Study Notes
Phalanges Overview
- Phalanges are the bones that make up the fingers, classified as long bones.
- Each finger is composed of three phalanges: proximal, intermediate, and distal. The thumb (pollex) has only two phalanges (proximal and distal).
Thumb and Digits
- The thumb is known as the pollex, distinguishing it from other fingers.
- Each finger, except the thumb, includes an intermediate (middle) phalange.
Articulation and Joints
- Proximal phalanges articulate with metacarpals to form metacarpophalangeal joints, which allow for finger movement.
- Interphalangeal joints, located between the phalanges, are classified as hinge joints, facilitating flexion and extension.
Bone Structure
- Phalanges contribute to the overall structure and function of the hand, providing dexterity and strength.
- Being long bones, phalanges have a central shaft (diaphysis) and two ends (epiphyses).
