Anatomy and Physiology

    Organisation of the Body
    To which body region does “popliteal” refer?
    Here the popliteal artery and popliteus tendon may be located. Choice A refers to orbital; B refers to antecubital; D refers to inguinal.
    Nervous System
    Which word correctly completes the statement: “All motor neurons are…”?
    Motor neurones (that innervate muscles) are multipolar.
    Nervous System
    Corticospinal pathways cross over from one side of the brain to the other side. Where does this crossover occur?
    In the medulla oblongata at the “decussation of pyramids”.
    Reproductive System
    Below is a list of structures and (in brackets) a hormone that they might produce. Which list is correct?
    The anterior pituitary produces and releases FSH and LH.
    Gastrointestinal System
    What is the term applied to the production of glucose from noncarbohydrate molecules?
    Gluco refers to glucose; neo = new; and genesis = producing (glycogenolysis is the production of glucose from glycogen – by lysis.)
    Respiratory System
    The term “cellular respiration” is applied to:
    Cellular respiration is applied to the use of oxygen in mitochondria to metabolise glucose into ATP and carbon dioxide.
    Cardiovascular System
    Which of the following would cause blood pressure to DECREASE?
    Parasympathetic activity decreases heart rate and decreases force of myocardial contraction; hence CO and BP would decrease.
    Chemistry for Physiology
    The formula for glucose is C6H12O6. How many atoms of each type of element are there in a molecule of glucose?
    The number of atoms, written as a subscript, immediately follows the symbol for the element and C, H, O are the symbols for carbon, hydrogen and oxygen, respectively.
    Chemistry for Physiology
    Which one of the following best defines an acid?
    A “hydrogen ion” H+ is a bare proton which, if it freely exists, would attach to a water molecule to form the hydronium ion (H3O+). So choice D is a better answer than Choice B.
    The Physics of Waves: Light Waves, Sound Waves and Ultrasound
    Ultrasound radiation may be characterised as which one of the following?
    Ultrasound, and audible sound, is a longitudinal wave. It is neither ionising nor electromagnetic.
