The cerebral crus (crus cerebri) is the anterior portion of the cerebral peduncle which contains the motor tracts, travelling from the thalamus to the pons and spine. The plural of which is cerebral crura. It forms the majority of the basis pedunculi in the midbrain.

In some older texts this is called the cerebral peduncle but presently it is usually limited to just the anterior white matter portion of it.
