In the rostral direction, the midbrain noticeably splays laterally. The midbrain is typically sectioned axially at either the superior or inferior colliculi levels. Visualizing these cross-sections as an upside-down bear face helps remember its structures, with the peduncles forming ears, aqueducts mouth, and tectum chin.
Diagram showing the position of the colliculi. Superior shown in green and inferior in orange. View of the midbrain showing covering tectum and tegmental floor. The midbrain is further subdivided into three parts: tectum, tegmentum, and the ventral tegmental area. The tectum forms the ceiling.
The medial lemniscus, also known as Reil's band or Reil's ribbon (for German anatomist Johann Christian Reil), is a large ascending bundle of heavily myelinated axons that decussate in the brainstem, specifically in the medulla oblongata.

In humans, the tectospinal tract (or colliculospinal tract) is a decussating extrapyramidal tract that coordinates head/neck and eye movements. [1]It arises from the superior colliculus of the mesencephalic (midbrain) tectum, and projects to the cervical and upper thoracic spinal cord levels. [2]
The medial longitudinal fasciculus (MLF) is a prominent bundle of nerve fibres which pass within the ventral/anterior portion of periaqueductal gray of the mesencephalon (midbrain). [1] It contains the interstitial nucleus of Cajal , responsible for oculomotor control, head posture, and vertical eye movement.
The top section of the spine is the cervical section, which contains nerves that innervate muscles of the head, neck and thoracic cavity, as well as transmit sensory information to the CNS. The cervical spine section contains seven vertebrae, C-1 through C-7, and eight nerve pairs, C-1 through C-8.
The general structures of midbrain tegmentum include red nucleus and the periaqueductal grey matter. Nigrostriatal Pathway and Mesolimbic Pathway in the Dopaminergic System. Unlike the midbrain tectum (which is a sensory structure located posteriorly), the midbrain tegmentum, which locates anteriorly, is related to a number of motor functions.
