The eye is an organ of the nervous system. To determine this, we can break down the question and analyze the options provided. The question asks which major body system the eye belongs to, and provides four options: integumentary, skeletal, nervous, and muscular.
To find the correct answer, we need to understand what each body system represents and then match it with the eye's function.
The integumentary system consists of the skin, hair, and nails, which protect the body from external factors. Although the eye is protected by the eyelids and eyelashes, it is not primarily a part of the integumentary system. Therefore, we can eliminate integumentary as a possible answer.
The skeletal system is responsible for providing support, protection, and movement of the body. While the eyeballs are situated within the eye sockets (orbits) of the skull, the eye itself is not composed of bones. Hence, the skeletal system is not the correct option.
The muscular system is responsible for movement and stability. It includes skeletal muscles, which allow voluntary movements, and smooth muscles, which are found in internal organs and control involuntary movements. While there are some muscles associated with the eye, such as the extraocular muscles that control eye movements, the eye itself is not primarily a muscular organ. Therefore, we can eliminate muscular as well.
Finally, we are left with the nervous system. The nervous system is responsible for receiving and transmitting information throughout the body. The eye, specifically the retina and optic nerve, plays a vital role in transmitting visual information to the brain for interpretation. Therefore, the eye is an organ of the nervous system, making "nervous" the correct answer.
In conclusion, the eye is an organ of the nervous system because it is responsible for transmitting visual information to the brain.
