This type of neuron has many dendrites and one axon and is the most common in the brain and spinal cord.
multipolar neuron
This type of neuroglia forms the myelin sheath in the central nervous system (CNS)
oligodendrocytes
These neurons transmit impulses from sensory receptors to the CNS
sensory (afferent) neurons
On a microscope slide of a spinal cord smear, these darkly stained small nuclei found near neurons are most likely from these supporting cells
neuroglia
This part of the neuron conducts impulses away from the cell body.
the axon
These star-shaped neuroglial cells support neurons and blood vessels and help maintain the blood-brain barrier.
astrocytes
This is the connective tissue layer surrounding a fascicle (bundle) of nerve fibers
perineurium
In the longitudinal section of a nerve, this narrow gap between Schwann cells helps increase the speed of impulse conduction
the node of Ranvier
These are threadlike structures that extend into the axon and help maintain cell shape.
neurofibrils
In the peripheral nervous system, this cell forms myelin and contains the neurilemma, which is vital for nerve regeneration.
Schwann cells
This connective tissue layer wraps around each individual nerve fiber and its Schwann cell.
endoneurium
When viewing a posterior root ganglion under the microscope, these large, round structures grouped together are the cell bodies of these neurons
sensory (afferent) neurons
