, Afferent nerve fibers usually dorsal
Efferent nerve fibers transverse cord where?
Neurons communicate with each other, and specialized synapses
membranes on effector organs, across spaces called
don't come in contact with each other
transmitted across by chemical and electrical conduction
secretion of Its
afferent pathways are sensory
efferent pathways are motor
Oligodendrocytes Type of glial cell in the CNS that wrap axons in a myelin sheath.
Nodes of Ranvier Gaps in the myelin sheath to which voltage-gated sodium channels are
confined.
induces clustering of sodium channels at the nodes
What type of cell is the counterpart to
oligodendrocytes what does it deposit where?
Schwann cells Type of glia in the PNS, Supporting cells of the peripheral nervous system
responsible for the formation of myelin.
so oligodendrocytes where? Schwann where? oligodendrocytes- CNS
Schwann- PNS
Schwann Cells and oligodendrocytes form the myelin the white matter of the system which is then differentiated from the grey
sheath that covers nervous system structure to unmyelinated matter
collectively form:
Grey or white matter is myelinated? white matter
