nervous system
Nervous System
  • Central Nervous System (CNS)- brain and spinal chord
  • Peripheral Nervous System (PNS)- all nerves extending from and going to the CNS
  • Composed of over 100 billion neurons
neurotransmitters
Neurotransmitters
  • Are required along with vesicles to transmit a nerve impulse from one neuron to another over the synapse.
classes of neurons
Classes of Neurons
  • Afferent- do not have dendrites: transmit impulses from specialized structures to the Central Nervous System
  • Efferent- conduct electrical signals from the CNS to muscle or glad cells
  • Inter- reside entirely within the CNS and make up about 99% of all neurons
neuroscience terminology
Neuroscience Terminology
  • Nerve- bundle of axons in the PNS
  • Pathway- bundle of axons in the CNS
  • Commissure- a collection of nerve fibers linking the left and right halves of the CNS
  • Nuclei- cell bodies linked together in the CNS
  • Ganglia- cell bodies linked together in the PNS
