Lateral view of a sheep brain with the internal capsule transected. The
rostral colliculus (rc) and the
caudal colliculus (cc) form the
tectum (roof) of the midbrain. Axons travel from the caudal colliculus to the medial geniculate (mg) through the brachium of the caudal colliculus (asterisk). The
crus cerebri (cr) is evident on the ventral surface of the midbrain
.
