• Brain - weighs 3 pounds
• Brain - 60% fat, one of the fattest organ
• Brain - Gets 20% blood and oxygen
• Brain - Capable of surviving for 5-6 minutes
• Brain - 100 billion neurons
• Brain - Will lose consciousness after 8-10 seconds when blood supply is cut off
• 3 main parts of the Brain - Cerebrum, Cerebellum, Brain stem
• Cerebrum - Largest part of the brain

  - Composed of right and left hemispheres
• Functions of Cerebrum (TESHReLMV)

  • Interpreting Touch
  • Emotions
  • Speech
  • Hearing
  • Reasoning
  • Learning
  • Movement
  • Vision
• Cerebellum - Located under Cerebrum
• Functions of Cerebellum (MMPB)

  • coordinate Muscle Movements
  • maintain Posture
  • Balance
• Brainstem - connects Cerebellum and Cerebrum to Spinal cord
• Functions of Brainstem (BDSH)

  • controls Breathing
  • Digestion
  • Sneezing
  • Heart rate
• Lobes of the Brain

  • Frontal Lobe
  • Temporal Lobe
  • Parietal Lobe
  • Occipital Lobe
• Frontal Lobe

  • Personality, Behavior, Emotions

  • Pituitary Gland
  • Pineal Gland
  • Thalamus
  • Basal Ganglia
  • Limbic System
• Pituitary Gland

  • Master Gland - controls other glands
  • Secretes Hormones for - Sexual Development, Bone and Muscle Growth, Respond to Stress
• Pineal Gland

  • Located behind Third Ventricle
  • Secretes Melatonin: Regulates Body's internal clock, Circadian rhythm
• Thalamus

  • Relay station for information that comes and goes to the Cortex
  • Plays a role in Sensation, Attention, Alertness, Memory
• Basal Ganglia

  • Includes: Caudate, Putamen, Globus Pallidus
  • Works with the Cerebellum to coordinate fine motions
• Limbic System

  • Includes: Amygdala, Hippocampus, Cingulate Gyri, Hypothalamus
  • Center of Emotions, Learning, Memory
• Corpus Callosum - Bundle of fibers that connects Right and Left hemisphere
• Left hemisphere

  • Verbal
  • Analytical
  • Logical
• Right Hemisphere

  • Visual
  • Creative
