Which option is a part of the Somatic System?

• A. Skeletal
• B. Endocrine
• C. Lymphatic
• D. Cardiac

Answer: (A)

The somatic system governs voluntary control of movement through motor neurons that activate skeletal muscles. Skeletal muscle is directly controlled by these somatic nerves, so it fits as part of the somatic system. The other options belong to different systems: endocrine handles hormones, the lymphatic system deals with immune drainage and fluid balance, and the cardiac area relates to the heart within the circulatory system (and is generally controlled automatically, not voluntarily). So skeletal is the correct part of the somatic system.
