Slide of Multipolar Neuron – pg. 79 Nuclei of Neuroglial or Glial Cells Cell Body of a Multipolar Neuron

Neuron: a single nerve cell (nerve fiber) Figure 8 Page 84 of lab book Neuron: a single nerve cell (nerve fiber) Nerve: an organ comprised of hundreds to thousands of neurons wrapped in connective tissue.

Cross Section of a Nerve Note: epineurium, perineurium, nerve fasicles A buncle of neurons (nerve fibers) Epineurium: Connective tissue surrounding the entire nerve organ Perineurium: Connective tissue surrounding the one nerve fasicle

Between 2 Nerve Fascicles Note: perineurium, endoneurium, myelinated axons Connective tissue surrounding the one nerve fasicle Endoneurium: Connective tissue in between the myelinated axons Axon (dot) Note the myelin sheath (white area surrounding the dot)
