Multiple Choice

How do the metatarsals contribute to the foot's ability to bear weight?

Their irregular shape helps them distribute the weight of the body.

The seven bones distribute the weight, so each bone only withstands a fraction of the total body weight.

The bones have additional collagen to help them resist force and twisting.

The bones help create arches that distribute the weight.

Verified step by step guidance

Begin by understanding the anatomy of the foot, which includes the metatarsals. These are the long bones located in the midfoot, connecting the tarsal bones to the phalanges (toes).

Recognize the function of the metatarsals in the foot's structure. They play a crucial role in forming the arches of the foot, which are essential for weight distribution.

Explore the concept of foot arches. The foot has three main arches: the medial longitudinal arch, the lateral longitudinal arch, and the transverse arch. These arches are formed by the arrangement of the bones, including the metatarsals.

Understand how the arches contribute to weight distribution. The arches act like a spring, absorbing shock and distributing the body's weight across the foot, reducing the stress on any single bone.

Consider the biomechanical advantage provided by the arches. The metatarsals, by helping to form these arches, enable the foot to bear weight efficiently, allowing for balance and movement while minimizing the risk of injury.
