Quiz Answer Key and Fun Facts
1. What is a horseshoe kidney?

Answer: A fully functional kidney that resulted from the fusion of the kidneys during development

The incidence of horseshoe kidney is between 1 in 400-800 live births, with the preponderance of the data suggesting it is closer to 1 in 400.
2. Which of the following is the longest?

Answer: Small intestine

Divided into three sections named the duodenum, jejunum, and ileum, the small intestine is 20 feet in length, compared to 10 inches for the esophagus, one foot for the stomach, and 5 feet for the large intestine.
3. The lingula is part of which organ?

Answer: Lung

The lingula is the tongue shaped portion of the left upper lobe of the lung which covers the heart. The lingula is the left lung's best "excuse" for a middle lobe, when in fact the right lung has three lobes and the left, only two.
4. The heart is composed of a special type of muscle fiber different from that found in other muscles of the body. Most muscle is skeletal, some is smooth muscle, and the heart is comprised of cardiac muscle which has which of the following characteristics?

Answer: all of these

Striated muscle is contained within the heart, which has the characteristic of autonomic contractility. Smooth muscle is contained in the intestines, and skeletal muscle moves the extremities, and provides movement and protection for most of the rest of the body.
5. A suntan develops as a result of which of the following?

Answer: Both

Oxidation of existing melanin by ultraviolet radiation causes the early tan and production of more melanin by the melanocytes in the skin results in delayed tanning.
6. The immune system has "memory cells" that remember exposure to antigens so the immune response can be quicker the second time if re-exposed to the antigen.

Answer: True

These are B lymphocytes, and are one of the main reasons vaccinations are so useful in preventing disease.
7. How is mucus removed from the bronchial tubes, other than by coughing?

Answer: Tiny projections called cilia on the cells lining the airway gradually move the secretions upward

The cilia are lost in smokers, and to protect itself, the delicate single layer of columnar cells which bear the cilia become stratified squamous cells, resembling the skin. The primary difference between the lining of the skin and the airway then is that skin cells are keratinized, to provide additional resistance to the elements.
8. Which of these statements is false?

Answer: Sperm are produced in males from birth until about age 70

Sperm begin to be produced at puberty between the ages of 12 and 15. Female infertility is identified in one half of cases, male infertility in a third, and the remainder of infertile cases have unknown causes.
9. The brain is composed mostly of what substance?

Answer: Water

Water comprises 77-78% of the brain, lipid or fat 10-12%, protein 8%, and carbohydrate approximately 1%.
10. Which of the following most closely resembles the arrangement of skeletal muscle fibers?

Answer: The cables of a suspension bridge

Parallel circular cables in intertwined groups is seen in both skeletal muscle fibers as well as the very durable, strong, and long lived suspension bridge cables.
