• Parts of the Brain
  • Forebrain
    • Cerebrum
      • The large rounded structure of the brain occupying most of the cranial cavity, divided into two cerebral hemispheres that are joined at the bottom by the corpus callosum. It controls and integrates motor, sensory, and higher mental functions, such as thou
    • Thalamus
      • A large ovoid mass of gray matter situated in the posterior part of the forebrain that relays sensory impulses to the cerebral cortex
    • Hypothalamus
      • The part of the brain that lies below the thalamus, forming the major portion of the ventral region of the diencephalon and functioning to regulate bodily temperature, certain metabolic processes, and other autonomic activities
  • Midbrain
    • Tectum
      • A rooflike structure in the dorsal part of the midbrain
    • Tegmentum
      • A part of the midbrain consisting of white fibers running lengthwise through gray matter
  • Hindbrain
    • Cerebellum
      • The trilobed structure of the brain, lying posterior to the pons and medulla oblongata and inferior to the occipital lobes of the cerebral hemispheres, that is responsible for the regulation and coordination of complex voluntary muscular movement as well
    • Pons Varolli
      • A band of nerve fibers on the ventral surface of the brain stem that links the medulla oblongata and the cerebellum with upper portions of the brain
    • Medulla
      • The inner core of the brain
• Parts of the Heart
  • Aorta
    • The main trunk of the systemic arteries, carrying blood from the left side of the heart to the arteries of all limbs and organs except the lungs
  • Aortic valve
    • A heart valve comprising three flaps which guards the passage from the left ventricle to the aorta and prevents the backward flow of blood
  • Bicuspid Valve
    • The heart valve preventing back flow of blood from the left ventricle to the left atrium
  • Cardiac septem
    • The thin partition or membrane that divides the cavities the heart
  • Left atrium
    • The left upper chamber of the heart that receives blood from the pulmonary veins
  • Left ventricle
    • The chamber on the left side of the heart that receives the arterial blood from the left atrium and contracts to force it into the aorta
  • Pulmonary artery
    • An artery that carries venous blood from the right ventricle of the heart to the lungs
  • Pulmonary valve
    • A valve consisting of three semilunar cusps situated between the right ventricle and the pulmonary trunk
  • Pulmonary vein
    • A vein that carries oxygenated blood from the lungs to the left atrium of the heart
  • Right atrium
    • The right upper chamber of the heart that receives blood from the venae cavae and coronary sinus
  • Right ventricle
    • The chamber on the right side of the heart that receives venous blood from the right atrium and forces it into the pulmonary artery
  • Tricuspid valve
    • The three-segmented valve of the heart that keeps blood in the right ventricle from flowing back into the right atrium.
