Previous problemNext problem

Verified step by step guidance

Step 1: Understand the context of the question. The problem is asking for the approximate number of skeletal muscles in the human body, which is a fundamental concept in Anatomy & Physiology.

Step 2: Recall that skeletal muscles are the muscles attached to bones and are responsible for voluntary movements. They are distinct from smooth and cardiac muscles.

Step 3: Note that the human body contains approximately 650 skeletal muscles. This number is widely accepted in anatomical studies and textbooks.

Step 4: Eliminate the incorrect options provided in the question. For example, 'Roughly 1000' and 'Exactly 350' are not accurate representations of the number of skeletal muscles. Similarly, 'About 206' refers to the number of bones in the human body, not muscles.

Step 5: Conclude that the correct answer is 'Approximately 650,' based on anatomical evidence and standard references in the field of Anatomy & Physiology.
