Marsupials have nervous systems similar to many mammals, with the exception of a few characteristics. Marsupials have a very complex nervous system. Their nervous system works with the senses to transmit information to the brain, a process that takes less than one-hundredth of a second. Their brains are wired to react quickly in order to protect themselves from danger and to allow it to assess immediate environment easily. Marsupials, just like humans, have nerve endings spread throughout their whole bodies that allow them to respond to stimuli.
Their nervous system is composed of neurons and glial cells. In the central nervous system, which is the brain and spinal cord, the neurons have dendrites which carry bioelectrical impulses to the cell body. The second group of cells are the glial cells. These type of cells are located in the central nervous system and the peripheral nervous system, however, the glial cells include astrocytes, oligodendrocytes, and schwann cells. Astrocytes help transport nutrients to neurons. While schwann cells and oligodendrocytes help produce collagen and other extracellular molecules which form a cuff of basal lamina around each peripheral nerve axon.
