Peripheral nervous system, PNS
_____ are electrical cables formed of bundles of axons. They link your central nervous system with your body sensory receptors, muscles, and plans.
Nerves
____ Carry messages from your body’s tissues and sensory receptors inward to your spinal cord and brain for processing.
Sensory neurons
____ carry instructions from your central nervous system out to your body’s muscles and glands.
Motor neurons
_____ with you and your brain and spinal cord communicate with one another and process information between the sensory inputs and motor outputs.
Inter-neurons
These are a part of the peripheral nervous system.
Somatic and autonomic
Monitor sensory input and triggers motor output, controlling your skeletal muscles. Also called the skeletal nervous system. Voluntary movement
Somatic nervous system
Controls your glands in the muscles of your internal organs, including those of your heart and digestive system. Out of reach of conscious control

If something alarms are challenges you, your ____ will arouse you, making you more alert, energetic, and ready for action.
Sympathetic nervous system
When the stress dies down, your ____ will calm you
Parasympathetic nervous system
Carry outgoing messages from the CNS to muscles and glands
Motor neurons
Carrie incoming messages from sensory receptors to the CNS
Sensory neurons
Communicate within the CNS and between incoming and outgoing messages
Interneurons
