, and reside within the central nervous system throughout the lifespan.
