  • Module 5.5: Plant and Animal Responses (The Brain)
    • Brain Protection
      • Skull
      • Cerebrospinal fluid (liquid cushion)
    • structure
      • cerebrum
      • Corpus Collosum
      • cerebellum
        • coordinates movement
      • Thalamus
      • Hypothalamus
        • thermoregulate, monitors blood
      • Pituitary gland
      • medulla oblongata
        • controls heartbeat
      • cerebra; hemispheres
        • ability to see, think, learn and feel emotion
    • Cerebrum
      • largest part
      • consists of five main lobes
        • frontal
        • parietal
        • occipital
        • temporal
        • cerebellum
      • divided into two hemispheres (cerebral)
        • joined by the corpus collosum
        • left hemisphere controls right and vice versa
      • cerebrum
        • thin outer layer (grey matter)
        • consists of neuron cell bodies that is highly folded
        • below id white matter
    • Cerebral Hemispheres
      • Frontal lobe
        • higher brain function (reasoning) + motor cortex
      • Parietal lobe
        • movement, sensation, recognition/memory
      • Occipital lobe
        • Visual cortex (processes eye info)
      • Temporal lobe
        • processes auditory information and is involved in memory
      • Cerebellum
        • under cerebrum
        • involuntary action
        • motor coordination - including balance
    • Pituitary Gland
      • Anterior
        • produces/releases hormones
      • posterior
        • stores/releases ADH
    • Medulla Oblongata
      • joins the spinal cord with the brain
      • three centres
        • cardiac centre
          • regulates heart rate
        • Respiratory centre
          • inspiratory/expiratory centre
        • Vasomotor centre
          • controls b.p.
