This is two different questions: The Ciliary Body extends from the Choroid Coat and contains the Ciliary Muscles and the Ciliary Processes. However, it is the Suspensory Ligaments, which extend from the Ciliary Processes, that control the shape of the Lens.
The ciliary muscles and suspensory ligaments, along with the structure of the lens itself, enable the lens to adjust shape to facilitate focusing, a phenomenon called accommodation.
The ciliary muscle, part of the retina of the eye, changes the focal length of the lens by flattening it or making it more spherical.
There are no muscles which change the shape of the eye, although there are muscles which dilate and constrict the iris.

How does ciliary muscle change the shape of the lens?
its a muscle
What is the shape of the lens controlled by?
The shape of the lens is controlled by the ciliary muscle in the eye. The ciliary muscle adjusts the shape of the lens to allow for focusing on objects at different distances, a process known as accommodation.
What modification of the choroid that controls the shape crystalline lens?
ciliary bodyciliary body
What is effect of contraction and relaxation of the ciliary muscle?
change in shape of lens.
What structre changes the the shape of the lens for far and near vision?
The ciliary muscle is responsible for changing the shape of the lens to enable the eye to focus on objects at different distances. When focusing on far objects, the ciliary muscle relaxes, causing the lens to flatten. When focusing on near objects, the ciliary muscle contracts, causing the lens to round up.
What controlls the shape of the lens?
The ciliary muscle, part of the retina of the eye, changes the focal length of the lens by flattening it or making it more spherical.
What are the smooth muscle fibers called that support the lens?
The smooth muscle fibers that support the lens in the eye are called ciliary muscles. These muscles contract and relax to change the shape of the lens, allowing for accommodation and focusing on objects at different distances.
What structure surrounding the lens that connects the choroid and it alters the shape of the lens?
The ciliary body, which consists of ciliary muscles and ciliary processes, is the structure that surrounds the lens and connects to the choroid. The ciliary body controls the shape of the lens through the action of the ciliary muscles, which can adjust the thickness of the lens to allow for focusing on objects at different distances.
What muscle is responsible for eye accommodation of near and distal vision?
The ciliary muscle is responsible for eye accommodation of near and distant vision. It contracts to change the shape of the lens, allowing the eyes to focus on objects at different distances.
What division alone stimulates the lens of the eye?
The parasympathetic division of the autonomic nervous system stimulates the lens of the eye to change shape and accommodate for near vision. This division causes the ciliary muscle to contract, which alters the shape of the lens to focus on nearby objects.
Contains the ciliary muscle of the eye?
The ciliary muscle is located within the eye and is responsible for controlling the shape of the lens, which is crucial for focusing on objects at different distances. Contraction and relaxation of the ciliary muscle affect the thickness of the lens, allowing for accommodation of near and far vision.
What happens to the shape of cilia muscles when they relax?
When the ciliary muscle is relaxed, the choroid acts like a spring pulling on the lens via the zonule fibers causing the lens to become flat.
