Axon
Myelin Sheath
Nodes of Ranvier
Sensory Neurons (afferent neurons)
Motor Neurons (efferent neurons)
Central Nervous System
Peripheral Nervous System
Cerebrospinal Fluid
excitable cells that respond to stimuli by conducting impulses to transmit signals
supportive cells that provide nutrition, insulation, and help with signal transmission
the life support containing the nucleus and most organelles
the main receptor of signals
generates and transmits nerve impulses
covers long axons to protect and electrically insulate them to increase the speed of nerve impulse transmission
unmyelinated gaps in the myelin sheath that aid in increasing the velocity of nerve signal conduction
transmit info from sensory receptors to CNS
transport info from CNS to rest of the body
brain and spinal cord
communication system between the CNS and the rest of the body
central nervous system, brain, and spinal cord
