Incapacitating the muscles of a mammalian eye would result in an inability __________.
A
to perceive color
B
to expel aqueous humor from the eye, resulting in glaucoma
C
of the photoreceptor cells to transduce light energy
D
to focus light and an inability of the photoreceptor cells to transduce light energy
E
to focus light onto the retina
Verified step by step guidance1
Understand the role of eye muscles: The muscles in the eye, particularly the ciliary muscles, are responsible for adjusting the lens to focus light onto the retina. This process is known as accommodation.
Identify the function of photoreceptor cells: Photoreceptor cells, such as rods and cones, are responsible for transducing light energy into neural signals. This process is separate from the focusing mechanism.
Analyze the options: Consider each option in the context of the role of eye muscles. The ability to perceive color and the transduction of light energy by photoreceptor cells are not directly dependent on the eye muscles.
Evaluate the correct option: The primary function of the eye muscles is to focus light onto the retina. If these muscles are incapacitated, the eye would struggle to focus light properly, leading to blurred vision.
Conclude with the correct answer: Based on the analysis, the correct answer is that incapacitating the muscles of a mammalian eye would result in an inability to focus light onto the retina.
