Show Answer
Correct Answer – D
Ans. is ‘D’ i.e., Rhomboid major
Triangle of auscultation has the following boundaries
- Superiorly and medially, by the inferior portion of the Trapezius.
- Inferiorly, by the Latissimus Dorsi.
- Laterally, by the medial border of the scapula.
- The superficial floor of the triangle is formed by the Serratus anterior and the lateral portion of the erector spinae muscles.
- Deep to these muscles are the osseous portions of the 6″ and 7th ribs and the internal and external intercostal muscles.
- Typically, the Triangle of Auscultation is covered by the Scapula.
- To better expose the triangle and listen to respiratory sounds with a stethoscope, patients are asked to fold their arms across their chest, medially rotating the scapulae, while bending forward at the trunk, somewhat resembling a fetal position.
