• main processing center for the entire nervous system

  CENTRAL NERVOUS SYSTEM
• connects all your body parts and transmits signals from one part to another

  NERVOUS SYSTEM
• two main organs of central nervous system

  brain and spinal cord
• organ located in the skull that organizes and distributes information for the body

  brain
• three main parts of the brain

  cerebrum, cerebellum, brain stem
• controls activity and thoughts

  cerebrum
• controls posture, balance, coordination

  cerebellum
• controls automatic functions (breathing, digestion, etc.)

  brain stem
• channel for signals between brain and the rest of the body

  spinal cord
• connects cns to the organs and limbs

  peripheral nervous system
• two parts of pns

  somatic and autonomic
• voluntary control of body

  somatic nervous system
• involuntary control of body

  autonomic nervous system
• process and analyzes information

  cns
• follows the command of cns

  pns
• basic unit of the nervous system; cells that have the ability to carry signals

  nerve cells or neurons
• carry signals towards cell body

  dendrites
• carry signals from the cell body

  axons
• small gap at the end of a neuron

  synapse
• composed of glands that secrete different types of hormones

  endocrine system
• stimulates growth and controls functions of other glands

  pituitary
• releases GnRH


  hypothalamus
• hormones that pituitary releases

  FSH and LH
