Aqueous humour The aqueous humour is a transparent, gelatinous fluid similar to plasma, but containing low protein concentrations. It is secreted from the ciliary epithelium, a structure supporting the lens. It is located in the anterior and posterior chambers of the eye, the space between the lens and the cornea.It is not to be confused with vitreous humour, which is contained within the larger cavity of the eye behind the lens.he drainage route for aqueous humour flow is first through the posterior chamber, then the narrow space between the posterior iris and the anterior lens (contributes to small resistance), through the pupil to enter the anterior chamber.

Functions of the Integumentary System Processing primarily occurs in the primary somatosensory area in the parietal lobe of the cerebral cortex: information is sent from the receptors via sensory nerves, through tracts in the spinal cord and finally into the brain.he somatosensory system is spread through all major parts of a mammal 's body (and other vertebrates). It consists both of sensory receptors and sensory (afferent) neurons in the periphery (skin, muscle and organs for example), to deeper neurons within the central nervous system.

Eye Anatomy: How Do Our Eyes Work? The Vitreous Humor and Aqueous Humor. Vitreous humor makes up approximately 80 percent of the volume of the eyeball. It is a gel-like substance in the back part of the eye that provides the shape of the eyeball. The vitreous humor is located between the lens and the retina, in an area called the vitreous cavity.

Eye Floaters/Retina This fluid is secreted from the ciliary body, then percolates around the lens, flushes the cornea and the iris, and finally exits through the angle of the eye that can become blocked in glaucoma. The vitreous humor is gelatinous in texture. This fluid fills all of the inside of the eye behind the lens. It develops before birth to support the retina and allow blood vessels to nourish the lens during fetal life.

Eye The large cavity in back of the lens (the center of the eyeball) is filled with a clear gel-like substance called vitreous humor. Light passing through the lens on its way to the retina passes through the vitreous humor. The vitreous humor is 99 percent water and contains no cells.queous humor: Clear liquid filling the small cavities between the cornea and the iris and between the iris and the lens. Astigmatism: Vision disorder caused by an uneven curvature in the cornea (sometimes the lens), resulting in indistinct or slightly out-of-focus images.

Chapter 46: The eye 46-4 and 46-7). They are the site of secretion of the aqueous humor. The iris is a circular, pigmented diaphragm that lies anteiro to the lens in a more or less coronal plane (fig. 46-4). It is anchored peripherally to the ciliary body, whereas its central border is free and bounds the aperture known as the pupil.

- Aqueous humour flows around the crystalline lens and through the pupil into the anterior chamber. Most aqueous exits the eye through the passageways of the trabecular meshwork. The trabecular meshwork is a sieve-like drain that encircles the outer edge of the iris within the anterior chamber angle, formed where the iris inserts into the ciliary body.

About the Eye and How It Works Aqueous Humor. Aqueous humor is a clear, watery fluid contained in a chamber behind the cornea that helps bring nutrients to the ocular tissue. It is made behind the lens and flows to the front of the eye, where it is drained by a tissue called the trabecular meshwork.Problems with the flow of this fluid can lead to problems with the pressure inside the eye.ou can get a close-up look at different parts of the eye in this eye diagram from the National Institutes of Health. Diagram of the eye, viewed from the side. To understand this diagram of the eye, try to picture it as being split in two, like an apple that's been cut in half.
