ALS (amoytrophic lateral sclerosis) is a disorder that directly affects nerve cells that control movement. These nerve cells send impulses from the brain to control movement. When these nerve cells can no longer send messages for movement, much of the tissue involved with movement begins to atrophy (decline).
Based on organ system functions, which two organ systems are directly impacted by this disorder?
A-Muscular and skeletal
B-Muscular and respiratory
C-Nervous and muscular
D-Nervous and integumentary
It says nerve cells directly.
It says nerve cells can no longer tell muscles to move and they will waste away, like the result of sitting around drinking beer.
So I would say C
Tysm
To determine which two organ systems are directly impacted by ALS, we need to understand the functions of the organ systems mentioned in the options.
A. Muscular and Skeletal: The muscular system is responsible for controlling movement and the skeletal system provides support and framework for the body.
B. Muscular and Respiratory: The respiratory system is responsible for breathing, which involves the muscles of the lungs and the diaphragm.
C. Nervous and Muscular: The nervous system controls movement through nerve impulses, while the muscular system carries out these movements.
D. Nervous and Integumentary: The integumentary system (skin, hair, and nails) is not directly involved in movement or nerve impulse transmission.
Now, let's analyze the options:
A. Muscular and Skeletal: While ALS does affect muscle tissue, it does not directly impact the skeletal system.
B. Muscular and Respiratory: ALS directly affects the nerve cells that control movement, which includes the muscles involved in breathing. Therefore, this option is a possibility.
C. Nervous and Muscular: ALS directly affects the nerve cells that control movement, which confirms that both the nervous system and muscular system are impacted by the disorder. This option is another possibility.
D. Nervous and Integumentary: As mentioned earlier, the integumentary system is not involved in movement or nerve impulse transmission, so this option is incorrect.
Based on the functions mentioned and the impact of ALS, the correct answer is:
C. Nervous and Muscular
