Ciliary muscle of the eye
WebOct 26, 2024 · The eye lens is a flexible transparent membranous structure. We can modify the curvature of the eye lens through contraction and relaxation action of the ciliary muscles. The modified curvature changes the focal length of the lens. When the ciliary muscles are relaxed, the lens membrane becomes thin that increases its focal length. Webcontrolled by changes in the ciliary muscles of the eye which control the shape of the lens. When the ciliary muscles of the ciliary body are relaxed, there is tension in the suspensory ligaments. This puts force on the lens to make it more flat for distant vision. For near vision, the ciliary muscles contract, which decreases tension in the ...

Did you know?
WebThe parasympathetic nervous system stimulates muscarinic receptors expressed on ciliary muscle cells that cause smooth muscle contraction, thus relieving tension on the suspensory ligaments and allowing for near vision. It is common to hear the terms “near-sighted” and “far-sighted.” These terms reference what the eye is best at doing. WebDec 16, 2002 · He also has observed a decrease in movement of the ciliary muscle with age. However, Dr. Kaufman suggests that the real change may be a stiffening of the connective tissue that attaches the muscle to the wall of the eye. So, although the muscle contracts, it cannot move effectively enough to allow the lens to change shape. 4
