Boundaries and Contents of the Quadrangular Space, Triangular Space, & Triangular Interval

The video tutorial explores the axillary region, focusing on the rotator cuff muscles and the posterior arm. It discusses three anatomical spaces: the cuadrangular space, triangular space, and triangular interval, highlighting their clinical significance due to the arteries and nerves passing through them. The tutorial provides a systematic method to learn the boundaries of these spaces using finger positioning. It also covers the differences when viewing from the right side and anterior view, noting the substitution of teres minor with subscapularis.
