Verified step by step guidance1
Step 1: Begin by identifying the latissimus dorsi muscle. The latissimus dorsi is a large, flat muscle that plays a key role in movements of the upper limb, such as extension, adduction, and internal rotation of the shoulder joint.
Step 2: Understand the anatomical location of the latissimus dorsi. It is situated in the lower back region and spans from the thoracic vertebrae, lumbar vertebrae, sacrum, and iliac crest to the humerus.
Step 3: Compare the descriptions provided in the question with the anatomical location of the latissimus dorsi. Eliminate options that do not match its location or size. For example, it is not located on the anterior chest wall, anterior thigh, or posterior lower leg.
Step 4: Focus on the correct description: 'It is a large muscle located on the lower back.' This matches the anatomical location and size of the latissimus dorsi.
Step 5: Conclude that the correct answer is the description that accurately reflects the latissimus dorsi's location and characteristics: 'It is a large muscle located on the lower back.'
