- Pectoralis major
- Pectoralis minor
- Subscapularis
- Intercostal muscles
Show Solution
The Correct Option is C
Solution and Explanation
Step 1: Picture the four-sided pyramid of the axilla. Each wall has its own muscular contributors, and the question asks specifically about the wall facing backward.
Step 2: Going from superior to inferior, the back wall is made of subscapularis on top, then teres major and latissimus dorsi. The single option that fits is subscapularis.
Step 3: Rule out the distractors. The two pectoralis muscles guard the front of the axilla, while the intercostals line the inner (rib-side) wall. None of these sit on the posterior wall.
Step 4: The clean answer for the posterior wall is therefore subscapularis.
\[\boxed{\text{Subscapularis}}\]
