Palmer Spinal Exam 4 Practice

Which statement correctly describes the location of the anterior and posterior chambers of the eye?

Anterior chamber in front of the iris; posterior chamber behind the iris Posterior chamber in front of the iris; anterior behind the iris Anterior chamber behind the iris; posterior chamber in front of the iris Lateral chamber in front of the iris; medial behind the iris

Correct Answer:

Anterior chamber in front of the iris; posterior chamber behind the iris

Explanation:

The key idea is that the eye’s iris divides the inner space into two fluid-filled chambers. The anterior chamber lies between the cornea and the iris, while the posterior chamber lies behind the iris and in front of the lens, separated from the anterior chamber by the iris itself. Aqueous humor is produced in the posterior chamber, then flows through the pupil into the anterior chamber and drains out, helping maintain intraocular pressure. The other descriptions mix up the relative positions or refer to spaces that aren’t used as standard chambers.
