\begin{tabular}{l} 2. Which of the following is a type of bone that is present in both the upper \\ and lower limbs? \\ a. Phalanges \\ b. Carpals \\ c. Tarsals \\ d. Metacarpals \\ \hline\end{tabular}

The correct answer is d. Metacarpals. Metacarpals are the long bones in the hands that connect the wrist bones (carpals) to the finger bones (phalanges). Similarly, in the feet, you have metatarsals that connect the ankle bones (tarsals) to the toe bones (phalanges), making them a unique link between the upper and lower limbs in terms of structure. Interestingly, the metacarpals and metatarsals share a similar function in supporting the weight of the body and allowing for movement. They help your hands grasp and manipulate objects while providing stability in your feet during walking and running. So, whether you’re dancing at a party or sprinting down the street, those bones are working hard and keeping you balanced!
