  1. 1At the pubic symphysis, the two hip bones are united by a pad of fibrocartilage that permits only a small amount of movement. Under the functional classification of joints used for the appendicular skeleton, this articulation is an example of which class?

    1. A. Amphiarthrosis
    2. B. Synarthrosis
    3. C. Diarthrosis
    4. D. Syndesmosis

    Answer: A

    Explanation: The functional classification of joints turns on how much movement the articulation permits, and the fibrocartilage pad at the pubic symphysis is the standard example of the slightly movable class: "Slightly movable joints are called amphiarthroses." and "The symphysis pubis is a slightly movable joint in which there is a fibrocartilage pad between the two bones." A synarthrosis is immovable, because in those joints the bones are separated only by a thin layer of fibrous connective tissue, as in the skull sutures. A diarthrosis is freely movable and has a joint cavity lined by a synovial membrane. A syndesmosis is a fibrous union, not a fibrocartilaginous one, and does not describe the pubic symphysis.

  2. 2Counting the paired and unpaired bones separately, how many cranial bones are listed in the axial skeleton?

    1. A. 8
    2. B. 14
    3. C. 6
    4. D. 28

    Answer: A

    Explanation: The cranial group is enumerated bone by bone with the number of each: "Cranial Bones Parietal (2) Temporal (2) Frontal (1) Occipital (1) Ethmoid (1) Sphenoid (1)", which totals eight. The figure of 14 is the count of the facial group, which begins "Facial Bones Maxilla (2) Zygomatic (2) Mandible (1)" and continues to the vomer. Six is the count of the auditory ossicles, listed as "Auditory Ossicles Malleus (2) Incus (2) Stapes (2)". Twenty-eight is the total for the whole skull, which is entered as "Skull (28)" and includes the cranial bones, the facial bones, the ossicles, and the hyoid.

  3. 3Sodium channels are described as central to a cell's ability to generate and transmit electrical signals. What do these channels actually do?

    1. A. They transport positively charged sodium ions into cells
    2. B. They transport positively charged sodium ions out of cells
    3. C. They exchange sodium ions for potassium ions in a fixed ratio
    4. D. They bind sodium ions to the membrane without moving them across it

    Answer: A

    Explanation: The function of the channel family is stated in terms of the direction of ion movement: "The SCN4A gene belongs to a family of genes that provide instructions for making sodium channels. These channels, which transport positively charged sodium atoms (sodium ions) into cells, play a key role in a cell's ability to generate and transmit electrical signals." In skeletal muscle that inward movement is what starts contraction, because "Muscle contractions are triggered by the flow of ions, including sodium, into skeletal muscle cells." Moving sodium outward, exchanging it for potassium in fixed stoichiometry, or merely binding it would not produce that inward current.

  4. 4In glycogen storage disease type V, muscle cells cannot break down glycogen. What symptom pattern does that produce?

    1. A. Fatigue, muscle pain, and cramps during the first few minutes of exercise
    2. B. Fatigue, muscle pain, and cramps only after several hours of exercise
    3. C. Enlargement of the liver and low blood sugar after a period of fasting
    4. D. Progressive weakness of the facial and breathing muscles at rest

    Answer: A

    Explanation: The defect is in mobilizing stored carbohydrate inside the muscle cell: "Glycogen storage disease type V (also known as GSDV or McArdle disease) is an inherited disorder caused by an inability to break down a complex sugar called glycogen in muscle cells. A lack of glycogen breakdown interferes with the function of muscle cells." The timing follows from that, since muscle relies on its own glycogen at the start of activity: "People with GSDV typically experience fatigue, muscle pain, and cramps during the first few minutes of exercise". A liver-centred picture belongs to a different type of the same disease family, in which glycogen accumulates "especially the liver, kidneys, and small intestines". Weakness of facial and breathing muscles at rest describes a neuromuscular junction disorder rather than a glycogen defect.

    Reference: Glycogen storage disease type V: MedlinePlus Genetics — Glycogen storage disease type V, 'Description'

  5. 5A mutated gene produces a defective protein that keeps a growth-factor receptor switched on even though no growth factor is present. What is this type of altered gene called, and what kind of mutation is it?

    1. A. An oncogene, produced by a dominant mutation
    2. B. A tumor suppressor gene, produced by a dominant mutation
    3. C. An oncogene, produced by a recessive mutation
    4. D. A tumor suppressor gene, produced by a recessive mutation

    Answer: A

    Explanation: Gene changes in cancer fall into two classes, and the stem describes the first: "One type, dominant mutation, is caused by an abnormality in one gene in a pair." The example given for it is a receptor stuck in the active state, so that "The result is that the cell receives a constant message to divide." A gain-of-function gene of that kind is what is termed an oncogene. The other class needs both copies to be lost: "The second general type of mutation, recessive mutation, is characterized by both genes in the pair being damaged." That is the class the suppressors belong to, since a gene such as p53 "is called an anti-oncogene or tumor suppressor gene".

