Summary Introduction

To review:

Label the given diagram with proper anatomical terms.

Introduction:

The receptors for vision are contained in the eyes. It enables an individual to detect light and thus, create a detailed visual image.

Explanation of Solution

The labeled diagram is given below:

The structures shown in the given diagram are described below:

Posterior cavity: It is also known as vitreous chamber that consists of the gelatinous vitreous body. The vitreous body stabilizes the eye shape.

Posterior chamber: It is part of the anterior cavity and is present between the lens and iris.

Lens: It lies posterior to the cornea. It focuses visual image on the retina’s photoreceptors by altering its shape. It is suspended between the posterior cavity and the posterior chamber, which is part of the anterior cavity.

Iris: The boundary between the posterior and anterior chamber is formed by the iris. It consists of the pigment cells, blood vessels, and the two layers of smooth muscle cells that are parts of the intrinsic eye muscles.

Conclusion

Therefore, the anatomical features of the eye that are indicated in the structure given above are:

(a)	Posterior cavity
(b)	Posterior chamber
(c)	Lens
(d)	Iris
