    Study Notes

    Hind Brain

    • Located at the base and back of the brain
    • Contains the medulla oblongata and cerebellum
    • Medulla oblongata
      • Found at the bottom of the brainstem
      • Responsible for relaying information between the spinal cord and the brain
      • Controls vital functions like breathing and heart rate
    • Cerebellum
      • A convoluted structure located at the back of the brain
      • Plays a crucial role in maintaining balance and judging distances
      • Situated beneath the cerebrum

    Mid Brain

    • Contains the reticular formation
    • Reticular formation
      • A network of nuclei distributed throughout the brainstem
      • Involved in regulating the sleep-wake cycle
      • Helps maintain wakefulness and alertness

    Fore Brain

    • Includes the hypothalamus, thalamus, and cerebrum
    • Hypothalamus
      • Located above the thalamus
      • Influences basic drives such as eating, body temperature, and sexual behavior
      • Controls the release of hormones from the pituitary gland
    • Thalamus
      • A double-lobed structure positioned above the brainstem
      • Receives sensory information (except smell)
      • Transmits this information to the cerebral cortex
    • Cerebrum
      • Divided into two cerebral hemispheres
      • Responsible for higher-order cognitive processes such as language, memory, and reasoning
