A finger knuckle joint, more precisely known as the metacarpophalangeal joint (MP joint), is the point where your hand bones (metacarpals) connect to your finger bones (phalanges). These joints are essential for hand function.
Understanding the Metacarpophalangeal (MP) Joint
The metacarpophalangeal joint is crucial for hand movements and dexterity.
Key Functions:
- Grip Strength: Enables a strong and stable grip.
- Pinch Activities: Facilitates precise movements.
- Finger Movement: Allows fingers to move in relation to the hand.
Anatomical Details:
| Term | Description |
|---|---|
| Metacarpal | The hand bone. |
| Phalanx (Phalanges) | The finger bone(s). A single finger bone is called a phalanx. |
| MP Joint | The junction where the metacarpal meets the phalanx, allowing finger movement relative to the hand. |
In summary, the finger knuckle joint (MP joint) is vital for everyday tasks, blending stability and movement to provide a versatile range of hand functions.
