Question 1

How do you say Metatarsals?

Accepted Answer

Metatarsals is pronounced met-uh-TAR-sulz. Break it into four parts: MET, then uh, then TAR, then sulz. The stress falls on the third syllable, TAR, so you say it met-uh-TAR-sulz. Say it a few times fast and it starts to feel natural pretty quickly.

Question 2

What does Metatarsals mean?

Accepted Answer

Metatarsals means the bones beyond the tarsals. The word comes from Greek, where meta means beyond or after, and tarsos referred to the flat of the foot. They are the five long bones that make up the middle of the foot, sitting between the ankle bones and the toe bones. Every time you look at the top of your foot, those long ridges you can feel are your metatarsals.

Question 3

Where are the metatarsals in the foot?

Accepted Answer

Metatarsals sit in the middle section of the foot, often called the midfoot. They connect the tarsal bones of the ankle above them to the phalanges, which are the toe bones, below them. There are five of them, one leading to each toe, and they form most of the length and arch of the foot. You can feel them as the long bony ridges on the top of your foot.

Question 4

Did T. rex have metatarsals?

Accepted Answer

Yes, T. rex had three main metatarsals it actually walked on, numbered two, three, and four. The first and fifth were reduced and not weight-bearing. The third metatarsal was pinched at the top in a special shock-absorbing arrangement called the arctometatarsalian condition. This design helped T. rex move efficiently and may have reduced the risk of stress fractures from its massive weight.

Question 5

How many metatarsals do humans have?

Accepted Answer

Humans have five metatarsals in each foot, giving us ten metatarsals total. They are simply numbered one through five, starting from the big toe side and going out to the little toe. Interestingly, the second metatarsal is the longest of the five, not the first, which is why many people notice their second toe appears to extend further than their big toe.

Question 6

What is the difference between metatarsals and tarsals?

Accepted Answer

Tarsals are the cluster of seven bones that make up the ankle and the back part of the foot, including the heel bone and the bone on top of the foot just in front of the ankle. Metatarsals are the five long bones that come next, extending from those ankle bones toward the toes. Think of it as a sequence: tarsals first, then metatarsals, then phalanges at the very tips.

Question 7

Do birds have metatarsals?

Accepted Answer

Yes, birds have metatarsals, and they are actually fused together into a single combined bone called the tarsometatarsus. This fusion happened over millions of years of dinosaur evolution and makes the bird foot extremely strong and lightweight. Because birds are the living descendants of theropod dinosaurs, their fused metatarsus is a direct evolutionary echo of the elongated theropod foot bones seen in fossils like Velociraptor.

Question 8

What dinosaur had the longest metatarsals?

Accepted Answer

Some of the largest sauropods, including Brachiosaurus and Argentinosaurus, had individual metatarsals that could measure over 50 centimeters long. However, for their body size, theropods like Gallimimus and Struthiomimus had proportionally the longest and most slender metatarsals of any dinosaurs, giving them a long springy stride similar to a modern ostrich. Those long proportions are directly linked to high running speed.

Question 9

Can you break a metatarsal?

Accepted Answer

Yes, metatarsal fractures are actually one of the most common foot injuries in both humans and, based on fossil evidence, in dinosaurs too. In humans, metatarsal stress fractures are frequent in runners and dancers because of the repetitive impact those bones absorb. Fossilized dinosaur metatarsals have been found with healed fracture lines, telling us that some dinosaurs survived these injuries and lived on for months or years afterward.

Question 10

What is the arctometatarsalian condition in dinosaurs?

Accepted Answer

The arctometatarsalian condition is a special foot bone arrangement found in many theropod dinosaurs where the third metatarsal is pinched and compressed at its upper end, nearly sandwiched between the second and fourth metatarsals. The name comes from Greek arktos meaning compressed or close-fitted. Scientists believe this design acted as a natural shock absorber and spring, making the foot more efficient for high-speed running. It evolved independently several times across different theropod lineages, which suggests it was a very successful adaptation.

Question 11

How do scientists use metatarsals to figure out how fast dinosaurs ran?

Accepted Answer

Paleontologists use a measurement called the metatarsal-to-femur ratio, comparing the length of the metatarsal to the length of the upper leg bone. Animals with longer metatarsals relative to their femur tend to be faster runners, a pattern seen across modern animals from ostriches to cheetahs. Researchers like James Farlow have applied this method to fossil bones to estimate running speeds for dozens of extinct dinosaurs. When combined with trackway data showing actual stride lengths, these calculations become even more accurate.

Question 12

Are metatarsals the same as metacarpals?

Accepted Answer

They are similar but not the same. Metatarsals are the long bones in the foot, while metacarpals are the long bones in the hand. Both names follow the same Greek naming logic, with meta meaning beyond, tarsal referring to the foot, and carpal referring to the wrist. In dinosaurs, the forelimb metacarpals were often very different in shape from the hindlimb metatarsals, reflecting the totally different jobs those limbs performed.

Question 13

Why do some people say metatarsal when a soccer player gets injured?

Accepted Answer

Metatarsal fractures became widely known in soccer circles after David Beckham broke his second metatarsal in April 2002, just weeks before the FIFA World Cup. Several other high-profile soccer players suffered the same injury in subsequent years, making it a frequently heard word in sports news. Metatarsals in the foot take enormous stress during kicking and pivoting, making them vulnerable in high-impact sports. The injury is serious because these bones are critical for pushing off the ground, walking, and running.
