What Structural type of neuron is this?  Unipolar

 

What Functional type is it mostly?

Sensory or Afferent

 

What direction does it go? PNS to CNS

 

Describe Processes; 1 process comes off cell body, splitting into two.

What type of neuroglia is this?  Ependymal cell

 

Where is it located Generally? CNS

 

Where is it located specifically? Lines ventricles of brain cavities and central canal of cord

 

Function:  assists in produdction and cirulation of CSF

 

 

 

 

Draw an Ependymal Cell

 

 

 

 

What type of neuroglia is this?  Astrocyte

 

Where is it located Generally? CNS

 

Where is it located specifically? In contact with neurons and capillaries

 

Function:  ahelps form blood-brain barrier

 

 

 

 

 

Draw an Astrocyte Cell

 

 

 

 

What type of neuroglia is this?  Microglial

 

Where is it located Generally? CNS

 

   

 

Function: defends against pathogens – macrophage-eats wastes

 

 

 

 

 

Draw a Microglia Cell

 

 

 

 

What type of neuroglia is this?  Oligodendrocyte

 

Where is it located Generally? CNS

 

Where is it located specifically? Extensions wrap around cns axons

 

Function:  myelinates and insulates CNS axons for fast impulse

 

 

 

 

 

Draw an Oligodendrocyte Cell

 

 

 

 

What type of neuroglia is this?  Satellite cell

 

Where is it located Generally? PNS

 

Where is it located specifically? in ganglia of PNS

 

Function: Protects and regulates nutrients for cell bodies in ganglia

 

 

 

 

 

Draw a Satellite Cell

 

 

 

 

What type of neuroglia is this?  Neurolemmocytes = Schwann

 

Where is it located Generally? PNS

 

Where is it located specifically?wrapped around axon in PNS

 

Function:  Myelinates and insultes PNS axons for fast impulse
