BFSP2 is a gene that encodes the protein phakinin ("beaded filament structural protein 2") in humans. [5]More than 99% of the vertebrate ocular lens consists of terminally differentiated lens fiber cells.
The lens is located towards the front part of the vertebrate eye, called the anterior segment, which includes the cornea and iris positioned in front of the lens. The lens is held in place by the suspensory ligaments (Zonule of Zinn), [1] attaching the lens at its equator to the rest of the eye [2] [3] through the ciliary body.
BFSP1 is a gene that encodes the protein filensin ("beaded filament structural protein 1") in humans. [5] [6]More than 99% of the vertebrate ocular lens is made up of terminally differentiated lens fiber cells.
The human eye is a sensory organ in the visual system that reacts to visible light allowing eyesight. Other functions include maintaining the circadian rhythm, and keeping balance. Arizona Eye Model. "A" is accommodation in diopters. The eye can be considered as a living optical device.
Sheep eye lens capsule with ligaments attached. The capsule is lifting off the lens showing cell fiber ends beneath. Microscope image of lens capsule in relation to lens cell types. The lens capsule is a component of the globe of the eye. [1] It is a clear elastic basement membrane similar in composition to other basement membranes in the body.
The simplest eyes are pit eyes. They are eye-spots which may be set into a pit to reduce the angle of light that enters and affects the eye-spot, to allow the organism to deduce the angle of incoming light. [1] Eyes enable several photo response functions that are independent of vision.
Alphagan P uses a purite preservative, which is better tolerated by those who have allergic reactions than the older BAK preservative in other eye drops. [13] Furthermore, less selective alpha agonists such as epinephrine may decrease the production of aqueous humor through vasoconstriction of the ciliary body (only for open-angle glaucoma).
The ciliary muscle is an intrinsic muscle of the eye formed as a ring of smooth muscle [3] [4] in the eye's middle layer, the uvea (vascular layer).It controls accommodation for viewing objects at varying distances and regulates the flow of aqueous humor into Schlemm's canal.
