    · Sensory,
    Motor & Inter neurons
    · Processes
    signals
    · Sends
    signals to other neurons, muscles or organs
    The Neuron
  2. The brain contains _____ neurons
    100 billion
  3. Sensory neurons respond to input from the _____
    Sense organs
  4. Motor neurons send signals to ______ to control ______
    muscles; movement
  5. _______ stand between the neurons that register "whats out there" and those that control movement
    Interneuron
  6. A set of neurons that affect one another
    Brain Circuit
  7. ________receive information from other neurons or the environment
    Dendrites
  8. __________ controls the cell’s metabolic activities and integrates inputs
    Cell Body
  9. ______ release chemicals into the space between neurons when their neuron has
    been triggered
    Terminal buttons
  10. ______ conducts the nerve impulse away from the
    cell body
    Axon
  11. Step 1:

    · The
    action potential reaches the end of the axon

    Step 2:

    · Synaptic
    vesicles release neurotransmitters to the synaptic cleft

    Step 3:

    · Neurotransmitters
    blind to receptors and the action potential is transmitted
    Neurotransmitters and Neuromodulators:
  12. Traditional view

    · Fills
    the gaps between neurons

    · Supports
    and feeds neurons

    · Cleans
    up dead neurons and extra neurotransmitters
    Glial Cells
  13. -Top, rear of the brain
    -Functions include:
    · Attention
    · Spatial location
    · Somatosensory processing
    -Unilateral visual neglect
    The Parietal Lobes:
  14. in the front of the brain; animalistic like
    function
    Forebrain
  15. region that receives sensory input from motor
    systems and helps us pay attention; aids in sleep control; if badly damaged the
    human will die even if outer parts are undamaged
    Thalamus
  16. sits under the thalamus; helps control
    many body functions i.e.; body temp, heart-rate, sexual behavior, regulating
    hormones, eating
    Hypothalamus
  17. allows people to store info in their
    memory banks; role is to help us retain facts
    Hippocampus
  18. near the hippocampus, helps us regulate our
    emotions
    Amygdala
  19. involved in planning and producing
    movement
    Basal Ganglia:
  20. large structure at the base of the brain;
    physical coordination, estimating time, ability to stand, keep an upright
    posture, ability to pay attention
    Cerebellum
