the brain

    Cards (229)

    • What is the brain made up of?
      Billions of interconnected nerve cells
    • What functions does the brain perform?
      Holds thoughts, memories, and complex behaviors
    • What does the brain control in terms of behavior?
      Choosing clothes, running, and reading
    • What are the main regions of the brain and their functions?
      • Cerebral cortex: consciousness, intelligence, memory, language, vision, hearing
      • Cerebellum: balance and muscle coordination
      • Hypothalamus: regulates body temperature and signals pituitary gland
      • Brain stem: connects brain to spinal cord, controls unconscious activities
    • What is the cerebral cortex also known as?
      Cerebrum
    • How do the hemispheres of the brain function?
      Left controls right side muscles, right controls left
    • What is the role of the cerebellum?
      Controls balance and muscle coordination
    • What does the hypothalamus regulate?
      Body temperature and signals to the pituitary gland
    • What connects the brain to the spinal cord?
      Brain stem
    • What does the medulla control?
      Unconscious activities like breathing and heart rate
    • What methods do scientists use to study the brain?
      • Study of brain damage
      • Electrical stimulation of brain regions
      • Brain scanning techniques (CT, PET, MRI)
    • How can studying brain damage help scientists?
      It indicates which regions control specific functions
    • What happens when a specific brain region is damaged?
      It can lead to loss of specific functions
    • What does electrical stimulation of the brain do?
      Can cause muscle contractions or visual changes
    • What is the purpose of CT scans?
      To see which areas of the brain are damaged
    • How do PET and MRI scans differ from CT scans?
      They measure underlying brain activity
    • What might happen in an MRI machine when shown sad images?
      Specific brain parts appear brighter
    • Why is treating the brain difficult?
      Wide range of issues and fragile structure
    • What are some issues that can affect the brain?
      Tumors, infections, trauma, mental health problems
    • Why is surgery on the brain challenging?
      It's encased in the skull and fragile
    • Why are drugs and chemicals difficult to use for brain treatment?
      We don't fully understand brain processes
    • What are the challenges in treating brain conditions?
      • Wide range of potential issues
      • Fragile structure encased in skull
      • Complexity and lack of understanding
    • What does the brain control?
      Complex behaviour
    • What is the brain part of?
      Central nervous system (CNS)
    • What can complex behaviour include?
      Emotions, memory, and conscious responses
    • What are reflexes?
      Unconscious responses not involving the brain
    • How is the brain described in terms of complexity?
      It works with incredible complexity
    • How many interconnected neurones does the brain have?
      Billions
    • What does the cerebral cortex control?
      Emotions, thoughts, personality, intelligence
    • How many hemispheres does the cerebral cortex have?
      Two
    • What does each hemisphere of the cerebral cortex control?
      One side of the body
    • How many areas can the cerebral cortex be split into?
      Over 50 different areas
    • What is the function of the cerebellum?
      Controls movement and balance
    • What happens without the cerebellum?
      Movements would be erratic and uncoordinated
    • What does the medulla oblongata control?
      Unconscious control like heart rate
    • What does the medulla produce during exercise?
      Adrenaline
    • What is the role of the hypothalamus?
      Involved in homeostasis
    • What does the hypothalamus help maintain?
      Body temperature
    • What does the pituitary gland produce?
      Important hormones
    • Which hormones are produced by the pituitary gland?
      FSH and LH
