  1. what is the neuron made up of?
    two cell types Neurons, glid cells
  2. What is a neuron?
    Responsible for information transmittion throughout the nervous system. Receive, send, and intigrate within brain and rest of nervous system
  3. What is Glial cells?
    cells in the nervous system that compromise the support system for the nerves (Take away the waste products of neurons, neep neurons chemical environment stable and insulate then allowing neurons to do their work more efficiently
  4. What are the three components of a neuron?
    The cell body, dendrites, and axon
  5. What is the function of a cell body?
    contains the neucleous and other biological machinery to keep the cell alive and that decides wheater or not to generate a neural impuse in order to pass incoming informaition on to other neuron
  6. What is the function of a dendrite?
    fibers prjecting out of cell body of a neuron whose fuction is to receive informeation from other neurons
  7. What is the function of the axom?
    long, singular fiber projecting out of the cell body of a neuron whose functiuon is to conduct the neural impulse from the cell body to the axon terminals triggering chemical communication with other neurons
  8. What is a neurotransmitter?
    naturally occuring chemical in the nervbous system that specializes in transmitting information between neurons
  9. What are the 6 major neurotransmitters?
    Serotonin, norepinephrine, gaba, and endorphines, dopamine, acytycholine
  10. What is the function of serotonin neurotransmitter?
    involved in levels of arousal and mood
  11. what is the function of norepinephrine neurotransmitter?
    involved in levels of arousal and mood
  12. what is the function of gaba?
    the main inhibitory neurotransmitter in the nrbvous system. It is involved in lowering arousal and axiety and regulating movement
  13. what is the function of endorphines?
    group of neurotransmitters that are inbolved in pain perception and relief
  14. what is the function of dopamine?
    neurotransmitter that impacts our arousal and mood states, tought processes, and physical movement
  15. what is the function of acytycholine?
    neurotransmitter involved in memory and muscle involvement
  16. What is the central nervous system?
    its made up of the brain and spinal cord
  17. what is the peripheral nervous system?
    part of nervous system that links the cns witht he bodys sensory receptors, muscles, and glands.
  18. what are the 3 types of neurons in the nervous system?
    Interneurons, sensory neurons, and motor neurons
  19. WHat is the function of a spinal cord?
    the conduit between the brain and the PNS for the incoming sensory data and outgoing movement comands to the muscles.
  20. What is the spinal reflex?
    simple automic action not requring involvement in the brain. Example the knee jerk.
  21. What is the function of the automic nervous system?
    part of the PNS that regulates the functioning of our internal environment as well as ow we experience and express emotion.
  22. What is the sympathetic nerbous system?
    is in controll when we are highly aroused as in emergency and need to prepare for defensive action
  23. what is the function of the parasympathetic nervoujs system?
    takes over when the aroused state ends to return the body to its normail resting state
  24. What is the James Lange theory?
    THeorey proposing emotion is determined from a cognitive appraisal of the physiological arousal and behavioral responses which occure first. physiological arousal nd backing away are responses to the stimulus of seeing a bear. You then interpret these automotic and behavioral responses as emotion fear.
  25. what is the common-barb-theory?
    proposing that emotion is determind from stimultaneously occuring physiological arousal behavioral response and cognitive appraisal. Argues that arousal patterns frodifferent emotions are 2 physiologically alike to be used to determin which emotion is being expressed.
  26. what is the Schachter and Singers two factor theory?
    an theory proposing tat an emothion is determind by cognitive appraisal of the physiological arousal and the entire environmental situation.
  27. What are the 2 sets of brain structures and what do they consist of?
    Central core (cerebellum, thalamus, and basal ganglia) and the limbivc system (hypothalamus, hippocampus, and amygdala).
  28. what is the function of the thalamus?
    serves as a relay station for incoming sensory information( visual autditory, taste, and touch)
  29. What is the function of pons?
    serve as the bridge between the cerebellum and the rest of the brain and is involved in sleep and dreaming
  30. what is the funciton of medulla?
    links the spinal cord, regulates many body functions such as heart beat, breathing, blood pressure, digestion, and swallowing.
  31. what is the function of the cerebellum?
    involved in corelating or our movement sense of balance and motor learning
  32. What the funtion of the basal gangtia?
    outer side of the thalamus and are concerned meainly witht he inition and execution of physicsal movements
  33. What is the function of hypothalamus?
    regulats basic drives such as eating drinking, and sex. Directs endorcine grandual system trhough ois controll of pitutary and automic nerbvous system to maintian bodys internal temp
  34. What is the funtion of the hippocampus?
    part of brain involved in formation of meories
  35. What is the funtion of amygdala?
    involved in emotion by inflouncing agression, anger, and frear and by providing the emothional element of meories and interpretation of emotional expression in others
  36. what is the function of cerebral cortex?
    the layer of interconnected cells covering the brain 2 hemispheres. the control and information processing. it is where perception, memory, language, decieion making, and all other higher level cognitive processing occur.
  37. What is the function of the frontal lobe? (cerebral cortex)
    are in front of cental fissure and abotge the lateral fissure. THe motor cortex is in this lobe
  38. what is the funtion of the pariental lobe? (cerebral cortex)
    area located behind the cental fissure and above the lateral fissure. The somotosensorey cortex is in this lobe.
  39. what is the function of temaral lobe?
    beneath the lateral fissure auditory cortex is in this lobe
  40. what is the funtion of the occipital lobe?
    lower back of each hemisphere. Visual cortex is in this lobe.
  41. what is the function of the motor cortex?
    allows us to move different parts of our body
  42. what is the function of somatosensory cortex?
    allows us to sense pressure, temp, and pain in defferent pars of our body as well as the position of our body parts
  43. what is the fucntion of the Broca's area?
    area in cerebral cortex responsible for fluent speech production
  44. What is the funtion of the Wernicke's area?
    is responsible for comprehension of speech and reacting
  45. 3 reasons why we need to sleep?
    1 serves as restorative function by allowing brain and body time to rest and recouperate, 2) process what we learn, 3) evolved as adaptative process
