Extensor tendons are fibrous tissues that connect muscles to bones in the fingers and toes. They play a crucial role in extending or straightening these digits, allowing for movements like grasping and pointing. These tendons run along the back of the hand and foot, attaching to the bones at various points. In the hand, extensor tendons are essential for fine motor skills and overall hand function. Injuries to these tendons can lead to difficulties in movement and may require medical intervention. Proper care and rehabilitation are important for recovery and restoring function to the affected area.
