The ciliary muscle is relaxed when you look at something that is far away.

When the eye is looking at objects far in the distance the lens is and the ciliary muscle is?
TRUE
What does ciliary body do?
The ciliary body is behind the iris in the human eye. Tiny cilia (fibers) called zonules attach the ciliary body to the eye's lens. When focusing on close objects, the ciliary body contracts and the zonules relax, allowing the lens to thicken and improve the focus. When looking at a distant object, the ciliary body relaxes and the zonules contract, making the lens thinner for sharper distance vision.
What is the function of the ciliary body?
Consists of ciliary processes which capillaries secrete aqueous humor and ciliary muscle which changes the shape of lens for viewing objects in different distances.
What is the function of the ciliary escalator?
The ciliary body has three functions: accommodation, aqueous humor production and the production and maintenance of the lens zonules. Accommodation essentially means that when the ciliary muscle contracts, the lens becomes more convex, generally improving the focus for closer objects. When it relaxes, it flattens the lens, generally improving the focus for farther objects. One of the essential roles of the ciliary body is also the production of the aqueous humor, which is responsible for providing most of the nutrients for the lens and the cornea and involved in waste management of these areas.
What factors determine the force of gravity between two objects?
the mass of the objects and the distance of the objects
What part of the PNS controls the pupillary response?
Pupillary response is controlled by the autonomic nervous system.In bright light or when looking at close objects, the parasympathetic nervous system will cause pupillary constriction by activating the sphincter pupillae muscle(s). The parasympathetic nerves that innervate the sphincter pupillae are the short ciliary nerves, which come from the ciliary ganglion in the orbit. Innervation of the ciliary ganglion is via parasympathetic pre-ganglionic fibers traveling with the occulomoter nerve from the edinger-westfall nucleus in the cranial midbrain.In low light, when looking at distant objects, or when stress levels are high (fight or flight) the sympathetic nervous system will cause pupillary dilation by activating the iris dilator muscle(s). The sympathetic nerves that innervate these muscles come from the superior cervical ganglion.
Determined by the distance between objects and the difference in mass between the objects?
The distance between objects and the different is 0. The distance between the mass and an object is 1.
What two involuntary muscles make up the front part of the eye?
The two involuntary muscles that make up the front part of the eye are the iris and the ciliary body. The iris controls the size of the pupil, regulating the amount of light entering the eye. The ciliary body adjusts the shape of the lens, enabling the eye to focus on near or distant objects.
How is the gravitational force related to the distance between the objects?
its inversely proportional to the square of the distance between objects.
What is distance in math?
The distance between two objects.
How do you be safe with moving objects?
keep distance with moving objects.
What is the distance between two objects on a table?
take a measuring tape and measure the distance between the two objects
