BRAIN

• Brain - organ of the body in the head that controls functions, movements, sensation and thoughts
• 2 hemisphere of the brain:

  • Right Hemisphere
  • Left Hemisphere
• Right Hemisphere - dominant for spatial abilities, face recognition, visual imagery and music
• Left Hemisphere - responsible for controlling the right side of the body
• Left Hemisphere - performs tasks that have to do wihh logic, such as in science, and mathematics like calculations
• Right Hemisphere - responsible for controlling the left side of the body, and may be more dominant for creativity, imagination, rhythm and feelings
• The 4 lobes of the brain

  • Frontal lobe
  • Temporal lobe
  • Occipital lobe
  • Parietal lobe
• Frontal Lobe - known as the brocas area
• Frontal Lobe - named after Paul Broca
• Temporal Lobe - known as the wernicke's area
• Temporal Lobe - named after Carl Wernicke
• Occipital Lobe - derives from its position at the back of the head, from the Latin ob, 'behind', and caput, 'head'
• Temporal Lobe - named because of its proximity to the temples
• Neurotransmitters - chemicals who carry messages across the synapses or cell body of a receiving neuron
• Neurons - the basic functional units of the nervous system
• Synapses - refer to the points of contact between neurons where information is passed from one neuron to the next
• Serotonin - Affects mood, sleep, and appetite.
• Dopamine - a neurotransmitter that is involved in movement, learning, and attention
• Acetylcholine - a neurotransmitter that is involved in learning and memory
• Endorphins - natural painkillers that are released by the brain and spinal cord
• Norepinephrine - A neurotransmitter that is released by the adrenal medulla
• Norepinephrine - involved in arousal or mood
• GABA stands for?

  • Gamma Amino Butyric Acid
• Glutamate - involved the development of nervous system
• Gland - an organ in the human or animal body that secretes particular chemical substances
• Hormones - chemical messengers that travel through the bloodstream to target organs and cells
• Endocrine Gland - produces chemicals called hormones. These secretes directly into the bloodstream and influence the activities and functions of the muscles and organs and different glands
• Pituitary Gland - secrete of growths hormone and other important hormones
• Pineal Gland - produces melatonin, which is a hormone that regulates sleep and wake cycles
• Thyroid Gland - regulates growth and development by producing thyroxine
• Pancreas - produces hormones such as insulin which turn controls the level of sugar in the blood
• Adrenal Glands - control the stress reaction through the adrenal medulla's production of adrenaline
• Brain - wrinkled, pinkish-gray three pound organ that is primarily composed of fat and water
• Brain Stem - controls the heart rate, breathing, and swallowing.
• Cerebellum - control voluntary movement
• Cerebrum - the largest part of the brain, responsible for conscious thought and memory
• Cerebrum - accounts for about 85 percent of the brains weight
• Parietal Lobe - help understand why people see and feel
• Frontal Lobe - determine personality and emotion
• Occipital Lobe - vision functions
