phagocytosis of debris (dead cells, bacteria, etc)
form myelin around axons in the CNS
support the neurons; may serve nutritive function and help regulate the chemical environment on the neurons
line cavities of the brain (and spinal cord); aid in circulation on cerebrospinal fluid
what is the PNS glial cell that forms myelin?
what is the PNS glial cell that surrounds dorsal root ganglion neurons?
the brain and spinal cord colletively
central nervous system
speicalized supporting cells in the CNS
junction or point of the close contact between neurons
a bundle of nerve processes inside the CNS
neuron serving as part of the conduction pathway between sensory and motor neurons
ganglia and spinal and crainal nerves
peripheral nervous system
collection of nerve cell bodies found outside the CNS
neuron that conducts impulses away from the CNS to muscles and glands
neuron that conducts impulses toward the CNS from the body periphery
chemical released by neurons that stimulate or inhibit other neurons or effectors
region of the cell body from which the axon originates
receptive region of a neuron
insulates the nerve fibers
site of the nucleus and is the most important metabolic a area
neuronal cell body
maybe involved in the transport of substances within the neuron
essentially rough endoplasmic reticulum, important metabolically
impulse generator and transmitter
what substance is found in synaptic vesicles of the axon terminal?
what neuron types are unipolar?
what neuron is most likely multipolar?
motor neuron, interneuron
surrounds a bundle of axons
surrounds all of the axons contributing to a nerve
