  1. The nervous system consists of two parts. What are they?
    • - Central Nervous System (CNS)
    • - Peripheral Nervous System (PNS)
  2. What is the function of the CNS?
    • - consits of the brain and spinal cord
    • - receives, processes, interprets, and stores incoming information
    • - sends out messages to muscles, glands and organs
  3. What is the function of the PNS?
    • - consists of 43 pairs of nerves (31 spinal pairs and 12 brain pairs)
    • - handles input and output information from the CNS about what is happening inside and outside the body
  4. What are spinal nerves protected by?
    - spinal column
  5. The PNS consists of two parts. What are they?
    • - Autonomic Nervous System (ANS)
    • - Somatic Nervous System (SNS)
  6. What is the function of the ANS?
    - controls all the self regulating actions of internal organs and glands
  7. What is the function of the SNS?
    - controls voluntary movement of skeletal muscle
  8. The ANS consists of two parts. What are they?
    • - Sympathetic Nervous System
    • - Parasympathetic Nervous System
  9. What is the function of the Sympathetic Nervous System?
    - responsible for arousal "fight or flight"
  10. What is the function of the Parasympathetic Nervous System?
    - responsible for calming the body
  11. What are the three types of neurons?
    • - sensory neurons
    • - motor neurons
    • - interneurons
  12. What is the function of sensory neurons?
    - receives messages from outside nervous system and carries them to the CNS
  13. What is the function of motor neurons?
    - carries messages out from the CNS
  14. What is the function of interneurons?
    - receives messages from other neurons, is between the sensory and motor neurons
  15. Describe the Hindbrain.
    • - brain stem and the cerebellum
    • - coordinates the body
  16. Describe the Midbrain.
    • - limbic system 
    • - manages emotions and connects thought to body
  17. Describe the Forebrain.
    • - cortex
    • - integrates information
  18. Describe the Cerebral Cortex.
    • - outer covering of the two hemispheres
    • - perception, emotion, movement and thought
  19. Describe the Occipital Lobe.
    • - visual information
    • - visual cortex
  20. Describe the Parietal Lobe.
    • - information about touch
    • - sensory cortex
  21. Describe the Temporal Lobe.
    • - hearing language
    • - auditory cortex
  22. Describe the Frontal Lobe.
    • - planning, judgment, memory, reasoning, abstract thinking and movement
    • - motor cortex
  23. What is the Broca's Area and where is it located?
    • - is responsible for speech production
    • - is located in the Frontal Lobe
  24. What is the Wernicke's Area and where is it located?
    • - is responsible for language comprehension
    • - is located in the Temporal Lobe
  25. What is the Motor Cortex and where is it located?
    • - is responsible for output from the brain
    • - is located in the Frontal Lobe
  26. What is the Sensory Cortex and where is it located?
    • - is responsible for input to the brain 
    • - is located in the Parietal Lobe
  27. What are the Parietal Lobe Association areas?
    • - managing sensory input
    • - spatial and mathematical reasoning
    • - monitoring sensation of movement
  28. What are the Temporal Lobe Association areas?
    • - recognizing specific faces
    • - sound input, understanding spoken words
  29. Describe the Medulla.
    • - first structure after the spinal cord
    • - responsible for automatic functions like heart rate and breathing
  30. What is the function of the Pons?
    • - neurons responsible for sleep and dreaming
    • - motor neurons responsible for controlling the muscles and glands in the face and neck
  31. Where is the function of the RAS and where is it located?
    • - arouses the cortex and screens incoming information
    • - extends from brain stem
  32. What is the function of the Thalamus?
    • - sensory input (except smell) is routed through the Thalamus on the way to the cortex
    • - sends information from the cortex to the medulla and cerebellum
  33. What is the function of the Cerebellum?
    - coordinates voluntary movements, enables non verbal learning and memory
  34. What is the function of the Basal Ganglia?
    • - receives information from the cerebral cortex
    • - sends output to the motor cortex
    • - voluntary control of posture and movement
  35. What three parts make up the Limbic System?
    • - Amygdala
    • - Hippocampus
    • - Hypothalamus
  36. What is the function of the Amygdala?
    - processes emotions especially fear and aggresion
  37. What are the functions of the Hippocampus?
    • - processes conscious, episodic memories
    • - works with the Amygdala to form emotionally charged memories
  38. What are the functions of the Hypothalamus?
    • - regulates body temperature
    • - houses reward center
    • - part of it uses light cues to regulate sleep cycle
    • - controls maintenance functions like eating and drinking
  39. What does the Corpus Callosum do?
    - hold the two hemispheres together
  40. Define experience-expectant plasticity in infants.
    - requires basic common experiences to develop normally such as being loved and nurtured
  41. What is experience-dependent plasticity in infants?
    - happens to some infants but not all such as hearing the same language over and over
  42. What are the functions of the left hemisphere?
    • - thoughts and logic
    • - details "tree"
    • - language, words and definitions
    • - linear and literal
    • - calculations
    • - pieces and details
  43. What are the functions of the right hemisphere?
    • - feelings and intuition
    • - big picture "forest"
    • - language, tone and context
    • - inferences and associations
    • - perception
    • - wholes, including ones self
