Nervous system (http://www.youtube.com/watch?v=qPix_X-9t7E)
- All thoughts, actions and emotions:
- Integration
- Nervous system processes the sensory input and decides what should be
done about it
Organization
- Central nervous system (CNS)
- Peripheral nervous system (PNS)
Central nervous system
- Brain and spinal cord
- The main control center
- Decides to take action and gives the order to your muscles
, Peripheral nervous system
- All nerves that from brain and spine that allow the CNS to communicate with
the rest of the body
- Job: communication
- Works in both directions
- Sensory division/ afferent division: picks up sensory input and
sends it to the brain
- Motor division/ efferent division: sends information from the brain to
the muscles and glands
- Includes the somatic/ voluntary nervous system: rules your
skeletal muscle movement
- And autonomic/ involuntary nervous system: keeps your
heart beating, lungs breathing and stomach churning
- Autonomic nervous system
- Sympathetic division: gets the body into action (like moving)
- Parasympathetic division: relaxed the body and calms it down
- Neurons/ nerve cells
- Respond to stimulate and transmit signals
- Are surrounded by glial cells
- Glial cell types in the central nervous system
- Provide support, nutrition, insulation and help with signal transmission in the
nervous system
- About half of the mass of your brain
- Star-shaped astrocytes
- Exchange of materials between neurons and capillaries
- Anker neurons to their blood supply
- Protective microglial cells
- Immune defense against invading microorganisms
- Smaller
- Ependymal cells
- Create, secrete and circulate cerebrospinal fluid
- Oligodendrocytes
