[10] The brachium of superior colliculus (or superior brachium) is a branch that extends laterally from the superior colliculus, and, passing to the thalamus between the pulvinar and the medial geniculate nuclei, is partly continued into an eminence called the lateral geniculate nucleus, and partly into the optic tract.

The tegmentum is the location of several cranial nerve nuclei. The nuclei of CN III and IV are located in the tegmentum portion of the midbrain. The nuclei of CN V to VIII are located in the tegmentum at the level of the pons. The nuclei of CN IX, X, and XII are located in that of the medulla. [citation needed]
The red nucleus or nucleus ruber is a structure in the rostral midbrain involved in motor coordination. [1] The red nucleus is pale pink, which is believed to be due to the presence of iron in at least two different forms: hemoglobin and ferritin. [2]

It arises from the superior colliculus of the mesencephalic (midbrain) tectum, and projects to the cervical and upper thoracic spinal cord levels. [2] It mediates reflex turning of the head and upper trunk in the direction of startling sensory stimuli (visual, auditory, or skin). [2] It arises from the deep layers of the superior colliculus.
