Items needed to make neuron: What Structural type of neuron is this? Unipolar 1) Cell body=soma= Perikaryon 2) Hillock 3) Axon 4) Dendrite 5) Myeline sheath 6) Node of Ranvier 7) Nucleus 8) Nucleolus 9) Nissl granules What Functional type is it mostly? Sensory or Afferent What direction does it go? PNS to CNS Draw a Neuron What Structural type of neuron is this? Multipolar Describe Processes; 1 process comes off cell body, splitting into two. Draw an Unipolar Neuron What Structural type of neuron is this? Bipolar What Functional Type is it? Special sense neuron What Functional type is it mostly? Motor or Efferent, Can also be interneuron in the CNS Where is it found? Part of the ear and eyes. Found in embryos What direction does it go? Motor-CNS to PNS, interneuron-CNS Describe Processes; 2 process. 1 dendrite, 1 axon. Describe Processes; 1 Axon, many dendrites Draw a Multipolar Neuron Draw a Bipolar Neuron What type of neuroglia is this? Ependymal cell What type of neuroglia is this? Microglial Where is it located Generally? CNS 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 Function: defends against pathogens – macrophage-eats wastes Draw an Ependymal Cell Draw a Microglia Cell What type of neuroglia is this? Astrocyte What type of neuroglia is this? Oligodendrocyte Where is it located Generally? CNS Where is it located Generally? CNS Where is it located specifically? In contact with neurons and capillaries Where is it located specifically? Extensions wrap around cns axons Function: ahelps form blood-brain barrier Draw an Astrocyte Cell 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?wrapp ed around axon in PNS Function: Myelinates and insultes PNS axons for fast impulse Draw a Schwann Cell
