This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on.
Posterior chamber of eyeball. Anterior part of the human eye, with label of posterior chamber at right. The posterior chamber is a narrow space behind the peripheral part of the iris, and in front of the suspensory ligament of the lens and the ciliary processes. The posterior chamber consists of small space directly posterior to the iris but ...
Posterior segment of eyeball. The posterior segment or posterior cavity[1] is the back two-thirds of the eye that includes the anterior hyaloid membrane and all of the optical structures behind it: the vitreous humor, retina, choroid, and optic nerve. [2] The portion of the posterior segment visible during ophthalmoscopy (or fundoscopy) is ...

List of anatomical lines. Axillary lines. Vertical lines: Midline, lateral sternal line, parasternal line and midclavicular line. Horizontal lines: Level of the sternal angle, and zipho-sternal line. Anatomical "lines", or "reference lines," are theoretical lines drawn through anatomical structures and are used to describe anatomical location.
