Quiz Answer Key and Fun Facts

1. Ants have a hard outer shell on their bodies which acts as an exoskeleton and enables them to do what that seems remarkable to humans?

Answer: lift 20 times their weight

Entomologists (people that study insects) say that an ant can lift things that weigh 20 times what they do. If a human could do that, a 180 pound (80 kilogram) man could lift over 3,600 pounds (about 1,600 kilograms).

2. In a human, what area of the body is sphenoid bone closest to?

Answer: the side of the head

The sphenoid is a butterfly-shaped bone spanning the cranium (skull) between the eye sockets and the ear canal extending behind the eye sockets and straddling the nasal orifice. Its name derives from the Latin sphenoides meaning wedge-shaped.

3. Which of these vertebrates has no true bones?

Answer: sharks

Sharks support their bodies with cartilage and connective tissue. Cartilage is more flexible and about half the density of bones. Sharks also do not have rib cages. The other animals listed are true vertebrates and have an internal skeleton.

Answer: the tibia and fibula

The tibia is the main, weight-bearing bone and the fibula is the smaller bone on the outer part of the leg. The name tibia derives from the Latin "tibia" meaning "pipe" or "flute". Fibula is also from Latin and means "clasp" or "brooch," which is related to meaning "to fasten or fix".

5. Statistically, which is the most common SINGLE bone broken in the human body in people under age 75?

Answer: collar bone

The most commonly single broken bone in the body is the clavicle, or collar bone, which is usually broken in falls and sporting activities. Although the wrist is the most commonly injured area, it consists of multiple bone structures. After age 75, hip fractures are the most common.

6. The center of mammalian long bones contains soft pulp called marrow. Which is NOT a function of this tissue?

Answer: enzyme production

In an adult human, bone marrow roughly constitutes 4% of body weight. An amazing biological substance, bone marrow assists the spleen in blood cell formation. The bone marrow in a human body produces millions of red blood cells in a day.

7. Humans and giraffes have the same number of bones in their necks.

Answer: true

All mammals have seven bones in their neck. The giraffe's are just longer.

8. On average, how long does it take a fractured bone to "knit" to the point it needs no further support?

Answer: six weeks

You'd probably think it was much longer if you ever had an arm or leg in a cast. The crucial parts of mending a broken bone are re-aligning the broken ends and immobilizing the affected area.

9. The human body contains just over 200 bones. However, over half of them are found in which two areas?

Answer: hands and feet

There are a total of 106 bones in the hands and feet - 26 bones in each foot and 27 in each hand. This makes them very flexible - a good thing for manual dexterity and a smooth walking gait.

Answer: heel

The calcaneus is the scientific term for the heel bone. It is the largest bone in the foot and a major weight bearing bone.
