Dorsal and ventral: In animals with linear nervous systems, the term dorsal (from the Latin dorsum, meaning "back") is synonymous with superior and the term ventral (from the Latin venter, meaning "belly") is synonymous with inferior. In humans, however, the terminology differs on either side of the midbrain-diencephalic junction.
Superior (from Latin super 'above') describes what is above something [20] and inferior (from Latin inferus 'below') describes what is below it. [21] For example, in the anatomical position , the most superior part of the human body is the head and the most inferior is the feet.

The superior processes or prezygapophysis project upward from a lower vertebra, and their articular surfaces are directed more or less backward (oblique coronal plane). The inferior processes or postzygapophysis project downward from a higher vertebra, and their articular surfaces are directed more or less forward and outward.
Superior and inferior, which describe a position above (superior) or below (inferior) another part of the body. For example, the orbits are superior to the oris, and the pelvis is inferior to the abdomen. [1] Proximal and distal, which describe a position that is closer to (proximal) or farther from (distal) the trunk of the body. [1]
Extending laterally from it on either side is the superior nuchal line, and above it is the faintly marked highest nuchal line. A study of 16th-century Anatolian remains showed that the external occipital protuberance statistically tends to be less pronounced in female remains. [1]
In human anatomy, the anatomical planes are defined in reference to a body in the upright or standing orientation. A transverse plane (also known as axial or horizontal plane) is parallel to the ground; it separates the superior from the inferior, or the head from the feet.
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.
