• Light is further converged by the crystalline lens located posterior to the iris. (medscape.com)
  • Anterior chamber (between cornea and iris), Posterior chamber (between iris, zonule fibers and lens) and the Vitreous chamber (between the lens and the retina). (utah.edu)
  • Two pairs are rectus muscles running straight to the bony orbit of the skull orthogonal to each other (the superior rectus, the inferior rectus, the lateral rectus and the medial rectus muscles). (utah.edu)
  • This is the first and most powerful lens of the optical system of the eye and allows, together with the crystalline lens the production of a sharp image at the retinal photoreceptor level. (utah.edu)
  • Here, we ablate estrogen receptor alpha (ERα) in the medial basal hypothalamus and find a robust bone phenotype only in female mice that results in exceptionally strong trabecular and cortical bones, whose density surpasses other reported mouse models. (regenerativemedicine.net)
  • Stereotaxic guided deletion of ERα in the arcuate nucleus increases bone mass in intact and ovariectomized females, confirming the central role of estrogen signaling in this sex-dependent bone phenotype. (regenerativemedicine.net)
  • The sagittal section of the eye also reveals the lens which is a transparent body located behind the iris. (utah.edu)
  • The lens is suspended by ligaments (called zonule fibers) attached to the anterior portion of the ciliary body. (utah.edu)
  • Light rays are focused through the transparent cornea and lens upon the retina. (utah.edu)
  • The contraction or relaxation of these ligaments as a consequence of ciliary muscle actions, changes the shape of the lens, a process called accommodation that allows us to form a sharp image on the retina. (utah.edu)
  • We do not know whether they, like the crystalline lens and aqueous humor of the eye, have the optical properties necessary for the functions we would assign to them. (emergentpublications.com)
  • Increased Association of Deamidated αA-N101D with Lens membrane of transgenic αAN101D vs. wild type αA mice: potential effects on intracellular ionic imbalance and membrane disorganization. (medscape.com)
  • a large oval nucleus and is devoid of pigment, while the inner portion is filled with pigment and extends as a series of thread-like processes amongst the outer segments of the rods and cones. (co.ma)
  • Plastic lens: The central part of the cornea gets oxygen from the outside air. (earthslab.com)
  • Thus, the soft plastic contact lenses worn for long intervals must be permeable to the air in order that oxygen can reach the cornea. (earthslab.com)
  • Prospective assessment of plate-haptic rotationally asymmetric multifocal toric intraocular lens with near addition of + 1.5 diopters. (medscape.com)
