Final answer:

Ia and Ib fibers are the type of nerve fibers that sense proprioception in the medial dorsal horn of the spinal cord.

Step-by-step explanation:

The type of nerve fibers that sense proprioception in the medial dorsal horn of the spinal cord are Ia and Ib fibers. These fibers are fast, heavily myelinated fibers that transmit sensory information about muscle length and tension. They are responsible for providing the brain with information about the position and movement of the body.
