What is the function of the phalanges in the human body?

The phalanges are the bones that constitute the fingers and toes in humans. Each hand has 14 phalanges—three in each finger (proximal, middle, and distal) and two in the thumb (proximal and distal). Similarly, each foot has 14 phalanges—three in each toe (proximal, middle, and distal) and two in the big toe (proximal and distal). The primary function of the phalanges is to provide structure and support to the digits, allowing for a range of movements essential for grasping, holding, and manipulating objects. This role is crucial for tasks that require fine motor skills, making the phalanges an integral part of human dexterity.

While other options refer to different parts of the skeletal system, they do not accurately pertain to the specific function of the phalanges. The wrist and ankle support functions are performed by the carpals and tarsals, respectively, while the toes are indeed formed by the phalanges, but that option is too specific and does not fully encapsulate the overall role of the phalanges in the context of the whole digit structure.
