What is the triangle of auscultation formed by?
The triangle of auscultation is an area of the posterior thoracic wall that is subcutaneous, providing for better auscultation. The triangle is bounded by the latissimus dorsi, trapezius, and medial border of the scapula. The 6th intercostal space lies in the floor.
What are the anatomical borders of the triangle of auscultation?
The Triangle of auscultation is an important landmark that resembles a small triangular interval. Its boundaries medially are the lateral border of the trapezius muscle, laterally by the medial border of the scapula, and inferiorly by the upper border of the lattisimus dorsi.
How can the triangle of auscultation be enlarged?
The triangle of auscultation is a small area of the back where three muscles (trapezius, latissimus dorsi, and rhomboideus major) converge. This area is near the scapula and becomes enlarged when a person leans forward with arms folded across the chest.
What is neck triangle?
The triangles of the neck are the topographic areas of the neck bounded by the neck muscles. The sternocleidomastoid muscle divides the neck into the two major neck triangles; the anterior triangle and the posterior triangle of the neck, each of them containing a few subdivisions.
What goes through the lumbar triangle?
The margins of the inferior lumbar (Petit’s) triangle are composed of the iliac crest inferiorly and the margins of two muscles – latissimus dorsi (posteriorly) and external abdominal oblique (anteriorly). The floor of the inferior lumbar triangle is the internal abdominal oblique muscle.
What are the four types of normal breath sounds?

What is Petit triangle?
Inferior lumbar (Petit) triangle The margins of the inferior lumbar (Petit’s) triangle are composed of the iliac crest inferiorly and the margins of two muscles – latissimus dorsi (posteriorly) and external abdominal oblique (anteriorly).
What is the clinical significance of the triangle of Petit?
Petit’s triangle is an anatomical landmark that is usually not clinically significant and only alluded to during multiple-choice examinations. This case describes the clinical ramification of this area of weakness and allows us to revisit and relearn the anatomy, and its relevance in clinical practice.
