2 parts of nervous tissue Glia Cells, and neurons.
Glia cell are support cells of the brain
astrocytes, microglia, oligodendrocytes
Astrocytes makes the blood brain barrier. Connects to blood
vessels and acts as the gate keeper. Does allot with
metabolism, mostly of medication
Microglia immune cells of the brain. Migrate to the area of
injury, it covers it and cleans it up. It does not have
allot of T or B cells.
, Oligodendrocytes secretes allot of myelin. It is important for the
neuron. Actually wraps around portions of the
neuron.
Myelin increases the speed of the neuron. It is the white
matter of the brain and the spinal cord.
Neurons and Glia can grow back but they grow back very slowly.
neuron information only travels in one direction. That way there is no traffic jams or
mixed signals.
Dendrites where the information comes in to the neuron
Cell Body houses the nucleus and other cell structures.
Receives signal from the dendrites.
Axon gets information from the cell body
Axon Terminals Get information from the axon. Is where we release
all of the neuron transmitters.
Myelin Not all neurons have ______ but those that do move
information quickly
Afferent Neurons are sensory neurons. Carries information to the
Central nervous system.
Interneurons makes connections within the central nervous
system.
Efferent Neurons. Motor neurons. Carry information away from the
