Answers)
unipolar neurons Answer: transfer electrical impulses fastest & at
greatest distances
-receptive pole & output zone
-sensory nervous system
EX: Pain

TERMINALS
where info is transferred to other cells
dendrites Answer: BEGINNING of neuron
-CONVERGE to make 1 signal
cell body Answer: integrates incoming signals & generates outgoing
signal to axon
axon Answer: passes electrical signals to dendrites of another cell or to
an effector cell
-thicker = faster
-1 axon/neuron
glial cells Answer: Different types
1. astrocytes
2. microglia
3. ependymal
4. oligodendryocytes

astrocytes Answer: GLIAL CELL
supportive cells in brain that fills in spaces
-store, absorb, release chemicals
-most numerous glial cell in CNS
microglia Answer: GLIAL CELL
clean up dying neurons & glia
-PHAGOCYTES
-brain & spinal cord only
ependymal cells Answer: GLIAL CELL
PHASE 1: guiding embryonic cells during development
PHASE 2: lining ventricles & secreting CSF
-VENTRICULAR SYSTEM
oligodendrocytes Answer: GLIAL CELL
Wraps around many axons in order to coat them with myelin sheaths
in CNS
