The tendon then splits: a attaches to the middle bone (middle phalanx), and two lateral bands continue forward to insert on the base of the distal bone (distal phalanx).
: These small intrinsic muscles are essential for balanced toe extension. They flex the MTP joints while extending both the proximal (PIP) and distal (DIP) interphalangeal joints. The tendon then splits: a attaches to the
: This intrinsic muscle on the top of the foot assists the EDL in extending toes 2, 3, and 4. : This intrinsic muscle on the top of
If the EDL acts entirely on its own without help from the intrinsic muscles, it tends to (the base of the toe) while the interphalangeal joints remain slightly bent. The intrinsic muscles like the lumbricals are needed to "fine-tune" the pull, allowing the toes to straighten completely without curling. The tendon then splits: a attaches to the
