Summary Introduction
To review:
The functional relationship between the oculomotor, trochlear, and abducens nerves.
Introduction:
The cranial nerves III, IV, as well as VI, that is, the oculomotor nerve, the trochlear nerve, and the abducens, respectively, are the motor nerves. These nerves contain the axons of the motor nerve cells when they leave the brainstem.
