2. The structure most responsible for focusing light rays that enter the eye. D) Lens

3. Helps maintain the intraocular pressure; located in the anterior part of the eye. A) Aqueous humor

4. Area of greatest visual acuity. C) Fovea centralis

Explanation:

1. The sensory layer of the eye.

The retina covers the inside of the eyeball. It is considered as the sensory organ of the eye, where the perceived images are projected, are processed in the form of a nerve impulse that leaves the optic nerve.

2. The structure most responsible for focusing light rays that enter the eye.

The lens are the transparent structure inside the eye that focuses light rays in the central part of the retina.

3. Helps maintain the intraocular pressure; located in the anterior part of the eye.

The aqueous humor, is a transparent aqueous fluid secreted by the ciliary body, this liquid derived from the blood plasma, distributes oxygen and nutrients to the upper part of the eye and eliminates residual products. The dynamics of production and elimination of aqueous humor is very important to keep intraocular pressure (IOP) within normal limits.

4. Area of greatest visual acuity.

The fovea, or also known fovea centralis, is the center of the visual field, it is a narrow area of the retina that only contains cones. Its function is to help us have a vision as clear as possible with all kinds of details and precision.

Sympathetic stimulation of arterioles in skeletal muscle is mediated by epinephrine acting on its β-adrenergic receptors.  

Sympathetic stimulation   of vasoconstriction occurs as a result of activation of α-1 adrenergic receptors by norepinephrine released by post-ganglionic sympathetic neurons.
