1. What are the parts of the brain?
A: The parts of the brain are the brainstem with the thalamus bulb (thalamus, hypothalamus, medulla oblongata, Reticular Activating System, and brain stem), pons and connective tissue, cerebellum, cerebral penduncle, the "pyramid," superior colliculus, inferior colliculus, optic chiasm, hippocampus, pituitary gland, corpus callosum, and the cerebrum.
2. What are the functions of the different parts of the brain?
A: Brainstem with thalamus bulb: "thalamus"- meaning inner room; acts as relay station to incoming afferent messages.                          "hypothalamus"- regulates life support operations including endocrine system, hunger, thirst, motivation, sex, emotion, aggression
                                                        "medulla oblongata"- muscle coordination
                                                        " RAS (Reticular Activating System)- extends from upper medulla into lower thalamus area.               "brain stem"- houses spinal cord and extends all the way into the vertebrae and down to the base of the spine.
     Pons and connective tissue: control of breathing
     Cerebellum: coordination, balance, posture, and equilibrium
     Cerebral Penduncle: allows front of brain to communicate with the back of the brain
     The "Pyramid": an extension of the penduncle
     Superior Colliculus: help with visual perception
     Inferior Colliculus: help localize auditory information
     Optic Chiasm: allows the optic nerve to pass from one eye to the opposite hemisphere
     Hippocampus: associated with memory
     Pituitary Gland: produces hormones which controls other glands as well as various bodily functions.
     Corpus Callosum: integrate motor, sensory, and cognitive performances between the cerebral cortex on one side of the brain to the same region on the other side.
      Cerebrum: thinking skills
3. Why does each part have a different function?
A: Each part has a different function because they are specified by where they are placed, if one part does several functions than the brain would not be able to work the way it does and there might be more malfunctions.
