The effectors of the ______ nervous system are skeletal muscles.

• A. sympathetic
• B. somatic
• C. parasympathetic
• D. autonomic

Answer: (B)

Verified step by step guidance

1. Step 1: Begin by understanding the term 'effector' in the context of the nervous system. Effectors are the organs, tissues, or cells that respond to signals from the nervous system to carry out a specific function.
2. Step 2: Review the types of nervous systems mentioned in the problem: sympathetic, parasympathetic, autonomic, and somatic. Understand their roles and the types of effectors they control.
3. Step 3: Recall that the somatic nervous system specifically controls voluntary movements by sending signals to skeletal muscles, which are its effectors.
4. Step 4: Contrast this with the autonomic nervous system (which includes sympathetic and parasympathetic divisions). The autonomic nervous system controls involuntary functions and targets effectors such as smooth muscles, cardiac muscles, and glands.
5. Step 5: Based on the information above, identify that the correct answer is 'somatic,' as it is the nervous system responsible for controlling skeletal muscles.