  6. 6How does a precaution differ from a contraindication in the immunization framework?

    1. A. A precaution is a condition that might increase the risk of a serious adverse reaction, cause diagnostic confusion, or compromise the immune response
    2. B. A precaution is a condition that always prohibits administration because of the risk of a serious adverse reaction
    3. C. A precaution is a condition that requires a reduced dose rather than a full dose of the vaccine
    4. D. A precaution is a condition that applies only to people with a documented severe allergic reaction

    Answer: A

    Explanation: The weaker of the two categories is defined by three possible problems rather than by absolute prohibition: "A precaution is a condition in a recipient that might increase the risk for a serious adverse reaction, might cause diagnostic confusion, or might compromise the ability of the vaccine to produce immunity." A documented severe allergic reaction falls in the stronger category instead, since "Severe allergic reaction (e.g., anaphylaxis) after a previous dose or to a vaccine component" is listed as a contraindication. No dose reduction rule is described.

  7. 7A patient sustains a fracture of one of the eight cube-shaped bones of the wrist, which have vertical and horizontal dimensions that are approximately equal. Under the four principal shape categories used to classify bones, the fractured bone belongs to which category?

    1. A. Short bone
    2. B. Long bone
    3. C. Flat bone
    4. D. Irregular bone

    Answer: A

    Explanation: Bone shape classification is defined by proportions rather than by absolute size: "Short bones are roughly cube shaped with vertical and horizontal dimensions approximately equal." and the wrist is given as the type example, since "Short bones include the bones of the wrist and ankle." Long bones are excluded because they "consist of a long shaft with two bulky ends or extremities", which the carpals do not have. Flat bones are "thin, flattened, and usually curved", a description that fits most cranial bones. Irregular bones are the residual category for bones that fit none of the other three, such as the vertebrae.

  8. 8The pituitary gland rests in a bony depression at the base of the skull. Which bone contains that depression?

    1. A. The sphenoid bone
    2. B. The ethmoid bone
    3. C. The occipital bone
    4. D. The temporal bone

    Answer: A

    Explanation: The gland is almost enclosed by bone, and the bone is named along with the depression: "It is nearly surrounded by bone as it rests in the sella turcica, a depression in the sphenoid bone." The ethmoid, occipital, and temporal bones are all real cranial bones from the same list, but none of them carries the sella turcica. The occipital bone is the one pierced by the foramen magnum, where "The brain is continuous with the spinal cord at the foramen magnum", and the temporal bones house the auditory ossicles. The NCI anatomy manual places the gland the same way: it is "Located at the base of the brain behind the eyes in the sella turcica of the sphenoid bone".

  9. 9How does one neuron pass information to the next, and across what structure?

    1. A. By sending chemicals called neurotransmitters across a tiny space called a synapse
    2. B. By sending chemicals called neurotransmitters through a continuous cytoplasmic bridge
    3. C. By conducting an electrical current directly through the myelin sheath into the next cell
    4. D. By releasing hormones into the bloodstream that reach the next neuron

    Answer: A

    Explanation: Transmission between cells is chemical and crosses a gap: "Neurons communicate with each other by sending chemicals, called neurotransmitters, across a tiny space called a synapse, between the axons and dendrites of nearby neurons." The ends of the sending fiber are specialized for that release, since axon branches "terminate in many short branches or telodendria. The distal ends of the telodendria are slightly enlarged to form synaptic bulbs." No cytoplasmic bridge is involved, and the myelin sheath is insulation on the axon rather than a conduit into the next cell. Hormones do travel in the blood, but that is the endocrine route rather than neuron-to-neuron signalling.

  10. 10In glycogen storage disease type I, which substance accumulates, and in which organs does that accumulation impair function?

    1. A. Glycogen; especially the liver, kidneys, and small intestines
    2. B. Glucose; especially the liver, kidneys, and small intestines
    3. C. Glycogen; especially the skeletal muscles and the heart
    4. D. Galactose; especially the liver, kidneys, and small intestines

    Answer: A

    Explanation: The stored polymer is the one that builds up, and the affected organs are named: "Glycogen storage disease type I (also known as GSDI or von Gierke disease) is an inherited disorder caused by the buildup of a complex sugar called glycogen in the body's cells. The accumulation of glycogen in certain organs and tissues, especially the liver, kidneys, and small intestines, impairs their ability to function normally." It is the polymer rather than free glucose that accumulates. Muscle is the site affected in a different type of the same family, in which the inability to break down glycogen occurs "in muscle cells". Galactose accumulates in a separate disorder of sugar handling.
